[tdwg-guid] First step in implementing LSIDs

The main use of the LSID http proxy would be when you have an RDF document or a triple store full of data that has BOTH the LSID and the http version (as described on the wiki page http://wiki.tdwg.org/twiki/bin/view/GUID/LsidHttpProxyUsageRecommendation).
If ALL you had was the LSID "URN:LSID:landcareresearch.co.nz:Names:0F9D60F1-59C7-495D-A37E-09C23770DD18" and no other data at all, and you want to resolve it using the http proxy, then yes you are a bit stuck (as far as I know).  Unless we set up an LSID http proxy repository that can be queried and returns the http proxy url for an LSID?  Or you could just use the "hard coded" http proxy resolver at http:/lsid.tdwg.org/[lsid].

I think the problem is that, without me telling my software something I have
gathered from this email, my software has no means to know about what you
describe as easy.

Unless it has an LSID resolver, in which case it would not need the http

This is what the proposal to always use alternating http and LSID guids in any
object we communicate about is saying. Whenever you publish
URN:LSID:landcareresearch.co.nz:Names:0F9D60F1-59C7-495D-A37E-09C23770DD18 you
also have to provide the http version of it.
