+<PRE>
+
+
+Section 2: HDF File Organization
+================================
+
+1. Name and describe the two primary objects that can be stored in an HDF5
+   file:
+
+Answer: 
+Group: A grouping structure containing zero or more HDF5 objects, together
+       with supporting metadata.
+
+Dataset: A multidimensional array of data elements, together with
+         supporting metadata.
+
+2. What is an attribute?
+
+Answer: An HDF attribute is a user-defined HDF5 structure that provides extra
+        information about an HDF5 object.
+
+3. Give the path name for an object called "harry" that is a member of a
+   group called "dick," which in turn is a member of the root group.
+
+Answer: /dick/harry
+
+Section 3: The HDF5 API
+=======================
+
+Describe the purpose of each of the following HDF5 APIs:
+
+H5A, H5D, H5E, F5F, H5G, H5T, H5Z
+
+H5A: Attribute access and manipulation routines.
+H5D: Dataset access and manipulation routines.
+H5E: Error handling routines.
+F5F: File access routines.
+H5G: Routines for creating and operating on groups.
+H5T: Routines for creating and manipulating the datatypes of dataset elements.
+H5Z: Data compression routines.
+
+
+Section 4: Creating an HDF File
+===============================
+
+1. What two HDF5 routines must be called in order to create an HDF5 file?
+
+Answer: H5Fcreate and H5Fclose.
+
+2. What include file must be included in any file that uses the HDF5 library.
+
+Answer: hdf5.h must be included because it contains definitions and
+        declarations used by the library.
+
+3. An HDF5 file is never completely empty because as soon as an HDF5 file
+   is created, it automatically contains a certain primary object.  What is
+   that object?
+
+Answer: The root group.
+
+
+Section 5: Creating a Dataset
+=============================
+
+1. Name and describe two major datatype categories.
+
+Answer: atomic datatype - An atomic datatype cannot be decomposed into
+                          smaller units at the API level.
+        compound datatype - A compound datatype is a collection of atomic/  
+                            compound datatypes, or small arrays of such types.
+
+2. List the HDF5 atomic datatypes. Give an example of a predefined datatype.
+
+Answer: There are six HDF5 atomic datatypes: integer, floating point,
+        date and time, character string, bit field, opaque.
+        H5T_IEEE_F32LE - 4-byte little-endian, IEEE floating point,
+        H5T_NATIVE_INT - native integer  
+
+3. What does the dataspace describe? What are the major characteristics of the
+   simple dataspace? 
+
+Answer: The dataspace describes the dimensionality of the dataset. It is 
+        characterized by its rank and dimension sizes.  
+       
+4. What information needs to be passed to the H5Dcreate function, i.e.
+   what information is needed to describe a dataset at creation time?
+
+Answer:  dataset location, name, dataspace, datatype, and creation properties.
+
+
+Section 6: Reading from/Writing to a Dataset
+============================================
+
+1. What are six pieces of information which need to be specified for
+   reading and writing a dataset?
+
+Answer: A dataset, a dataset's datatype and dataspace in memory, the 
+        dataspace in the file, the transfer properties and data buffer.
+
+2. Why are both the memory dataspace and file dataspace needed for 
+   read/write operations, but only the memory datatype is specified for the 
+   datatype?
+
+Answer: A dataset's file datatype is specified at creation time and cannot be 
+        changed. Both file and memory dataspaces are needed for performing
+        subsetting and partial I/O operations.  
+
+3. What does the line DATASPACE { SIMPLE (4 , 6 ) / ( 4 , 6 ) } in Fig 6.1 
+   means?
+
+Answer: It means that the dataset "dset" has a simple dataspace with the 
+        current dimensions (4,6) and the maximum size of the dimensions (4,6).
+
+
+Section 7: Creating an Attribute
+================================
+
+1. What is an attribute?
+
+Answer: An attribute is a dataset attached to an object. It describes the 
+        nature and/or the intended usage of the object.
+
+2. Can partial I/O operations be performed on attributes?
+
+Answer: No
+
+
+Section 8: Creating a Group
+===========================
+
+What are the two primary objects that can be included in
+a group?
+
+Answer:  A group and a dataset
+
+
+Section 9: Creating Groups using Absolute/Relative Names
+========================================================
+
+1. Group names can be specified in two "ways".  What are these
+   two types of group names that you can specify?
+
+Answer: relative and absolute
+
+2. You have a dataset named "moo" in the group "boo", which is 
+   in the group "foo", which in turn, is in the root group.  How would 
+   you specify an absolute name to access this dataset?
+
+Answer: /foo/boo/moo
+
+Section 10: Creating Datasets in Groups
+=======================================
+
+Describe a way to access the dataset "moo" described in the previous section
+(Section 9, question 2), using a relative and absolute pathname.
+
+Answers: 1. Access the group, "/foo", and get the group ID.
+            Access the group "boo" using the group ID obtained in Step 1.
+            Access the dataset "moo" using the group ID in Step 2.
+               gid = H5Gopen (file_id, "/foo", 0);       /* absolute path */
+               gid1 = H5Gopen (gid, "boo", 0);           /* relative path */
+               did = H5Dopen (gid1, "moo");              /* relative path */
+  
+         2. Access the group, "/foo", and get the group ID.
+            Access the dataset "boo/moo", with the group ID just obtained.
+               gid = H5Gopen (file_id, "/foo", 0);       /* absolute path */
+               did = H5Dopen (gid, "boo/moo");           /* relative path */
+             
+         3. Access the dataset with an absolute path.
+               did = H5Dopen (file_id, "/foo/boo/moo");  /* absolute path */

+The HDF5 library provides several interfaces, and is currently implemented in
+C.  The APIs provide routines for accessing HDF5 files and creating and
+manipulating HDF5 objects. All C routines in the HDF5 library begin with
+a prefix of the form H5*, where * is a single letter indicating the object on
+which the operation is to be performed. The APIs are listed below:

