I exceeded 90% overall test coverage, so 0.01 is out on CPAN. I still have a lot of documentation to write.
Protocols: Embedded (basic Perl API - implies the REST interface), HTTP (POE HTTP server)
Formatters: Atom, RDF, JSON
For version 0.02, I'm aiming for overall coverage of 95%. I'm adding an RDF semantic that works with the model as a complete document instead of the Atom semantic of working with parts of the model as documents. More bug fixes. Better documentation.
Atom support is a bit sketchy at the moment. Resources can be managed, but categories, collections, workspaces, and services are still a work in progress.
JSON support is read-only for now. I hope to allow resources to be created/modified using JSON in 0.03. I'll also try to add YAML support in 0.03.
