Richard's exactly right, and there's a very nice lightweight (and registered!) URI scheme that would work for this purpose, namely tag: - http://www.ietf.org/rfc/rfc4151.txt I think that would serve well here. You just need an install step for any software generating these things that provides it with a suitable collision-avoiding prefix (email address or domain name). Then it can use a combination of time and spin count to generate these URIs. You'd want to review the security implications, but they're probably not too bad. If you're worried about turning them back into bnodes on reading in a graph, then perhaps a new URI scheme registration is needed, or maybe a special convention for use of tag: can be agreed on. Interesting problem.