+<H2>Creating Compound Data Types</H2>
+A compound data type is similar to a struct in C or a common block in 
+Fortran. It is a collection of one or more atomic types or small arrays of 
+such types. To create and use a compound data type you need to refer to 
+various properties of the data compound data type: 
+<UL>
+  <LI>It is of class compound. 
+  <LI>It has a fixed total size, in bytes. 
+  <LI>It consists of zero or more members (defined in any order) with 
+      unique names and which occupy non-overlapping regions within the datum. 
+  <LI>Each member has its own data type. 
+  <LI>Each member is referenced by an index number between zero and N-1, 
+      where N is the number of members in the compound data type. 
+  <LI>Each member has a name which is unique among its siblings in a 
+      compound data type. 
+  <LI>Each member has a fixed byte offset, which is the first byte 
+      (smallest byte address) of that member in a compound data type. 
+  <LI>Each member can be a small array of up to four dimensions.
+</UL>
+Properties of members of a compound data type are defined when the 
+member is added to the compound type and cannot be subsequently modified. 
+<P>
+Compound data types must be built out of other data types. First, one 
+creates an empty compound data type and specifies its total size. Then 
+members are added to the compound data type in any order. 
+
+<H2> Programming Example</H2>
+<A NAME="desc">
+<H3><U>Description</U></H3>      
+
+This example shows how to create a compound data type, write an array 
+to the file which uses the compound data type, and read back subsets of 
+the members.<BR>

+<H2>What is an Attribute?</h2>
+<P>
+Attributes are small datasets that can be used to describe the nature and/or
+the intended usage of the object they are attached to. In this section, we
+show how to create and read/write an attribute.
+<P>
+<P>
+<H3>Creating an attribute</H3>
+<P>
+  Creating an attribute is similar to the creation of a dataset. To create an
+  attribute the application must specify the object which the attribute is
+  attached to, the data type and space of the attribute data and the creation
+  properties.
+<P>
+  The steps to create an attribute are as follows:
+<OL>
+    <LI> Obtain the object identifier that the attribute is to be attached to.
+    <LI> Define the characteristics of the attribute and specify creation
+       properties.
+    <UL>
+       <LI> Define the data type.
+       <LI> Define the dataspace.
+       <LI> Specify the creation properties.
+    </UL>
+    <LI> Create the attribute.
+    <LI> Close the attribute and data type, dataspace, and creation property
+       list if necessary.
+</OL>
+<P>
+ To create an attribute, the calling program must contain the following calls:
+<PRE>
+     attr_id = H5Acreate(loc_id, attr_name, type_id, space_id, create_plist);

+<H3>Reading/Writing an attribute</H3>
+<P>
+  Attributes may only be read/written as an entire object. No partial I/O is
+  currently supported. Therefore, to perform I/O operations on an attribute, the
+  application needs only to specify the attribute and the attribute's memory
+  data type.
+<P>
+  The steps to read/write an attribute are as follows.
+<OL>
+    <LI> Obtain the attribute identifier.
+    <LI> Specify the attribute's memory data type.
+    <LI> Perform the desired operation.
+    <LI> Close the memory data type if necessary.
+</OL>
+<P>
+To read/write an attribute, the calling program must contain the following
+  calls:
+<PRE>
+    status = H5Aread(attr_id, mem_type_id, buf);
+</PRE>
+    or
+<PRE>
+    status = H5Awrite(attr_id, mem_type_id, buf);

+<H2>What is a Dataset?</h2>
+<P>
+A dataset is a multidimensional array of data elements, together with
+supporting metadata. To create a dataset, the application program must specify
+the location to create the dataset, the dataset name, the data type and space
+of the data array, and the dataset creation properties.
+<P>
+  <H3> Data Types</H3>
+    A data type is a collection of data type properties, all of which can
+    be stored on disk, and which when taken as a whole, provide complete
+    information for data conversion to or from that data type.
+<P>
+    There are two categories of data types in HDF5: atomic and compound data
+    types. An atomic type is a type which cannot be decomposed into smaller
+    units at the API level. A compound data type is a collection of one or more
+    atomic types or small arrays of such types.
+<P>
+    Atomic types include integer, float, date and time, string, bit field, and
+    opaque. Figure 5.1 shows the HDF5 data types. Some of the HDF5 predefined
+    atomic data types are listed in Figure 5.2. In this tutorial, we consider 
+    only
+    HDF5 predefined integers. For information on data types, see the HDF5 
+    User's Guide.

