Intiailal overview of Catalog 2.0 specification.
Metadata entity, and metadata element are still used extensively in the Catalog specificaiton. So readers of that specification will not find our classes entirely unexpected.
A full BNF is given for a query lanaguage (abilities are very similar to the Simple Feature for SQL).
CORBRA bindings are given, offering great insite into the expected mapping of Catalog Constructs into code. Unfortantly metadata is refered to as a "any"
HTTP / SOAP bindings are given - this may be the replacement of the WRS Dragt document from 1999?
- Ape the CORBRA bindings as a starting point
- Do the usual java substitutions for take advantage of Collections, URL and so on
- Use MetadataEntity rather than "any"
