Re: FHIR server implementation having a RDF triplestore

Dear Vladimir, thank you for your answer.
My question is not really to know the implementations of RDF triplestores,
but rather if there are implementation of a FHIR server using a RDF
triplestore as database layer?

For example HAPI FHIR uses JPA and stores the resources as a CLOB in a
database supporting JPA so mainly RDBMS (MySQL, PostgreSQL, Oracle..) and
the resource is encoded in JSON in one single column.
Aysmmetrik FHIR server uses mongo:
https://github.com/Asymmetrik/node-fhir-server-mongo

But I can't find a an implementation of a FHIR server that stores the FHIR
TTL in a RDF triplestore...
So my question is, is there an impementation (like HAPI , Aysmmetrik,
Firely...) that uses really FHIR RDF natively in a RDF triplestore.
