XSchema Question 1: RDF
How will XSchema use/relate to RDF? There are several options I can see: 1) XSchema could be designed, top-to-bottom, as an RDF application. This wouldn't necessarily rule out defining XSchema in its own terms with an XSchema document or providing a DTD, but it would require that participants have significant working knowledge of RDF. On the bright side, I suspect the W3C would look more kindly on an RDF implementation, if we can make it work. 2) XSchema could use RDF for the descriptive information contained in XSchema documents, but use its own model for defining elements and attributes. 3) XSchema could ignore RDF altogether. This wouldn't rule out the use of RDF to provide metadata information about documents, but would leave RDF out of the structural information included in XSchema documents. 4) XSchema could allow the use of RDF as one of many ways to extend the schema information provided. I'm still conducting my own full-scale investigation of RDF. I'm very concerned about several issues: 1) I don't want this discussion limited to the relatively small number of people who have figured out RDF. 2) I don't want XSchema to need to make drastic changes if RDF moves suddenly - it isn't complete. (From what little I've heard, this doesn't sound likely.) 3) I don't want readers of the XSchema spec to have to bounce between it, the RDF spec, and the XML spec to figure out what's going on. Rigorous definitely made it into the goals, but readable and clear remains an important target. Making RDF useful for this project, if we choose to use it, is going to require the creation of a much fuller set of tutorials in particular. The current set (listed below) is notable for its density and its lack of concrete examples. I'm willing to work on this project (I may even be able to get paid for some of it) if we decide that RDF is important. I'd also like to hear about other resources already in existence. Current Useful Resources: http://www.w3.org/TR/NOTE-rdf-simple-intro - A 'lighter' intro to RDF http://www.w3.org/TR/WD-rdf-syntax/ - RDF Spec, current draft http://www.dlib.org/dlib/may98/miller/05miller.html - "An Introduction to the Resource Description Framework" This is a very large and difficult question, one which directly impacts the rest of the work. I'd like to see us frame an answer within a week, so that we can move on to implementation. As a consensus develops, I'll see what I can put into writing.
