Conceptual reference by capability — properties, linear algebra, STL, filters, MPI, errors, architecture. Use this when you know what you want to do but not which API to call.

The seven sub-pages below cut h5cpp along a capability / concern axis, complementing the I/O tree (which is organised by object kind — file, dataset, attribute, group).

For deeper design rationale, taxonomies, inventories, and the usability evaluation, see the top-level REPORTS tab (architecture, inventories, taxonomies, surveys, compatibility, project — full reports tree).

Many of the pages above wrap pre-existing curated material from earlier sweeps (link_property_lists, link_linalg_template_types, link_error_handler, the Reports tree, etc.) — this index just gathers them under one nav axis.