+
+  <H3>Dataspaces</H3>
+
+    A dataspace describes the dimensionality of the data array. A dataspace
+    is either a regular N-dimensional array of data points, called a simple
+    dataspace, or a more general collection of data points organized in
+    another manner, called a complex dataspace. Figure 5.3 shows HDF5 dataspaces.
+    In this tutorial, we only consider simple dataspaces.
+<P>
+    <B>Fig 5.3</B> &nbsp;  <I>HDF5 dataspaces</I>
+<PRE>
+
+                         +-- simple
+       HDF5 dataspaces --|
+                         +-- complex
+
+</PRE>
+    The dimensions of a dataset can be fixed (unchanging), or they may be
+    unlimited, which means that they are extendible. A dataspace can also
+    describe portions of a dataset, making it possible to do partial I/O
+    operations on selections.
+
+ <h3>Dataset creation properties</H3>
+
+    When creating a dataset, HDF5 allows users to specify how raw data is
+    organized on disk and how the raw data is compressed. This information is 
+    stored in a dataset creation property list and passed to the dataset
+    interface. The raw data on disk can be stored contiguously (in the same 
+    linear way that it is organized in memory), partitioned into chunks and 
+    stored externally, etc. In this tutorial, we use the default creation 
+    property list; that is, no compression and
+    contiguous storage layout is used. For more information about the creation
+    properties, see the HDF5 User's Guide.
+
+<P>
+In HDF5, data types and spaces are independent objects, which are created
+separately from any dataset that they might be attached to. Because of this the
+creation of a dataset requires definitions of data type and dataspace.
+In this tutorial, we use HDF5 predefined data types (integer) and consider
+only simple dataspaces. Hence, only the creation of dataspace objects is
+needed.
+<P>
+
+To create an empty dataset (no data written) the following steps need to be
+taken:
+<OL>
+<LI> Obtain the location id where the dataset is to be created.
+<LI> Define the dataset characteristics and creation properties.
+ <UL>
+   <LI> define a data type
+   <LI> define a dataspace
+   <LI> specify dataset creation properties
+</UL>
+<LI> Create the dataset.
+<LI> Close the data type, dataspace, and the property list if necessary.
+<LI> Close the dataset.
+</OL>
+To create a simple dataspace, the calling program must contain the following
+calls:
+<PRE>
+   dataspace_id = H5Screate_simple(rank, dims, maxdims);
+   H5Sclose(dataspace_id );
+</PRE>
+
+To create a dataset, the calling program must contain the following calls:
+<PRE>
+   dataset_id = H5Dcreate(hid_t loc_id, const char *name, hid_t type_id,
+                          hid_t space_id, hid_t create_plist_id);

+<H2>What is an HDF5 file?</h2>
+<P>
+An HDF5 file is a binary file which contains scientific data and supporting
+metadata. The two primary objects stored in an HDF5 file are groups and 
+datasets. Groups and datasets will be discussed in the other sessions.
+<P>
+To create a file, the program application must specify a file name, file
+access mode, file creation property list, and file access property list.
+<P>
+<UL>
+  <LI><B> File Creation Property List:</B><BR>
+    The file creation property list is used to control the file metadata.
+    File metadata contains information about the size of the user-block, the
+    size of various file data structures used by the HDF5 library, etc.
+<P>
+    The user-block is a fixed length block of data located at the beginning
+    of the file which is ignored by the HDF5 library and may be used to store
+    any data information found to be useful to applications.
+<P>
+    For more details, see the HDF5 documentation. In this tutorial,
+    the default file metadata is used.
+<P>
+  <LI><B> File Access Property List:</B><BR>
+    The file access property list is used to control different methods of
+    performing I/O on files. See the HDF5 User's Guide for details. The default
+    file access property is used in this tutorial.
+</UL>
+<P>
+The steps to create and close an HDF5 file are as follows:
+<OL>
+  <LI> Specify the file creation and access property lists if necessary.
+  <LI> Create a file.
+  <LI> Close the file and close the property lists if necessary.
+</OL>
+To create an HDF5 file, the calling program must contain the following calls:
+
+<PRE>
+   file_id = H5Fcreate(filename, access_mode, create_id, access_id);
+

+HDF has developed tools to examine the contents of HDF5 files. The tool used
+in this tutorial is the HDF5 dumper, h5dump. h5dump is a tool that displays 
+the file contents in human readable form to an ASCII file in DDL.  DDL (Data 
+Description Language) is a language that describes HDF5 objects in Backus-Naur 
+Form. To view the file contents, type:

+Figure 4.1 describes the file contents of 'file.h5' using a directed graph.
+Each HDF5 object is represented by a rectangle and the arrows indicate 
+the structure of the contents. In Fig. 4.2, 'file.h5' contains
+a group object named '/' (the root group).

+<H2>Absolute vs. Relative Names</h2>
+<P>
+Recall that to create an HDF5 object, we have to specify the location where the
+object is to be created. This location is determined by the identifier of an HDF5
+object and the name of the object to be created. The name of the created
+object can be either an absolute name or a name relative to the specified 
+identifier.
+In Example 5, we used the file identifier and the absolute name "/MyGroup" to create a
+group. The file identifier and the name "/" specifies the location where the group
+"MyGroup" was created.
+<P>
+In this section, we discuss HDF5 names and show how to use absolute/relative
+names by giving an example of creating groups in a file.
+
+<H3>Names</H3>
+
+HDF5 object names are a slash-separated list of components. There are few
+restrictions on names: component names may be any length except zero and may
+contain any character except slash ("/") and the null terminator. A full name
+may be composed of any number of component names separated by slashes, with any
+of the component names being the special name ".". A name which begins with a
+slash is an absolute name which is accessed beginning with the root group of the
+file while all other relative names are accessed beginning with the specified
+group. Multiple consecutive slashes in a full name are treated as single slashes
+and trailing slashes are not significant. A special case is the name "/" (or
+equivalent) which refers to the root group.
+<P>
+Functions which operate on names generally take a location identifier which
+is either a file ID or a group ID and perform the lookup with respect to that
+location. Some possibilities are:
+

+<H2><U>Creating datasets in groups</U></H2>      
+We have shown how to create groups, datasets and attributes. In this section,
+we show how to create datasets in groups. Recall that H5Dcreate creates a
+dataset at the location specified by a location identifier and a name. Similar to
+H5Gcreate, the location identifier can be a file identifier or a group identifier and the name can be
+relative or absolute. The location identifier and the name together determine the
+location where the dataset is to be created. If the location identifier and name
+refers to a group, then the dataset is created in that group.
+
+
+<H2> Programming Example</H2>

+This example shows how to create a dataset in a particular group.
+It opens the file created in the previous example and creates two datasets.<BR>

+<H2>Creating an Extendible Dataset</H2>
+An extendible dataset is one whose dimensions can grow. In HDF5, it is possible to define a dataset to have certain initial dimensions, then later
+to increase the size of any of the initial dimensions. 
+<P>
+HDF5 requires you to use chunking in order to define extendible datasets. Chunking makes it possible to extend datasets efficiently, without
+having to reorganize storage excessively. 
+<P>
+The following operations are required in order to write an extendible dataset: 
+<OL>
+   <LI>Declare the dataspace of the dataset to have unlimited dimensions for all dimensions that might eventually be extended. 
+   <LI>Set dataset creation properties to enable chunking and create a dataset. 
+   <LI>Extend the size of the dataset.
+</OL>
+<H2> Programming Example</H2>
+<A NAME="desc">
+<H3><U>Description</U></H3>      
+This example shows how to create a 3 x 3 extendible dataset, write to that
+dataset, extend the dataset to 10x3, and write to the dataset again.

