The Virtual Dataset design document below describes feature requirements, how the feature works, and why design choices were made.

RFC: HDF5 Virtual Dataset (PDF)  This document describes requirements that guided development of the Virtual Dataset (VDS) feature, feature constraints, several use cases, the VDS programming model, and some details of the implementation.

This document contains useful illustrations that provide an intuitive understanding of virtual datasets.

Note: The current version reflects the design, strategies, and general approach employed in the VDS feature, but the API implementation had to be modified from the specification. An expected update will correct this divergence.
