RDF for Semantic Interoperability

Return to ITS Main Page | ITS RDF Minutes 2014 | All ITS RDF Pages | ITS Email Archives | W3C HCLS Email Archives | Issues List

The RDF for Semantic Interoperability group (or RDF group) is a sub-group of the HL7 ITS work group and a joint collaboration with the W3C Healthcare and Life Sciences group on Clinical Observations Interoperability to facilitate the use of RDF as a common semantic foundation for healthcare information interoperability.

How to Participate

Anyone may join this group simply by participating in the work, which is conducted mainly on the public HL7 and W3C mailing lists listed below and on a weekly teleconference. You are encouraged to become an HL7 member, but not required unless you wish to take a leadership role in an HL7 group, such as becoming a co-chair. You are also encouraged to have your organization become a W3C member, but not required. See benefits of W3C membership.

ICD-11 and SNOMED

Champions: Tony Mallia, Daniel Karlsson, Hans Cools

• ACTION: Tony to find out more details about how iCat handles ICD-11 ont and report back [recorded in http://www.w3.org/2014/11/18-hcls-minutes.html#action01]

Use Cases

Champions: Guoqian Jiang, others? COI Use cases on W3C wiki

• ACTION: Guoqian to figure out whether he can share URI conventions for ICD-11 [recorded in http://www.w3.org/2014/11/25-hcls-minutes.html#action07]
• Discussion

Goals of use cases:

• Drive and unify diverse efforts, e.g., FHIR ontology

Kinds of use cases desired:

• Simple enough for use in slide presentations
• Realistic enough to be convincing

Use case ideas:

• Migration of CCDA to FHIR (EricP)
• Utility on FHIR RDF that would motivate mapping of FHIR XML to FHIR RDF (EricP)

Next Steps

• EricP will present C-CDA example on Dec 23.
• Waiting for Guoqian for broader discussion of use cases.

PhUSE-FDA project (formerly CDISC2RDF)

Champions: Kerstin_Forsberg, Ingeborg, Tim Williams, (and Charlie Mead?)

• ACTION: Kerstin and Ingeborg to prepare a status and future state ideas for PhUSE-FDA work [recorded in http://www.w3.org/2014/11/18-hcls-minutes.html#action05]
• Discussion

Next Steps

• DBooth scheduled @@@@ to discuss PhUSE-FDA project on Jan 6 teleconference.

Champions: Eric Prud'hommeaux, Joshua Phillips

• ACTION: Eric to establish/make a wiki page for C-CDA RDF representations work [recorded in http://www.w3.org/2014/11/18-hcls-minutes.html#action06]
• ACTION: Eric and Joshua to report on C-CDA RDF representations work plan [recorded in http://www.w3.org/2014/11/18-hcls-minutes.html#action07] -- PENDING? (On Dec 16 call I thought Eric said this was done pending review, but I cannot seem to find it.)
