I’ve always been a fan of this part of the model, as it can really allow for quick integrations, but from chatting with everyone else, seems like I’m in the minority here
So I would like to propose a revamp for the model, not only in the model itself, but also in the use cases presented in the specification. Here is the tasks I proposed in the past to enhance the model:
SPECRM-18: Change GENERIC_ENTRY data attribute type from ITEM_TREE to the abstract ITEM class
SPECPR-297: Generic_entry would greatly benefit from a “meaning” attribute
SPECPR-296: Add FHIR example in Integration Information Model
If anyone has other suggestions feel free to discuss them. Probably last enhancement could be more interesting to have, so it shows what can be achieved with this.
As far as I know nobody is using this part of the model, so probably makes sense to improve it now before any implementation (EHRBase?) occurs.
Another argument in favor of its use is to bring some other communities into openEHR (thinking explicitly in the ISO13606 and HL7 CDA communities). This model can also be of pivotal importance in the new ISO 24305 of Guidelines for implementation of HL7/FHIR based on ISO 13940 and ISO 13606-3, as with little effort could probably make openEHR ISO 24305 compliant
