Specifications, 1998 to 2003
The Open Healthcare Group's specifications, reference documents, software and talks from the XML era, kept here as published. Links go to the original documents, and some of them show their age. Parts of this work were later incorporated into FHIR and the XML representation of DICOM; the current work is on the projects page.
