Re: FHIR server implementation having a RDF triplestore

Hi Daniel,
I have a need for a native RDF store with FHIR capability too and have been
looking for the past few months but with no luck. We may just have to build
one. :)

If the need is only for FHIR Terminology, you can try Ontoserver
<https://ontoserver.csiro.au/> - has a FHIR endpoint and can load OWL files
(after converting to a FHIR resource). It does not have SPARQL capability
however. And it is a commercial product.

If we do end up building one, it will probably be a knowledge platform with
separate stores internally - one for FHIR (something like HAPI/RDBMS?) and
a separate triple store for Ontologies and RDF data, and keeping the data
synchronized between the two stores to the extent possible.

cheers
Sivaram
