In this article, we will describe the rationale behind our new service, Greycite, that we have developed in general enable more formal citation of URLs, and specifically to back up the kcite citation engine.

I have a PhD studentship available for anyone wishing to work on using the Semantic Web and linked data to improve the process of scientific publishing.

In my previous articles, I have talked about general problems with DOIs (n.d.a/) about architectural issues with capturing metadata (n.d.b/) and finally, about specific problem DOIs (n.d.c)

In this article, I consider the problems of semantics-free identifiers in OWL and suggest another (possible) solution to the problem.

Previously, I described the additions that we have made to the kcite plugin (n.d.a/) which now supports multiple different types of identifiers. This includes the subset of DOIs (n.d.b/) that come from either CrossRef (n.d.c) or DataCite (n.d.d) arXiv (n.d.e/) or Pubmed (n.d.f/) However, rather embarrasingly, one of the identifiers that we do not support well are URLs. Slightly ironic as one of the purposes behind (n.d.g/) is to demonstrate that it is possible to replicate the publication experience using the web.
