Hi all, I also cced Andy Seaborne, Eric Prud'hommeaux, Richard Cyganiak and Christian Lehmann. To them, this mail is in reply to: http://dig.csail.mit.edu/breadcrumbs/node/140 and http://lists.w3.org/Archives/Public/www-archive/2006Jun/0003.html We are of course very interested in joining efforts on database to RDF mapping. So a sceduled chat or a BOF at ESWC are both good ideas. We plan to do the following stuff for D2RQ and D2R server in the next months: - implement a smarter SPARQL-to-SQL rewriting algorithm, which will speed up queries. Richard's "A relational algebra for SPARQL" was the first step into this direction. - do some fine tuning on the language and introduce some language constructs that make it easier to write mappings or make the language more flexible. Did anybody hear of use cases where something couldn't be mapped using D2RQ? - improve Richard's tool for the automatic generation of mappings. - write a nice setup routine which will make it easyer to get the server running. - publish additional mappings for commonly used wikis, blogs and CMSs in order to speed up the creation of public SPARQL endpoints. So if anybody knows about related work or wants to contribute ideas to any of the topics, everything is welcome. Christian Lehmann (University Leipzig) is working on a D2RQ imlementation in PHP. It would be great to be able to use D2RQ in PHP applications and we hope to integrate his code into our RAP - RDF API for PHP. Who of you is attending ESWC? What about a BOF meeting on Tuesday?
