Today I looked at the OpenEhr API: https://www.openehr.org/releases/ITS/latest/ehr_restapi.html#top
I live sometime in the OpenEhr world, so I am not surprised that it is a rather low level API. In fact it is a bit hard to recognize quick what it is about. And it fits perfectly to the philosophy of OpenEhr. The API is not semantically rich. It are the archetypes which are semantically rich, the API IS GENERIC. So it is fine. I am not criticizing. I found another API on the Internet, in fact, I found many. They are all semantically rich. They all have functions like "Which medication does the patient take". In OpenEhr there is only a function to execute a query to find semantically meaningful data. The API itself offers no further clues. Again, this is not criticizing, it fits in the philosophy of OpenEhr. It is impossible to write queries for the customers, because we do not know the archetypes they use. The customer is helpless without the expertise of OpenEhr specialists, of which are not many people on the world. I think, from marketing point of view this is hard to sell, because other vendors offer semantically rich API's out of the box. Only a web developer, without special education is then needed to write a GUI. I think it is not necessary that it is that way. The premise that we don't know which archetypes customers use is not always true. In fact, from many customers it is known that they use archetypes from CKM. So, my point: How nice would it be when CKM would publicly be extended with queries which fit on the archetypes, which can be used to create a semantically rich API. This would have to advantages. 1) It would be a strong marketing point. An OpenEhr customer would not anymore need expensive expertise to do simple things like querying which medication a patient uses. 2) It would motivate customers to use CKM archetypes (Which maybe do not use them now, or edit them without telling anyone, and maybe even without changing the identifier) because this would then have an extra advantage to stay closely connected to CKM. Someone having any thoughts about this? Bert
