Bibliographic/Developer Page/Metadata Implementation Proposal
The ODF TC has in principle approved enhanced metadata support [pdf] for ODF 1.2. This is fantastically cool stuff, and gives ODF:
1. a simple, flexible, and extensible data model (RDF)
2. the ability to use it to describe not just the document, but pieces within the document (tables, images, etc.), including ...
3. a new generic field
Redland seems to have the characteristics that would be good for OOo: flexible licensing, builds as C++, can use expat or libxml as the xml parser, support for contexts (allows named graphs), and it's mature.
There are also mature libraries in Java as well, but I'm assuming that'd be less ideal given OOo's C++ base.
So upon loading an ODF 1.2 metadata-enhanced file, OOo would just load each RDF file into an in-memory model as a subgraph, work with the data as needed using the Redland APIs, and then write it back out on save. Because of the context support, Redland can track which file to write which statements to.
So, for example, I imagine citation support would use the new generic text:meta-field and deal with two subgraphs: one for the field per se (written to "citations.rdf"), and the other for the bibliographic source metadata ("bibliography.rdf").
Anyway, just some ideas ...