+An HDF5 file is a container for storing a variety of scientific data, and the 
+two primary HDF5 objects are groups and datasets.
+<UL>
+  <LI><B>HDF5 group:</B> a grouping structure containing zero or more HDF5 
+      objects, together with supporting metadata.
+
+  <LI><B>HDF5 dataset:</B> a multidimensional array of data elements, together 
+      with supporting metadata. 
+</UL>
+Any HDF5 group or dataset may have an associated attribute list. An HDF5
+attribute is a user-defined HDF5 structure that provides extra information
+about an HDF5 object.
+<P>
+Working with groups and group members (datasets for example) is similar in many
+ways to working with directories and files in UNIX. As with UNIX directories
+and files, objects in an HDF5 file are often described by giving their full (or
+absolute) path names.
+<UL>
+    <CODE>/</CODE> signifies the root group.<BR> 
+    <CODE>/foo</CODE> signifies a member of the root group called <I>foo</I>.
+<BR>
+    <CODE>/foo/zoo</CODE> signifies a member of the group <I>foo</I>, which in 
+    turn is a member of the root group. 
+</UL>
+<P>
+<!--
+In this tutorial, we consider:
+<UL>
+<LI>how to create a file 
+<LI>how to create a group
+<LI>how to create/read/write datasets
+<LI>how to create an attribute 
+<LI>how to create a grouping structure
+<LI>how to create datasets in groups 
+</UL>
+The rest of the tutorial is organized as follows:
+<UL>
+ <LI> Section 3 describes the HDF5 APIs.
+ <LI> Section 4 shows how to create an HDF5 file.
+ <LI> Section 5 shows how to create a dataset.
+ <LI> Section 6 shows how to read from and write to a dataset.
+ <LI> Section 7 shows how to create an attribute.
+ <LI> Section 8 shows how to create a group.
+ <LI> Section 9 discusses HDF5 names and shows how to create groups using absolute and relative names.
+ <LI> Section 10 shows how to create datasets in groups.
+</UL>
+
+Each section contains step by step instructions and an example. After the
+example, an HDF5 tool is used to examine the file contents. A formal definition
+of HDF5 objects in Backus-Naur Form is given last.
+
+The tutorial ends with a glossary and references.

