Yes. I don't expect it to scale like EOR or other RDF DB backed toolkits, but it was quick an easy way to prototype some of these ideas and offer an another independant demonstration of the benefits for the DCMI community to declare terms in a consistent and systematic manner. A bit more on Redfoot: [[ Redfoot is a framework for building distributed data-driven web applications with RDF and Python. It is being developed by James Tauber and Daniel Krech. It can be used to develop personal or workgroup information environments, community web sites or any kind of web application that involves managing the relationships between different information objects in a consistent yet extensible manner. Redfoot includes: - in-memory RDF database - RDF parser and serializer - query API - templating language for building RDF-driven web-sites - reusable module architecture and sample modules (including schema-driven RDF editor module and RSS viewer module) - beginnings of a peer-to-peer architecture for communication between Redfeet ]] -- http://redfoot.sourceforge.net/ Add a back-end RDF Database and change the programming language to Java and it sounds a lot like EOR :) >I still think we should add the isRefinedBy propertie(s) to elements that >have refinements.

It is even more important with RDF since you >don't have the data (in columns) to build indexes on. I would suggest not focusing on adding any additional information to the schema. The redfoot prototype http://potlach.org:8000/ demonstrates how one can infer isRefinedBy properties to elements that have refinements. I would much rather focus on making sure the schemas are accurate and up-to-date. Additionally, I'd suggest focusing on encouraging the DCMI community to begin to declare human readable labels and descriptions in multiple languages in the same consistent and systematic manner. Registry and navigation tools are only as good as the data, unfortunately we seem to have very little data to navigate. -- eric miller http://www.w3.org/people/em/ semantic web activity lead mailto:[log in to unmask] w3c world wide web consortium tel:1.614.763.1100 200 technology square, ne43-350 fax:1.208.330.5213 cambridge, ma 02139 usa
