[ I'm moving this thread across to www-rdf-interest as per my announcement of the RDF-DEV lists retirement[1]. Anyone following up, please send only to www-rdf-interest. (RDF Interest Group members: you may have missed this. We've recently had an influx of new listmembers from the older RDF-DEV list - I thought it sensible to consolidate around a single mailing list to avoid fragmentation).] Anyway, and straying off the original topic, this announcement reminds me that the simple RDF datasource API in SiRPAC was only intended as a stopgap, and that standardised parser APIs for RDF would be enormously useful... Since we have a new version of SiRPAC looming, and have recently had a second Perl parser for RDF announced (not to mention the libwww C-translation of the SiRPAC parser and the Mozilla.org implemention [2]), I suspect now would be good time to revisit the topic of RDF APIs. SiRPAC currently includes a very simple RDF parser API defining RDF Consumer and DataSource objects. A number of other approaches have been used elsewhere -- with SiRPAC being re-released, it seems sensible to invite suggestions about improvements that might be made to the way SiRPAC interfaces with other RDF-based applications. RDF-DEV folks will remember a thread back in June in which Ron Daniel began discussions of a community-driven API for RDF ("RADIX"). The mail archives for these remain online and searchable [3]. Since then there have been a number of new developments which make RADIX seem like a good thing to spend time on: more parsers in development, the Cambridge Communique clarifications about the relationship between RDF and XML [4], new applications such as GINF and DATAX, as well as the submission to OMG of a CORBA interface to RDF [5]). The Cambridge Communique on RDF and XML makes a point of saying: 8. A new simplified XML transfer syntax for RDF and an API for accessing RDF data models should be produced. This latter point (an RDF API) strikes me as a good reason to revisit the notion of a simple lightweight RDF API, and the RDF Interest Group is chartered to explore exactly these issues. So... it might be worth starting with Ron's original RADIX post, 'A proposal for an RDF API'[6] in the RDF-DEV archives, and seeing where we go with that... cheers, Dan [1] http://www.mailbase.ac.uk/lists/rdf-dev/1999-11/0000.html [2] all linked from http://www.w3.org/RDF/ [3] http://www.mailbase.ac.uk/lists/rdf-dev/search.html http://www.mailbase.ac.uk/cgi-bin/webglimpse?query=radix&doand=yes&listname=rdf-dev&form=compact [4] http://www.w3.org/TR/1999/NOTE-schema-arch-19991007 [5] http://lists.w3.org/Archives/Public/www-rdf-interest/1999Oct/0004.html [6] http://www.mailbase.ac.uk/lists/rdf-dev/1999-06/0002.html
