RDFx allows for fields to be expressed as RDFa. Sometimes RDF concepts exist in other locations, for example DBpedia, and not as part of the local taxonomies. What is the recommended way to link to these external resources? These resources do have persistent URIs, so I guess the simplest thing to do is to make the field into a link. But ideally one would prefer to get a good label to show on the HTML output rather than the link itself. RDF Proxy (http://drupal.org/project/rdfproxy) seems to be doing that but the project appears to be abandoned. Any ideas?
