Hi Jonas, I've updated our reference, though I would encourage you to try to continue to service the original URL too if possible (see [1]) if this is within your control, since others' bookmarks, hyperlinks etc will get broken. Anyhow, looks like your Perl stuff is coming along nicely. I'm wondering how it might eventually plug together with some of the other Perl stuff out there, especially opensource code like Eric P's RDF parser, storage, query system [2]. Your API [3] looks pretty close to most other RDF systems I've seen (Sergey's Java API, Mozilla, EricP's stuff, recent discussions with Dave Beckett about librdf etc etc). I'd be interested to see some discussion about whether these different but similar looking frameworks can work together; in particular within the same language (ie. the Perl stuff). It'd be good, for example, to see an instance of your RDF::Source::DBI::Model class populated by using the W3C::RDF::Parser tool... Have you tried anything along these lines? Anyone else? Related topic: cross-language APIs. The Mozilla stuff for example can be called from C++ or Javascript, since they've used XP-IDL to define the API. I'm wondering how feasible it would be to make an IDL version of say Sergey's proposed API and project that into Perl... Plausible?