+<DD>An HDF5 attribute is a small dataset that can be used to describe
+            the nature and/or the intended usage of the object it is attached 
+            to.
+
+<P>
+<DT><B>BOOT BLOCK</B>
+<DD>HDF5 files are composed of a "boot block" describing information required to portably access files on multiple platforms, followed by information
+about the groups in a file and the datasets in the file. The boot block contains information about the size of offsets and lengths of objects, the
+number of entries in symbol tables (used to store groups) and additional version information for the file. 
+<P>
+<DT><B>DATASET</B>     
+<DD>An HDF5 dataset is a multi-dimensional array of data elements, 
+            together with supporting metadata. 
+
+<P>
+<DT><B>DATASPACE</B>   
+<DD>An HDF5 dataspace is an object that describes the dimensionality
+            of the data array. A dataspace is either a regular N-dimensional
+            array of data points, called a simple dataspace, or a more 
+            general collection of data points organized in another 
+            manner, called a complex dataspace.
+
+<P>
+<DT><B>DATA TYPE</B>    
+<DD>An HDF5 Data Type is an object that describes the type of the 
+            element in an HDF5 multi-dimensional array. There are two 
+            categories of datatypes: atomic and compound data types. An 
+            atomic type is a type which cannot be decomposed into smaller 
+            units at the API level. A compound is a collection of one or 
+            more atomic types or small arrays of such types.
+
+<P>
+<DT><B>DATASET CREATION PROPERTY LIST</B>
+<DD>        The Dataset Creation Property List contains information on how 
+            raw data is organized on disk and how the raw data is compressed.
+            The dataset API partitions these terms by layout, compression,
+            and external storage:
+<UL>
+<B> Layout:</B>
+<UL>
+<LI> H5D_COMPACT: Data is small and can be stored in object header (not
+                  implemented yet).  This eliminates disk seek/read requests.
+<LI> H5D_CONTIGUOUS: (<B>default</B>) The data is large, non-extendible, 
+                     non-compressible, non-sparse, and can be stored 
+                     externally.
+<LI> H5D_CHUNKED:  The data is large and can be extended in any dimension.
+                   It is partitioned into chunks so each chunk is the same
+                   logical size. 
+</UL>
+<B>Compression:</B>  (gzip compression)<BR>
+<B>External Storage Properties:</B>  The data must be contiguous to be stored 
+                              externally. It allows you to store the data
+                              in one or more non-HDF5 files.
+
+</UL>
+
+<P>
+<DT><B>DATA TRANSFER PROPERTY LIST</B>
+<DD>        The data transfer property list is used to control various aspects 
+            of the I/O, such as caching hints or collective I/O information.
+<P>
+<DT><B>DDL</B>         
+<DD>DDL is a Data Description Language that describes HDF5 objects 
+            in Backus-Naur Form.
+ 
+<P>
+
+<DT><B>FILE ACCESS MODES</B>
+<DD>The file access modes determine whether an existing file will be 
+overwritten.  All newly created files are opened for both reading and
+writing.  Possible values are:
+<PRE>
+  H5F_ACC_RDWR:   Allow read and write access to file. 
+  H5F_ACC_RDONLY: Allow read-only access to file. 
+  H5F_ACC_TRUNC:  Truncate file, if it already exists, erasing all data 
+                  previously stored in the file. 
+  H5F_ACC_EXCL:   Fail if file already exists. 
+  H5F_ACC_DEBUG:  Print debug information. 
+  H5P_DEFAULT:    Apply default file access and creation properties. 
+</PRE>
+<P>
+<DT><B>FILE ACCESS PROPERTY LIST</B>
+   <DD>   File access property lists are used to control different methods 
+            of performing I/O on files:
+<UL>
+<B>Unbuffered I/O:</B> Local permanent files can be accessed with the functions 
+   described in Section 2 of the Posix manual, namely open(), lseek(), read(), 
+   write(), and close(). <BR>
+<B>Buffered I/O:</B> Local permanent files can be accessed with the functions 
+   declared in the stdio.h header file, namely fopen(), fseek(), fread(), 
+   fwrite(), and fclose().<BR>
+<B>Memory I/O:</B> Local temporary files can be created and accessed directly from 
+   memory without ever creating permanent storage. The library uses malloc() 
+   and free() to create storage space for the file<BR>
+<B>Parallel Files using MPI I/O:</B> This driver allows parallel access to a file 
+   through the MPI I/O library. The parameters which can be modified are the 
+   MPI communicator, the info object, and the access mode. The communicator 
+   and info object are saved and then passed to MPI_File_open() during file
+   creation or open. The access_mode controls the kind of parallel access the 
+   application intends.<BR> 
+<B>Data Alignment:</B> Sometimes file access is faster if certain things are aligned 
+   on file blocks. This can be controlled by setting alignment properties of 
+   a file access property list with the H5Pset_alignment() function. 
+</UL>
+<P>
+<DT><B>FILE CREATION PROPERTY LIST</B>
+<DD>     The file creation property list is used to control the file 
+            metadata. The parameters that can be modified are:
+<UL>
+ <B>User-Block Size:</B> The "user-block" is a fixed length block of data located 
+    at the beginning of the file which is ignored by the HDF5 library and may 
+    be used to store any data information found to be useful to applications. 
+<BR>
+<B> Offset and Length Sizes:</B> The number of bytes used to store the offset and 
+    length of objects in the HDF5 file can be controlled with this parameter. 
+ Symbol Table Parameters: The size of symbol table B-trees can be controlled 
+    by setting the 1/2 rank and 1/2 node size parameters of the B-tree. 
+<BR>
+<B> Indexed Storage Parameters:</B> The size of indexed storage B-trees can be 
+    controlled by setting the 1/2 rank and 1/2 node size parameters of the 
+    B-tree.
+</UL>
+<P>
+
+<DT><B>GROUP</B> 
+<DD>A Group is a structure containing zero or more HDF5 objects, 
+            together with supporting metadata. The two primary HDF5 objects 
+            are datasets and groups.
+<P>
+
+<DT><B>HDF5</B> 
+<DD>HDF5 is an abbreviation for Hierarchical Data Format Version 5. 
+            This file format is intended to make it easy to write and read 
+            scientific data
+<P>
+<UL>
+            <LI> by including the information needed to understand the data 
+              within the file
+<P>
+            <LI> by providing a library of C, FORTRAN, and other language 
+              programs that reduce the work required to provide efficient 
+              writing and reading - even with parallel IO
+</UL>
+<P>
+
+<DT><B>HDF5 FILE</B>
+<DD>An HDF5 file is a container for storing grouped collections 
+            of multi-dimensional arrays containing scientific data. 
+<P>
+
+<DT><B>H5DUMP</B> 
+<DD>h5dump is an HDF5 tool that describes the HDF5 file contents in DDL.
+<P>
+
+<DT><B>HYPERSLAB</B>
+<DD>
+A hyperslab is a portion of a dataset. A hyperslab selection can be a 
+logically contiguous collection of points in a dataspace, or it
+can be a regular pattern of points or blocks in a dataspace. 
+<P>
+<DT><B>NAMES</B> 
+<DD>HDF5 object names are a slash-separated list of components.  A name 
+            which begins with a slash is an absolute name which is accessed 
+            beginning with the root group of the file while all other relative 
+            names are accessed beginning with the specified group.
+<P>
+<DT><B>PARALLEL I/O (HDF5)</B>
+<DD>The parallel I/O version of HDF5 supports parallel file access using 
+MPI (Message Passing Interface).  
+<P> 
+
+<DT><B>THREADSAFE (HDF5)</B>
+<DD>A "thread-safe" version of HDF-5 (TSHDF5) is one that can be called from any thread of a multi-threaded program. Any calls to HDF
+can be made in any order, and each individual HDF call will perform correctly. A calling program does not have to explicitly lock the HDF
+library in order to do I/O. Applications programmers may assume that the TSHDF5 guarantees the following: 
+<UL>
+   <LI>   the HDF-5 library does not create or destroy threads. 
+   <LI>   the HDF-5 library uses modest amounts of per-thread private memory. 
+   <LI>   the HDF-5 library only locks/unlocks it's own locks (no locks are passed in or returned from HDF), and the internal locking is guaranteed to be deadlock free. 
+</UL>
+<P>
+These properties mean that the TSHDF5 library will not interfere with an application's use of threads. A TSHDF5 library is the same
+library as regular HDF-5 library, with additional code to synchronize access to the HDF-5 library's internal data structures.

