For comparison, here's an example of what you get from ckan.net + semantic.ckan.net: http://pastie.org/830693 At the moment we redirect into semantic.ckan.net from ckan.net via a rel=alternative and 303 on the Accept header, e.g try out: curl -L -H "Accept: application/rdf+xml" http://ckan.net/package/2000-us-census-rdf semantic.ckan.net also provides a human readable version of the data: <http://semantic.ckan.net/data/2000-us-census-rdf> We've thought quite a bit about integrating directly into ckan.net (hence the /data/ rather than /package/ on semantic.ckan.net) but the issue here is that we want to use a proper triple store for the data so you can query via sparql (currently http://semantic.ckan.net/sparql). Thus we've gone for the separate but related model for the present. Maybe it would be worth getting together for half-an-hour on skype and etherpad to work on hammering out a shared ontology here? I also know the people from DERI (Richard Cyganiak especially) are working on this so we should talk with them. > I have also made sure an Atom feed contains all datasets (with a link > element to the RDF representations in each entry element) here: > > http://www.opengov.se/feeds/data/ Great. Like you we should add RDF link to our atom feed (which as I've already mentioned can be found at http://www.ckan.net/revision/list?format=atom&days=30) > Please note that the feed contains datasets that are not (yet) open. > Some may have a commercial license and may not be available on the > web. That's also true for us ;) Regards, Rufus -- Open Knowledge Foundation Promoting Open Knowledge in a Digital Age http://www.okfn.org/ - http://blog.okfn.org/
