RE: [Fwd: Re: identifier to use]

There are a range of resources associated with TDWG's work on LSIDs over the
past 18 months. Some items have been mentioned previously but this posting
provides a brief context and an update.
 
There was a desperate need in the biodiversity informatics community for an
effective globally unique identifier. The TDWG Infrastructure Project
(http://www.tdwg.org/activities/tip/) sponsored two international meetings
to either adopt or develop an appropriate globally unique identifier for our
community. Both meetings endorsed LSIDs as an ideal technology. With
ontologies and transfer protocols, LSIDs now form one of the three
components of the new TDWG standards architecture.
 
 <http://www.tdwg.org/activities/guid/> http://www.tdwg.org/activities/guid/
maintains a comprehensive list of LSID-related resources. We are near to
completing an LSID Applicability Statement and an LSID Implementation Guide
for our community. A range of LSID 'vocabularies' for returned LSID returned
metadata have been developed at  http://rs.tdwg.org/ontology/voc/. These
vocabularies will be incorporated into the TDWG ontology.The TDWG annual
conference next month ( <http://www.tdwg.org/conference2007/)>
http://www.tdwg.org/conference2007/) will also be significant arena for
LSIDs for our community. 
 
I emailed OMG four times to ask about any work they were doing or planning
with LSIDs, and to let them know of our interest. I have not received a
reply. 
 
We had also heard recently that the LSID site on Sourceforge site was no
longer being supported. Consequently, we have setup a new Sourceforge site
at  <http://lsids.sourceforge.net/> http://lsids.sourceforge.net/ to ensure
ongoing access to LSID resources. 
 
I have also let ten contracts in the last year to aid the deployment and use
of LSIDs. We are assisting nomenclators and aggregators such as the
Catalogue of Life, IPNI, ZooBank and Index Fungorum to setup LSIDs and
associated resolvers. 
 
I hope some of this information may be useful.

Jonathan,

You probably already have this key DTC doc:
http://www.omg.org/docs/dtc/04-05-01.pdf

as well as: http://www.omg.org/docs/lifesci/03-01-06.txt (with a few use
cases), http://www.omg.org/docs/lifesci/03-09-07.txt,
http://www.omg.org/docs/lifesci/03-10-01.txt,
http://www.omg.org/docs/lifesci/03-11-05.txt,

Sean probably gave you this one as well:

I'm not as knowledgeable here as well, but have seen a few services around
DOI urns (see http://www.doi.org/press_release_archive.html)

One question I still have is how much of the basic infrastructure (global
web, intranet, SOA system, etc) needs to 'know' ahead of time that something
is not simply a string identifier but a URI entity, i.e., treat it as
something special and unique? Similar to the historic discussion about
symbols vs. strings? I've seen URIs or other identifiers referred to as
'merely strings that need interpretting'-- this need not be the case if the
lower parts of an information system are meant to handle them specially.
