Ping @thomas.beale any news on this from e.g. Graphite?
After a demo of openFHIR today I would very much like to have something like the “Registry” (extended from Demographics) in openEHR so that we could properly model and long-time store stuff that is often exchanged using FHIR.
An example is stuff in and related to GenomicStudy - FHIR v6.0.0-ballot2 that we want to use and store for Precision Medicine, over time surviving major FHIR version updates and be able to serve both using V4 (using a hack) and V6.
Of course some more general graph querying language than AQL would also be needed for Registry - best would be if it could cross-query the EHRs and Registry in the same optimized queries. See hints about AGQL in e.g. EHRs with different system_id in the same server? - #37 by erik.sundvall
