<renato> is there a webex URL for this meeting?

<Lena> https://deri.webex.com/deri/e.php?AT=WMI&EventID=221308912&PW=ba46734c575b5e5216131004&RT=MTgjMjE%3D

<Lena> sorry, was distracted :)

<renato> Yes, audio not too clear!

<renato> (sorry, just reconnected to call after dropping the line)

Charlie: HL7 doesn't have much SemWeb expertise in the organization. Despite not knowing that much about SemWeb, it seems to me that SemWeb should be taken up by standards organizations.
... HL7 now grappling with the lack of take up of v3.
... FHIR is a new development. Charlie and Eric are engaging them, such as at the May meeting.
... FHIR (pronounced "fire"). Eric and Charlie have spent some time working out representations of FHIR resources in RDF and OWL. FHIR Dev team is now interested in continuing the work.
... HL7 has funded a complete OWL representation of RIM, HL7 data types, and value set bindings / mngmt. Lloyd MacKenzie has worked on this, esp. the RDF with Eric.
... Would like to see FDA take up of these developments.
... Ratnesh - you apparently have done your PhD work in this area.

Ratnesh: How much of the work is done?

Charlie: Eric gets most of the credit. There's plenty to do still.
... Ratnesh - could you come to a meeting in Sept?

Lena: Does it make sense to write up a white paper based on FHIR / Ratnesh / etc.?

Charlie: Yes.
... CDISC and HL7 have fairly strong ties, including Karen XXX? (from CDISC) who sits on the HL7 board.
... Eric, Lloyd, Cecil Lynch, and I will be there.

Scott: (disclaimer: haven't read entire chapter) There seems to be a balance to be struck between OWL modeling (an ontology as knowledgebase) vs. some light-weight modeling using RDF and SPARQL (EricP prefers this).

Charlie: I worked with EricP on a Lab RMIM representation intensively and we came to the conclusion that OWL is good for modeling and RDF/SPARQL is good for much of the run-time stuff - partly because of the wide availability / interoperability at that level.

Kerstin: In AZ, we've been trying to push CDISC in the SemWeb direction. I've presented on this at the last two CDISC meetings. Another thing to do is to push NCI Thesaurus toward SemWeb.
... The OWL representation of BRIDG has been distributed to me and a colleauge. It was good to hear that Eric is closely involved in all this.
... Could be very important opportunity to bring this to the FDA in November.

Charlie: I think that Wayne (@CDISC?) will respond well to seeing specific examples of SemWeb representations of known CDISC / HL7 artifacts, such as what is happening in FHIR.
... Wayne just joined the BRIDG board of directors.
... Lloyd was hired by NCI to create a BRIDG-RIM map, which he did without SemWeb. He says he would use SemWeb to do it next time.

<ratnesh> in the book chapter (A Formal Investigation of Semantic Interoperability of HCLS Systems) sent two days back to the list: I have discussed problem caused due to global resources and local resources. How inconsistencies arise from local and global ontologies and their alignment. Problem of local constraints highlighted as well and a solution path discussed. All this is discussed using example from the HL7 Version 3.

Charlie: NCI has cut drastically recently but seems receptive to SemWeb infrastructure projects.
