<mscottm> Hi, anybody here? I can't hear anyone on hcls2
<mscottm> scott: brings up serving UMLS terms from a different location than UMLS, would it be possible?
<mscottm> harold: I've looked into this type of thing for some time in the context of HL7
<mscottm> ..NLM thinks it would require 'semantic lifting' although I'm not entirely convinced
<mscottm> ..example: take 'cabernet sauvignon' from wine ontology, remove namespace and replace it with PURL namespace of bioportal
<johnM> Hi all I will be back on momentarily
<mscottm> http://sharedterm/snomedct/1234567
<mscottm> http://sharedterm/umls/12345678
<mscottm> two issues: 1) using the same URI 2) providing RDF when you resolve that URI
urn: iso:2.16.840.1.113883.6.92:12345678
URI to cannonical URI: f(urn:iso:2.16.840.1.1138836.92) --> http://sharedterm.org/snocmetct/1234567
f(http://sharedterm.org/snomedct/1234567) --> http://sharedterm.org/snomedct/1234567
f(http://sharedterm.org/snomedct/) --> http://sharedterm.org/snomedct/
the challenge is the "1234567"
Two issues: (1) there are many URI's for 1234567 in SNOMED and (2) there are multiple renderings for SNOMDE 1234567
(1) Someone need a map from many URI's to a (contextual) cannonical URI
(e.g. http://purlz.og/sct/)
What this allows is, instead of telling HL7 "your URI's are no good", we say - use this URL and we will return the source (e.g. IHTSDO) URI, which you can then use on the web
Use the URL (purlz.org/uri/urn:iso:216.840.1.113883.6.92) to the http://ihtsdo.org/
or http://purlz.org/uri/http://ihtsdo.org/ --> http://ihtsdo.org/
<mscottm> http://esw.w3.org/topic/HCLS/CSHALS2010/Tutorial#outline
Actually, what I would hope happens is that http://purlz.org/uri/urn:iso:2.16.840.1.113883.6.92 --> http://purlz.org/ontology/ which, in turn, dereferences to the appropriate RDF or other resources....
<mscottm> harold: CDM is a metadata interchange format for clinical trial data from CDISC (there's another CDM too..)
<mscottm> NCBO is looking at the type of RDF that they will serve, looking at SKOS..
Also, CTS2 is looking at SKOS/RDF rendering of the LexGrid rendering of UMLS, SNOMED, etc.
So that is another path that may acutally work slightly better than each community coming up with their own RDF
We are working with Nigam and Natasha on this as well.
NCBO == Stanford + Mayo
<mscottm> great!
