[tdwg-tag] Specimen identifiers

[Matt Jones]

Thought you all might be interested in a parallel universe, in which the
Code4Lib community is also discussing this issue of shared identifiers,
resolvability, and persistence at the same time as TDWG.  Here's one
particularly related message in that thread....

Jonathan makes some good points about the importance of shared identifiers,
and some interesting remarks about whether expressing these in RDF really
helps at all.
