Appease clang-format. * Addressed Chris' comments. * Added an alias for asynchronous functions. * One space is enough for all of us. * Slightly restructured RM page. * address some issues * reformatting * Style external links. * reformatting * reformatting * Added "Metadata Caching in HDF5" as a technical note example. * Revise this soon! * Added specification examples. * Fixed references. * Added H5AC cache image stuff and file format study. * Added older FMT versions. Where did 1.0 go? * Updated C/C++ note and replaced ambiguous labels. * Reformat source with clang v10.0.1. * Added the VFL technical note. * Added what I believe might be called version 1.0 of the format. * Added the remaining specs. * Added H5Z callback documentation and fixed a few mistakes. * Added dox for deprecated H5G calls and fixed a few snippet blockIDs. * clang-format happy? * Ok? * Bonus track: Deprecated H5D functions. * Carry over the more detailed group description. * Added documentation for the missing and deprecated H5R calls. * Life is easier and less repetitive w/ snippets. Use them! * Eliminate the snippet block ID artifacts in the HTML rendering. * Fixed snippet HTML artifacts and added a few missing calls. * Under 20 H5Ps to go! * Almost complete! * "This is a form of pedantry up with which I will not put." (Churchill) * Let's not waste as much space on bulleted lists! * First complete (?) draft of the Doxygen-based RM. * Completeness check and minor fixes along the way. * Pedantry. * Adding missing H5FD calls checkpoint. * Pedantry. * More pedantry. * Added H5Pset_fapl_log. * First draft of H5ES. * Fixed warnings. * Prep. for map module. * First cut of the map module. * Pedantry. * Possible H5F introduction. * Fix the indentation. * Pedantry. * Ditto. * Thanks to the reviewers for their comments. * Added missing images. * Line numbers are a distraction here. * More examples, references, and clean-up. Don't repeat yourself! * Clang pedantry. * Ditto. * More reviewer comments... * Templatized references and cleaned up \todos. * Committing clang-format changes * Fixed MANIFEST. * Addressed Quincey's comments. (OCPLs) * Fixed a few more \todo items. * Fixed more \todo items. * Added attribute life cycle. * Forgot the examples file. * Committing clang-format changes * Pedantry. * Live and learn! * Added a sample H5D life cycle. * Committing clang-format changes * Pedantry.

+/**
+ * \defgroup H5M H5M
+ * \brief Map Interface
+ *
+ * \details \Bold{The interface can only be used with the HDF5 VOL connectors that
+ * implement map objects.} The native HDF5 library does not support this
+ * feature.
+ *
+ * While the HDF5 data model is a flexible way to store data, some
+ * applications require a more general way to index information. HDF5
+ * effectively uses key-value stores internally for a variety of
+ * purposes, but it does not expose a generic key-value store to the
+ * API. The Map APIs provide this capability to the HDF5 applications
+ * in the form of HDF5 map objects. These Map objects contain
+ * application-defined key-value stores, to which key-value pairs can
+ * be added, and from which values can be retrieved by key.
+ *
+ * HDF5 VOL connectors with support for map objects:
+ * - DAOS
+ *
+ * \par Example:
+ * \code
+ * hid_t file_id, fapl_id, map_id, vls_type_id;
+ * const char *names[2] = ["Alice", "Bob"];
+ * uint64_t IDs[2] = [25385486, 34873275];
+ * uint64_t val_out;
+ *
+ * <HDF5 VOL setup code ....>
+ *
+ * vls_type_id = H5Tcopy(H5T_C_S1);
+ * H5Tset_size(vls_type_id, H5T_VARIABLE);
+ * file_id = H5Fcreate("file.h5", H5F_ACC_TRUNC, H5P_DEFAULT, fapl_id);
+ * map_id = H5Mcreate(file_id, "map", vls_type_id, H5T_NATIVE_UINT64, H5P_DEFAULT, H5P_DEFAULT, H5P_DEFAULT);
+ * H5Mput(map_id, vls_type_id, &names[0], H5T_NATIVE_UINT64, &IDs[0], H5P_DEFAULT);
+ * H5Mput(map_id, vls_type_id, &names[1], H5T_NATIVE_UINT64, &IDs[1], H5P_DEFAULT);
+ * H5Mget(map_id, vls_type_id, &names[0], H5T_NATIVE_UINT64, &val_out, H5P_DEFAULT);
+ * if(val_out != IDs[0])
+ * ERROR;
+ * H5Mclose(map_id);
+ * H5Tclose(vls_type_id);
+ * H5Fclose(file_id);
+ * \endcode
