Hi Best Practices/Deployment folks, You might have seen our recent WD... RDF Data Access Use Cases and Requirements W3C Working Draft 2 August 2004 This Version: http://www.w3.org/TR/2004/WD-rdf-dawg-uc-20040802/ Latest Version: http://www.w3.org/TR/rdf-dawg-uc/ This is our 2nd release; in the Status section, note "the design objectives are in development. The status of each design objective indicates whether it has been adopted by the WG. The requirements have all been accepted by the working group." While the BPDWG is more than welcome to review the whole document, either individually or as a group, we're particularly interested in feedback on a couple things: 1. XQuery, syntax and integration: We're chartered to "... maximize W3C technology re-use, while also taking account of differences between the RDF graph data model and the XQuery data model" and to allow "... for RDF data to be accessable within an XML Query context". -- http://www.w3.org/2003/12/swa/dawg-charter#XQueryBinding We have been discussing an objective regarding making RDF data available in an XML Query context, http://www.w3.org/2001/sw/DataAccess/ftf2#qrdesigns http://www.w3.org/2001/sw/DataAccess/ftf2#xqfa but we don't have a critical mass around any particular objective yet. We have a "human-friendly syntax" objective http://www.w3.org/TR/rdf-dawg-uc/#d4.1 and there has been discussion of whether borrowing from XQuery syntax helps there. Anybody have experience with XQuery/RDF integration to share? 2. Rules, Additional Semantic Information We have an objective "It should be possible for knowledge encoded in other semantic languages—for example: RDFS, OWL, and SWRL—to affect the results of queries executed against RDF graphs." -- http://www.w3.org/TR/rdf-dawg-uc/#d4.6 and in discussion of rules and query http://www.w3.org/2001/sw/DataAccess/ftf2#qrdesigns we noted a connection between rules and a CONSTRUCT mechanism found in various contemporary designs, including our current draft http://www.w3.org/2001/sw/DataAccess/rq23/#construct $Revision: 1.25 $ of $Date: 2004/08/16 12:23:00 $ Any rules/query integration experience to share? Thoughts on best practices for accessing RDF data, while rules work is still in the early stages of standardization? -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
