My concern is that the choice of LSIDs is based on too narrow a system view.
The true system includes biologists, public administrators, other experts, and
many kinds on non-LSID-aware software.
Scenario 1: Taxonomist publishes a paper in printed or online journal. Do I use
the LSID, knowing no other biologists can interpret this, or do I use the http-
GUID, which every biologist reading the paper can follow and retrieve some
Scenario 2: I create a html-based web page for a species account. I could use
the lsid as visible id, with the implications above. However, I would certainly
like to support my users by linking to the resource and use the http as the
link behind the text. From this moment on, for Google and all current other
information indexers, the http-URL (which is always a GUID) will become the
preferred ID under which this resource can be accessed.
What is the public usability of the GUID system that we plan?
The desired fall-back safety of Ricardo's scenario:
> <rdf:Description rdf:about="urn:lsid:ubio.org:namebank:11815">
> rdf:resource="http://lsid.tdwg.org/urn:lsid:ubio.org:namebank:11815" />
can easily be achieved without the overhead of LSIDs, by using:
Several commentators have mentioned that http-GUIDs have a problem if the
resource disappears. I believe this is only true with respect to resolving the
GUID. The GUID functionality itself is unaffected if the DNS entry disappears.
If ubio disappears, the GUID http://lsid.ubio.org/namebank/11815 can still be
used for centuries. The service that resolves may already be published in RDF
metadata (through SameAs), or it may be built into some systems.
*** Using something like "bio-id.org" (i.e. registering a new DNS, but running
it through existing ifnrastructure (preferably GBIF) would improve future
flexibility on who might pick it up, if something happens to tdwg or gbif. ***
