OSEHRA AWG WG Slide Deck & Follow Ups for 12/4

 

Hi -

I've attached our slide deck for those interested.

  • Christopher Edwards made a great recommendation to provide an installable MDWS rather than having a developer compile from source. - we can do this if its of interest to anyone - just speak up.
  • As discussed on the call - if folks would like a run through on enhancing MDWS just let us know ahead of time and we'll gladly go through a sample during one of our Friday calls..

Best regards,

Chris

Mastering Medical Concepts by Conor Dowling

During the November 27th Architecture Work Group Meeting, Conor Dowling of Caregraf presented "Mastering Medical Concepts" from the perspectives of :

- Medical Concepts in a standard SKOS/Linked-Data service

- Handling unproductive variety (overlay vs 'back the best')

- Federating with new concept data and patient data

The Simple Knowledge Organization System (SKOS) is a common data model for sharing and linking knowledge organization systems via the Semantic Web.

Rob has presented what he believes to be a significant improvement to the MDWS.  Moreover, the openMDWS services can be made available over HTTP from any GT.M/Cache VistA server directly.
