Nice. That enumerates the choices, I think. In a world where the services are themselves being used as LD URIs (because everything is a LD URI, of course!) there is the orthogonal question of whether the URI needs to be URLEncoded. And in fact I think all the prefixing patterns fail that test?

Hi, I documented all the variations of this form of URI construction I was aware of in the Rebased URI pattern: http://patterns.dataincubator.org/book/rebased-uri.html This covers generating one URI from another. What that new URI returns is a separate concern. Cheers, L. On Fri, Aug 22,

Hi Mark, Indeed. Interestingly, this use case was the first one I published as an example of RDF Forms; http://www.markbaker.ca/2003/10/UriProxy/ It's then probably not a coincidence that the first iteration of triple pattern fragments worked with the RDF Forms vocabulary :-)

Hi Luca, I'm wondering however if *form URIs* could themselves be resources rather than datasets. Sure, why not. They're just URIs. For example imagine the example from earlier: http://bar.com/?subject=http%3A%2F%2Ffoo.com%2Falice a void:Dataset . http://foo.com/alice #some #data .

bnodes are Semantic Web, but not Linked Data. If a node doesn't have a universal identifier, it cannot be addressed. I find this comment strange. If you mean that I can’t query using a bnode, then sure. If you mean that I never get any bnodes back as a result of a Linked Data URI GET, then

One of the advantages of bNodes is that they don't have names so that people can't add things to them. This is useful in the case of RDF Collections and in places of the OWL spec where you can use them to say that 'these things are in the collection' and others can't add to them. On Mon, Aug

Hey all, the only specification I know that actually solves practical RDF input problems is RDF/POST encoding: http://www.lsrn.org/semweb/rdfpost.html It can be easily incorporated into XSLT stylesheets to provide reusable layout templates, and with SPIN constraints to provide validation:
