During data integration or "data reuse", we have to relate

identifier to refer to the same 'biothing'. We would also like our
statements to remain true (based on the 'biothings' and their
relations at the moment the statement was made, even if some
aspect of the data evolves (physical storage location, new
results, new relations, etc.).
For integrating "biothings", http://purl.uniprot.org/uniprot/P12345
should be perfect! The main discussion at the moment is how much of
a benefit there is in having a PURL for a specific representation
such as the web page for P12345, in addition to the PURL for the
"biothing" P12345.
Im really only lurking here, but reading this, an obvious strategy
seems to be to use PURLs for biothings and non-PURL URIs for Webbish
things like Web pages. PURL for a Web page seems like overkill anyway.

I'll also add support for identifiers with version numbers, e.g.
http://purl.uniprot.org/uniprot/P12345.2, which should resolve to
http://beta.uniprot.org/uniprot/P12345?version=2, though most of
our data is not versioned, and there is no explicit syntax for
versioning, either.
