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.
Mailing lists (please cross post to both):
Weekly Teleconference
Work Projects
FHIR RDF and Ontology
Champions: Claude Nanjo, Tony Mallia, Eric Prud'hommeaux, Marc Twagirumukiza, Hans Cools
FHIR RDF and Ontology work is being done both on our weekly Tuesday teleconference and on our Wednesday task force call: http://wiki.hl7.org/index.php?title=ITS_RDF_ConCall_Agenda
Deliverables and Editors
1. FHIR RDF page on the HL7 site, explaining FHIR RDF serialization (equivalent to existing FHIR XML and JSON pages)
Editors: Grahame Grieve
2. FHIR ontology explanation page, (TODO: Add link) explaining how FHIR structure definitions and other conformance resource can be expressed using OWL
Editors: Tony Mallia
3. Modify the supported reference implementations to consume/produce RDF, just as for XML and JSON.
Editors: (presumably the authors of the existing reference implementations, with help TBD)
4. Modify the FHIR spec build process, so when it produces JSON versions of everything and tests roundtripping, it also produces RDF versions of everything and tests roundtripping for RDF.
Editors: Lloyd McKenzie and Grahame Grieve? (to be confirmed)
5. Downloadable FHIR ontology (generated by the FHIR spec build process?)
Editors: (TBD - Grahame?)
6. ShEx implementation of FHIR XML<->RDF round tripping, for use as a reference implementation for the RDF reference implementations
Editors: Eric Prud'hommeaux (to be confirmed)
Background
- FHIR Ontology Requirements
- FHIR Examples For Driving FHIR Ontology Development
- Reviews of four FHIR ontology approaches:
- FHIR RDF Mapping - Potential Strategies
- FHIR RDF github page
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]
- Discussion

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.
C-CDA RDF representations
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.)
- Discussion
Next Steps
- EricP will present C-CDA example on Dec 23.

Standard URI Representations
- File:URI.pdf - Outline of URI approach presented to HL7 ~2012

- Guoqian Jaing and Eric Prud'hommeaux also discussed work at Mayo on a common model for data element management and value set binding, leveraging ISO 11179
- Eric also asked who else would be interested in a data Validation and Transformation task force, and three people indicated interest (Ingeborg, Alejandra, Kerstin_Forsberg).
