Current RDF/Object Browser questions to research:

• Is Aaron Swartz's "perfect Python RDF API" mentioned in his original Semplesh email the current Semplesh API? Is it available/usable by outsiders?

  • See infogami which includes a web framework and a BerkeleyDB-based store.

• Is Edd Dumbill still using RDF for his PIM? What's his toolset/store? Is he storing any actual EMail/documents in it, or just Meta Data? How about a Note field for Contacts?

• How exactly is RDF used in Mozilla? Can I access it from outside Mozilla, if I want to build some other things that integrate with that data? Is the store still Mork, or something new?

• Do I still want to focus on Zope as my development environment? Are there any "widely" used RDF products for it?

• Is there any convergence yet on RDF query languages? I suspect not.

• Sean Palmer mentioned going from triples to quants/quints to support context associated with integrating multiple soups (personal data, group data, public data). Is there any coherent thinking here? Is this supported by any tools/stores yet? (keywords: Semantic Memory, SEM, Semantic Cloud - see Seth Russell posting )

  • Sean is working on an API called Eep3, which will become part of Semplesh.

  • [proposed](http://robustai.net/sem/doc/Data Structure.html) (Apr'01) Data Structure

• Has anyone done anything like storing a document/outline as a set of RDF nodes? Are there any big bumps there (e.g. controlling the sequence of sister nodes)? Is there something that makes this simply a stupid idea? The reason I'm considering it is to support maybe (a) Transclusion and (b) CoOutlining.
