If you add UID on ENTRY level and you want to use that for some referencing/look up functionality: How do you handle versioning of Compositions and its content? Is it a new entry UID for each version ?
Here are description on some functions we have added to DIPS Arena EHR Server to make it simpler/more convenient to work with addressing LOCATABLES. To make it simple for client application to access the unique reference to LOCATABLE we have added the function ehr-uri(<LOCATABLE>) to the AQL query syntax. One example may be: select ehr-uri(o) as EHRUri, o/data[at0002]/origin/value as Time, o/data[at0002]/events[at0003]/data[at0001]/items[at0004]/value/magnitude as Weight, o/data[at0002]/events[at0003]/data[at0001]/items[at0004]/value/units as Unit FROM COMPOSITION c contains observation o[openEHR-EHR-OBSERVATION.body_weight.v1] order by o/data[at0002]/origin/value desc limit 5 One example of the ehr-uri may be: ehr:compositions/131b9960-a2b0-452b-a140-34990dd3487d::9624982A-9F42-41A5-9318-AE13D5F5031F::1/content[openEHR-EHR-OBSERVATION.body_weight.v1 and name/value='Body weight_001'] And then when you want to get the resource defined by the EHR-URI we have added a simple LINK endpoint. This looks like this: <host>/api/v1/link?ehruri=ehr%3Acompositions%2F131b9960-a2b0-452b-a140-34990dd3487d%3A%3A9624982A-9F42-41A5-9318-AE13D5F5031F%3A%3A1%2Fcontent%5BopenEHR-EHR-OBSERVATION.body_weight.v1%20and%20name%2Fvalue%3D'Body%20weight_001'%5D Vennlig hilsen Bjørn Næss Produktansvarlig DIPS ASA Mobil +47 93 43 29 10 -----Opprinnelig melding----- Fra: openEHR-technical [mailto:openehr-technical-boun...@lists.openehr.org] På vegne av Pieter Bos Sendt: tirsdag 13. desember 2016 14.42 Til: For openEHR technical discussions <openehr-technical@lists.openehr.org> Emne: Re: Could the specs group consider making uid mandatory?