+<BODY>
+Welcome to the HDF5 Tutorial provided by the HDF User Support Group.
+<P>
+HDF5 is a file format and library for storing scientific data. 
+HDF5 was designed and implemented to address the deficiencies of HDF4.x. 
+It has a more powerful and flexible data model, supports files larger than 2 GB,
+supports parallel I/O, and is thread-safe. For a short overview presentation 
+of the HDF5 data model, library and tools see:
+<PRE>
+   <A HREF="http://hdf.ncsa.uiuc.edu/HDF5/HDF5_overview/index.htm">http://hdf.ncsa.uiuc.edu/HDF5/HDF5_overview/index.htm</A>
+</PRE>
+This tutorial covers the basic HDF5 data objects and file structure, 
+the HDF5 programming model and the API functions necessary for creating and 
+modifying data objects. It also introduces the available HDF5 tools to access 
+HDF5 files.
+<P>
+The examples used in this tutorial, along with a Makefile to compile them
+can be found in <A HREF="./examples/">./examples/</A>. You can also download
+a <A HREF="http://hdf.ncsa.uiuc.edu/training/other-ex5/examples.tar">tar 
+file</A> with the examples and Makefile.  In 
+order to use the Makefile you may have to edit it and update the 
+compiler and compiler options, as well as the path for the HDF5
+binary distribution. 
+<P>
+Please check the <A HREF="references.html">References</A> for where to find 
+other examples of HDF5 Programs.
+<P> 
+We hope that the step-by-step examples and instructions will give you a quick
+start with HDF5.

+<H2>How to Iterate Over Group Members</H2>
+This section discusses how to find names and object types of HDF5 group 
+members.
+<P>
+The HDF5 Group interface has a function, H5Giterate, to iterate over the 
+group members.
+<P>
+Operations on each group member can be performed during the iteration process.
+The operator function and its data are passed to the iterator as parameters. 
+There are no restrictions on what kind of operations can be performed on 
+group members during the iteration procedure.
+<P>
+The following steps are involved:
+<OL>
+
+<LI> Write an operator function which will be used during the iteration process.
+     The HDF5 library defines the operator function signature and return values.
+<LI> Open the group to iterate through.
+<LI> Use H5Giterate to iterate through the group or just a few members of 
+     the group.
+</OL>
+<H2> Programming Example</H2>
+<A NAME="desc">
+<H3><U>Description</U></H3>      
+In this example we iterate through the members of the root group. The 
+operator function displays the members' names and their object types.
+The object type can be a group, dataset, or named datatype.

+      <LI> The second parameter is the name of the current object. The name is
+        passed to the operator function by the HDF5 library.
+      <LI> The third parameter is the operator data. It is passed to and from
+        the operator by the iterator, H5Giterate.
+
+       The operator function in this example just prints the name and type 
+       of the current object and then exits.
+
+       This information can also be used to open the object and perform 
+       different operations or queries. For example a named datatype object's
+       name can be used to open the datatype and query its properties. 
+</UL>
+<P>
+  The operator return value defines the behavior of the iterator.
+  <UL>
+      <LI>A zero return value causes the iterator to continue, returning
+        zero when all group members have been processed.
+      <LI>A positive value causes the iterator to immediately return that
+        value, indicating a short-circuit success. The iterator can be restarted
+        at the next group member.
+      <LI>A negative value causes the iterator to immediately return that value,
+       indicating failure. The iterator can be restarted at the next group 
+       member. 
+  </UL>
+<P>
+   In this example the operator function returns 0, which causes the iterator
+   to continue and go through all group members.
+<P>
+<LI>The function H5Gget_objinfo is used to determine the type of the object. 
+   It also returns the modification time, number of hard links, and some
+   other information.
+<P>
+   The signature of this function is as follows:
+<PRE>
+     herr_t H5Gget_objinfo(hid_t loc_id, const char * name, hbool_t follow_link,
+                            H5G_stat_t *statbuf)
+</PRE>
+<UL>
+       <LI> The first two arguments specify the object by its location and name.
+         This example uses the group identifier and name relative to the group
+         to specify the object. 
+       <LI> The third argument is a flag  which indicates whether a 
+            symbolic link should be followed or not. A zero value indicates 
+            that information should be returned for the link itself, but not 
+            about the object it points to.
+            The root group in this example does not have objects that are
+            links, so this flag is not important for our example.
+       <LI> The fourth argument is a buffer to return information in.
+         Type information is returned into the field "type" of the 
+         H5G_stat_t data structure (statbuf.type). Possible values are:
+         H5G_GROUP, H5G_DATASET, H5G_TYPE, and H5G_LINK.
+</UL>
+<P>
+<LI> The H5Giterate function has the following signature:
+<PRE>
+   int H5Giterate(hid_t loc_id, const char *name , idx,
+                  H5G_operator_t operator, void * operator_data) 
+</PRE>
+<UL>
+   <LI> The first parameter is the group for the group being iterated over.
+   <LI> The second parameter is the group name.
+   <LI> The third parameter specifies that iteration begins with the 
+        <I>idx</I> object in the group and the next element to be processed 
+        is returned in the <I>idx</I> parameter. In our example NULL is 
+        used to start at the first group member. Since no stopping point 
+        is returned in this case, the iterator cannot be restarted if one 
+        of the calls to its operator returns a non-zero value.
+   <LI> The fourth parameter is an operator function.
+   <LI> The fifth argument is the operator data. We used NULL since no 
+        data was passed to and from the operator. 
+</UL>

