Points we've been considering are whether to use @profile to import these mappings, whether RDFa should be used to describe the mappings, whether we should map tokens to URIs, or relative paths to URIs, whether to use OWL, and so on. All of this is still being discussed. Speaking only for myself, I'd like to see us come up with a technique that works in the browser -- which has consequences for the technology used. Although it's quite easy to 'import' an external RDFa document, and import the triples contained within it, you can only do this if the external document comes from the same domain as the host document. (Importing simply consists of using a hidden iframe.) So to be able to import mappings from a central site -- say Yahoo! or Google wanted to make mappings available for their vocabularies -- we'd need to be able to use some kind of JSON-based format. Anyway...as you can see, there are a lot of factors to take into account. :) Regards, Mark -- Mark Birbeck, webBackplane mark.birbeck@webBackplane.com http://webBackplane.com/mark-birbeck webBackplane is a trading name of Backplane Ltd.
