Great discussion in the meeting today and on the email list: BRIDG/OWL, FHIR/SW, Extensional and Intensional /" design-time" and "run-time" models, ... a lot of interesting things seems to converge for how to model patient data.
At the same time I think it would be useful to explore a RDF implementation of today's CDISC SDTM domains (and Supplement Qualifier) data structures. That is,RDF triples and as an alt. to ODM/XML for data exchange. So far my focus has been on pushing CDISC, and NCI, towards "Linked Clinical Data Standards", see http://kerfors.blogspot.se/2012/05/semantic-models-for-cdisc-based.html, as a prereq. to be able to get to "Linked Clinical Data" Kind Regards Kerstin
