In its 1.1 release, FMQL will move its JSON format over to JSON-LD. This form of JSON provides a straightforward JSON with rigorous semantics, something key for VistA data with its large and powerful data model.
By following the installation instruction of the Fileman 22.2 submission in OSEHRA Technique Journel (http://code.osehra.org/journal/browse/publication/27), we install Fileman 22.2 sucessfully on a VistA instance based on FOIA 082412 release. Routine changes are extracted and imported into VistA-FOIA git repository based on FOIA 082412. The difference between Fileman 22.2 and FOIA 082412 can be view directly via github:
The Fileman 22.0 documentation suite, as released by VA, included: Release Notes, Installation Guide, Technical Manual, Getting Started Manual, Advanced User Manual, and Programmer Manual.
We're in the process now of revising the documentation suite for the 22.2 release. We have completed the Release Notes, and I believe that the current draft has been uploaded to the "Documents" section of this project. (It is a "current draft" because we haven't yet received VA approval for it.)
For a while now, you've been able to extract any data - Patient, Institution, Knowhow or System - from any VistA using FMQL, the FileMan Query Language. Open source FMQL projects FileMan as a "web of data" - it's based on SPARQL, the w3c's semantic web language - and to it, data is just data with all of VistA's 2500+ files treated the same way. This contrasts with the myriad of "data type specific" extractors VistA supports today.
I'd just like to point out two upgrades in progress.
Not just JSON - RDF and HTML too
