RE: Expressing XLink concepts in XML Schema
Hi James, James said: Actually, there seems to be a lot of conceptual overlap between XLink and the RDF model/syntax. Didier says: This is because some are stretching too much the utility of RDF. At its origin, RDF has been designed as a metadata encoding tool. This is why you have the following construct <rdf:description about="http://www.netfolder.com/index.html"> ... put here a set of properties/values like for instance the Dublin core or AGLS record... </rdf:description> So, on one hand you have the resource located somewhere and on the other hand, metadata providing more info about the resource. Xlink, is designed to link resources thus, for instance, to establish a link between a document fragment and an other document fragment. We have here, in fact, resource linkage. So, if we do not do like kids that received a do-it-yourself kit for Christmas and start a quest for nails for our brand new hammer, we can use the tool for what they where intended to - which is: a) rdf for metadata - to add information to existing resources b) xlink for resource linkage - to link resources This said, we'll have more and more similarities because: a) all these languages are XML based, b) we start to see now some common sub languages used across different tools like for instance XPath and XPointer (re-united) and the string based pointer language used in other XML based languages. James said: Also between XML Schemas and RDF Schemas. Didier says: Yes and this is good news because having a single schema language is more intelligent than having to still live in the Babel tower. regards Didier PH Martin mailto:martind@n... http://www.netfolder.com xml-dev: A list for W3C XML Developers.