+<H2>Mounting Files</H2>
+
+HDF5 allows you to combine two or more HDF5 files in a manner similar to mounting
+files in UNIX. The group structure and metadata from one file appear as though
+they exist in another file. The following steps are involved:
+<OL>
+<LI>Open the files.
+
+<LI>Choose the "mount point" in the first file (parent). The "mount point" in 
+    HDF5 is a group ( it can also be the root group ).
+
+<LI>Use the HDF5 API function H5Fmount to mount the second file (child) in 
+    the first one.
+
+<LI>Work with the objects in the second file as if they were members of 
+   the "mount point" group in the first file.  The previous contents of
+   the "mount point" group are temporarily hidden.
+
+<LI>Unmount the second file using the H5Funmount function when the work is done.
+</OL>
+
+<H2> Programming Example</H2>
+<A NAME="desc">
+<H3><U>Description</U></H3>      
+
+In the following example we create one file with a group in it, and another
+file with a dataset. Mounting is used to access the dataset from the second 
+file as a member of a group in the first file. The following picture 
+illustrates this concept.
+<PRE>
+
+    'FILE1'                                 'FILE2'

+     the dataset is to be modified. 
+<P>

+        file specified by its handle <I>fid1</I>. Since group G is in the root 
+        group of the first file, one can also use just "G" to identify it. 
+<P>
+        Below is a description of another scenario:<BR>
+        Suppose group G was a member of group D in the first file (<I>fid1</I>).
+        Then mounting point G can be specified in two different ways:
+<P>
+<UL>
+          <LI> <I>loc_id</I> is <I>fid1</I><BR>
+               <I>name</I> is "D/G"      
+<P>
+          <LI> <I>loc_id</I> is an identifier of the group "D"<BR> 
+               <I>name</I> is just "G"  
+</UL>
+   <P>  
+    <LI> The third argument is an identifier of the file which will be mounted.
+         Only one file can be mounted per "mount point".
+<P>
+    <LI> The fourth argument is an identifier of the property list to be used.
+         Currently, only the default property list, H5P_DEFAULT, can be used.
+</UL>
+<P>
+<LI>  In this example we just read data from the dataset D. One can modify
+    data also. If the dataset is modified while the file is mounted, it becomes
+    modified in the original file too after the file is unmounted.
+<P>
+<LI> The file is unmounted with the H5Funmount function:
+<PRE>
+  herr_t H5Funmount(hid_t loc_id, const char *name)
+</PRE>
+    Arguments to this function specify the location of the "mount point".
+    In our example <I>loc_id</I> is an identifier of the first file, and 
+    <I>name</I> is the name of group G, "/G". One could also use "G" 
+    instead of "/G" since G is a member of the root group in the file 
+    <I>fid1</I>.  Notice that H5Funmount does not close files.  They are closed
+    with the respective calls to the H5Fclose function. Closing the parent
+    automatically unmounts the child.
+<P> 
+<LI>The h5dump utility cannot display files in memory, therefore no output 
+    of FILE1 after FILE2 was mounted is provided.

+
+
+Section 2: HDF File Organization
+================================
+
+1. Name and describe the two primary objects that can be stored in an HDF5
+   file:
+
+2. What is an attribute?
+
+3. Give the path name for an object called "harry" that is a member of a
+   group called "dick," which in turn is a member of the root group.
+
+
+Section 3: The HDF5 API
+=======================
+
+Describe the purpose of each of the following HDF5 APIs:
+
+H5A, H5D, H5E, F5F, H5G, H5T, H5Z
+
+
+
+Section 4: Creating an HDF File
+===============================
+
+1. What two HDF5 routines must be called in order to create an HDF5 file?
+
+2. What include file must be included in any file that uses the HDF5 library.
+
+3. An HDF5 file is never completely empty because as soon as an HDF5 file
+   is created, it automatically contains a certain primary object.  What is
+   that object?
+
+
+
+Section 5: Creating a Dataset
+=============================
+
+1. Name and describe two major datatype categories.
+
+2. List the HDF5 atomic datatypes. Give an example of a predefined datatype.
+
+3. What does the dataspace describe? What are the major characteristics of the
+   simple dataspace? 
+
+4. What information needs to be passed to the H5Dcreate function, i.e.
+   what information is needed to describe a dataset at creation time?
+
+
+Section 6: Reading from/Writing to a Dataset
+============================================
+
+1. What are six pieces of information which need to be specified for
+   reading and writing a dataset?
+
+2. Why are both the memory dataspace and file dataspace needed for 
+   read/write operations, but only the memory datatype is specified for the 
+   datatype?
+
+3. What does the line DATASPACE { SIMPLE (4 , 6 ) / ( 4 , 6 ) } in Fig 6.1 
+   means?
+
+
+Section 7: Creating an Attribute
+================================
+
+1. What is an attribute?
+
+2. Can partial I/O operations be performed on attributes?
+
+
+Section 8: Creating a Group
+===========================
+
+What are the two primary objects that can be included in
+a group?
+
+
+Section 9: Creating Groups using Absolute/Relative Names
+========================================================
+
+1. Group names can be specified in two "ways".  What are these
+   two types of group names that you can specify?
+
+2. You have a dataset named "moo" in the group "boo", which is 
+   in the group "foo", which in turn, is in the root group.  How would 
+   you specify an absolute name to access this dataset?
+
+
+Section 10: Creating Datasets in Groups
+=======================================
+
+Describe a way to access the dataset "moo" described in the previous section
+(Section 9, question 2), using a relative and absolute pathname.

