Work projects
• Current:– FHIR ontology
– PhUSE-FDA project (formerly CDISC2RDF)
• Proposed:– Bridging VA, Intermountain and other models
– Use Cases
– ICD-11 and SNOMED
– C-CDA RDF representations
– High-level concept mapping to RDF (AR typeCodes, etc.)

FHIR RDF / Ontology Deliverables
• Mappings between FHIR XML/JSON and FHIR RDF, for lossless conversion of FHIR instance data
• Ontology describing FHIR RDF
11
FHIR RDF / Ontology Status
• Requirements drafted
• Reviewed four independently developed approaches (Cecil Lynch, Josh Mandel & Eric Prud'hommeaux, Claude Nanjo, Tony Mallia)– Fifth approach also under consideration: JSON-LD
• Goal is to converge on a single approach, then standardize

• How can we be most effective?– How can we best support other groups
wanting to use RDF?– Collect RDF guidelines? E.g.:
