Ping @thomas.beale any news on this from e.g. Graphite?

After a demo of [openFHIR](https://open-fhir.com/) 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](https://build.fhir.org/genomicstudy.html) 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](https://discourse.openehr.org/t/ehrs-with-different-system-id-in-the-same-server/3535/37)
