Is there an HDF5 schema description language?

Hi Sean – you might want to contact Dan Tetlow and/or Gerd Heber, see Gerd’s reply to Dan’s post of Feb 10 2015 in which he asks a very similar question and discusses the possible use of the HDF5 XML DTD for defining a schema.

Subject: [Hdf-forum] Is there an HDF5 schema description language?

I am wondering whether there is any standard language (or attempt to develop one) for describing HDF5 schemas. That is, a language for specifying:

- the rooted directed graph containing all the named objects (Groups, Datasets, Named Datatypes)
- the metadata (attributes, Datatype, Dataspace) associated with each named object

I am imagining something similar to JSONSchema:
