Re: [architecture] A Proposal to create a Universal Namespace for Health Information Architectures

to go narrow for a moment, giving every resource of every EHR a unique URL makes all the sense in the world and remember, current HIE specs overlay unique ids on those portions of EHR data that go into CCDs. Each publisher has a unique id and the contents of their documents are unique in this context. The main problem with the "standard" mechanism is that it uses OIDs ( Oy Vey OIDs! ) Why use a technology last seen as promising in 1992 when you can use URLs? To scope up to part of what Tom is addressing: give every VistA resource a URL and that's what I did/had to do in FMQL. Every VistA instance gets a unique base URL (ex/ vista.caregraf.org ) and once inside VistA, files establish context (file 2 is Patient so http://vista.caregraf.org/2 ) and their contents have unique ids (IENs) so record 9 in file 2 is , the 301ist Vital Measurement is ... This scales and it's unambiguous. Addressing and identifying information from an additional VistA (or EHR) is easy - just add a new base URL (vista.va.gov/boston1/ , vista.va.gov/westla_test/ ...) You could say URLs liberate data, establishing each piece as a standalone entity. If you think about it, nothing properly exists without identity. Two asides: - if you move things: newvista.../2-9 owl:sameAs http://vista.caregraf.org/2-9 ... - "same concept in two vistas": http://vista.caregraf.org/50-10 owl:sameas anothervista/50-55 As for being within OSEHRA's scope: if you want to document all the VistAs running and converge their code bases, then identifying each unambiguously is a good start. If you want to document where they differ, then identifying their content unambiguously is mandatory. You can't compare and contrast without identity. I realize that the VA is reluctant to publish the setup of their VistAs though that would be a great step forward for all: were there to be a place for identifying these setups, a base URL assigned by OSEHRA then maybe ...