+<H2>Reading to/Writing from a Dataset</h2>
+<P>
+During a dataset I/O operation, the library transfers raw data between memory
+and the file. The memory can have a data type different than the file data type
+and can also be a different size (memory is a subset of the dataset elements,
+or vice versa). Therefore, to perform read or write operations, the application
+program must specify:
+<UL>
+  <LI> The dataset
+
+  <LI> The dataset's data type in memory
+
+  <LI> The dataset's dataspace in memory
+
+  <LI> The dataset's dataspace in the file
+
+  <LI> The transfer properties (The data transfer properties control various
+    aspects of the I/O operations like the number of processes participating
+    in a collective I/O request or hints to the library to control caching of
+    raw data. In this tutorial, we use the default transfer properties.)
+
+  <LI> The data buffer
+</UL>
+
+
+<P>
+The steps to read to/write from a dataset are
+as follows:
+<OL>
+  <LI> Obtain the dataset identifier.
+  <LI> Specify the memory data type.
+  <LI> Specify the memory dataspace.
+  <LI> Specify the file dataspace.
+  <LI> Specify the transfer properties.
+  <LI> Perform the desired operation on the dataset.
+  <LI> Close the dataset.
+  <LI> Close the dataspace/data type, and property list if necessary.
+</OL>
+
+To read to/write from a dataset, the calling program must contain the following call:
+<PRE>
+   H5Dread(dataset_id, mem_type_id, mem_space_id, file_space_id,
+           xfer_plist_id, buf );
+</PRE>
+   or
+<PRE>
+   H5Dwrite(dataset_id, mem_type_id, mem_space_id, file_space_id,
+            xfer_plist_id, buf);
+</PRE>

+<H2> Programming Example</H2>

+<H3><U>Description</U></H3>      
+The following example shows how to read and write an existing dataset.
+It opens the file created in the previous example, obtains the dataset 
+identifier,  
+<I>/dset</I>, writes the dataset to the file, then reads the dataset back from 
+memory. It then closes the dataset and file. <BR>

+<H2>References to Objects</H2>
+In HDF5, objects (i.e. groups, datasets, and named data types) are usually 
+accessed by name. This access method was discussed in previous sections. 
+There is another way to access stored objects - by reference.
+<P>
+An object reference is based on the relative file address of the object header
+in the file and is constant for the life of the object. Once a reference to
+an object is created and stored in a dataset in the file, it can be used
+to dereference the object it points to. References are handy for creating
+a file index or for grouping related objects by storing references to them in
+one dataset.
+<P>
+<A NAME="def1">
+<H2>Creating and Storing References to Objects</H2>
+The following steps are involved in creating and storing file references
+to objects:
+<OL>
+<LI> Create the objects or open them if they already exist in the file.
+<P>
+<LI> Create a dataset to store the objects' references.
+<P>
+<LI> Create and store references to the objects in a buffer.
+<P>
+<LI> Write a buffer with the references to the dataset.
+</OL>
+
+
+<H2> Programming Example</H2>
+<A NAME="desc1">
+<H3><U>Description</U></H3>      
+The example below creates a group and two datasets and a named data type in the
+group. References to these four objects are stored in the dataset in the root
+group.  [<A HREF="examples/h5_ref2objw.c">Download h5_ref2objw.c</A>]

+<H2>References to Dataset Regions</H2>
+Previously you learned about creating, reading, and writing
+dataset selections. Here you will learn how to store dataset
+selections in a file, and how to read them back using references
+to the dataset regions.
+<P>
+A dataset region reference points to the dataset selection by storing the
+relative file address  of the dataset header and the global heap offset of
+the referenced selection.  The selection referenced is located by retrieving
+the coordinates of the areas in the selection from the global heap. This
+internal mechanism of storing and retrieving dataset selections is transparent
+to the user. A reference to the dataset selection ( region ) is constant for 
+the life of the dataset.
+<A NAME="def1">
+<H2>Creating and Storing References to Dataset Regions</H2>
+The following steps are involved in creating and storing references to
+the dataset regions:
+<OL>
+
+<LI> Create a dataset to store the dataset regions (selections).
+<P>
+<LI> Create selections in the dataset(s). Dataset(s) should already exist in the
+   file.
+<P>
+<LI> Create references to the selections and store them in a buffer.
+<P>
+<LI> Write references to the dataset regions in the file.
+<P>
+<LI> Close all objects.
+</OL>
+
+<H2> Programming Example</H2>
+<A NAME="desc1">
+<H3><U>Description</U></H3>      
+The example below creates a dataset in the file. Then it creates a 
+dataset to store references to the dataset regions (selections).
+The first selection is a 6 x 6 hyperslab. The second selection is a point 
+selection in the same dataset.
+References to both selections are created and stored in the buffer, and then
+written to the dataset in the file.

+Notice how raw data of the dataset with the dataset regions is displayed.
+Each element of the raw data consists of a reference to the dataset 
+(DATASET  number1:number2) and its selected region. 
+If the selection is a hyperslab, the corner coordinates of the hyperslab 
+are displayed. 
+For the point selection, the coordinates of each point are displayed.
+Since only two selections were stored, the third and fourth elements of the 
+dataset "Dataset1" are set to NULL. This was done by the buffer 
+inizialization in the program.

+The following example reads a dataset containing dataset region references.
+It reads data from the dereferenced dataset and displays the number of 
+elements and raw data. Then it reads two selections:
+hyperslab and point. The program queries a number of points in the 
+hyperslab  and the coordinates and displays them. Then it queries a number of 
+selected points and their coordinates and displays the  information.<BR>

+Hyperslabs are portions of datasets. A hyperslab selection can be a logically contiguous collection of points in a dataspace, or it
+can be a regular pattern of points or blocks in a dataspace.
+You can select a hyperslab to write to/read from with the function

+<H2>Selecting Independent Points and Copying a Dataspace</h2>
+You can select independent points to read or write to in a 
+dataspace by use of the H5Sselect_elements function. 
+<P>
+The H5Scopy function allows you to make an exact copy of a dataspace,
+which can help cut down on the number of function calls needed when
+selecting a dataspace.
+<P>
+<H2> Programming Example</H2>
+<A NAME="desc">
+<H3><U>Description</U></H3>      
+This example shows you how to use H5Sselect_elements to select individual
+points in a dataset and how to use H5Scopy to make a copy of a dataspace.
