QAK
Summary
These are revisions to the last version of the HDF5 file DTD I modified from
Bob's original.
The changes are:
-
Added "UserBlock".
-
Revised SuperBlock information to have format version and length & offset
information.
-
Removed "Link" elements, per our discussion of them.
-
Changed a few OBJ-XID's from IMPLIED to REQUIRED.
-
Revised ChunkSize tag to have ndims and chunk sizes.
-
Removed ArrayType.
-
Removed Compression information from Dataset element, since it's in the
StorageLayout element.
-
Returned CompoundType to the v1.2 specification. (Allows fields to have
"arrayness" within compound datatype)
-
Changed Datasets, StoredDatatypes and Groups to have either the information
about the object or a pointer to the object with the information.
The revised DTD is here:
HDF5-DTD-2-QAK.dtd
Important Questions For Discussion
I did not attempt to tackle the problem of encoding the data itself.
