There's a lot to be said for keeping things very simple. Over in the biodiversity informatics community we've adopted Life Science Identifiers (LSID) as our identifier of choice, which require special software to both serve and resolve, plus the added complication of convincing your friendl

I am finding the current discussion really difficult. Those who do not learn from history are condemned to repeat it. As an example: In the 1980s there were a load of hypertext systems that required the users to do a bunch of stuff to buy into them. They had great theoretical bases, and their prop

DNS trickery is the ultimate step for a fully flexible architecture. Unfortunately it requires to have some admin rights over your own domain. Something uber difficult in companies. A workaround would be to create a top domain name, something like ..uris (or more realistically cooluris.net), with

Externalizing the 303 feature is the good idea, imo. But such a service should also handle the content negociation feature. So the 303 may redirect to different URLs depending on the content negociated. This makes the service more complex internally but provides a very relevant service for RDF pub

Hashed URIs can bring other problems. For example, if I have a service http://mydata.org/uri that takes a URI and returns what it knows about the thing identified by that URI and I pass it a hash URI, e.g. http://ci.nii.ac.jp/naid/110006281382#article , my browser will trim #article and send
