Perhaps I'm misunderstanding the specific needs here, but I wonder if authoritative identification of individuals is really an argument for a ID-oriented naming convention - such as LSID. I have a better understanding (than I did before) of what drives the need for LSID's from the ongoing discussions, but it's worth mentioning that the mechanics of InverseFunctionalProperties (which FOAF uses) can provide a means to identify individuals uniquely. If you label a role/property as being inverse functional then you are saying it can only be used on *one* individual. Explicitely: {?P a owl:InverseFunctionalProperty. ?X ?P ?O. ?Y ?P ?O} => {?X owl:sameAs ?Y}. As long as your vocabulary has such identifying roles/properties (FOAF uses the persons email address, but it could be any centrally managed system-wide identifier - I'm certain most institutions have this) you can very easily enable identity reasoning > This is why we'd started investigating LSID over a year ago, as we need an ID > franking authority at least at the subject and or biomaterial sample level. > To be honest, I think we've only partly solved this problem, to the extent > required to pass animals back-n-forth, and so far we've been using a > propriotary authority, which will later need to be mapped to some more global > authentication service, possibly LSID-based, or whatever becomes the "best > practice" as recommended by the BioRDF group. > > Cheers, > Bill Chimezie Ogbuji Lead Systems Analyst Thoracic and Cardiovascular Surgery Cleveland Clinic Foundation 9500 Euclid Avenue/ W26 Cleveland, Ohio 44195 Office: (216)444-8593 ogbujic@ccf.org
