The
Open Healthcare Framework (OHF) Project is using the IHE/XDS secure document server developed by NIST using the ebXML Registry OMAR open source implementation - (http://www.freebxml.org).
At the recent IHE connectathon and HIMSS showcase the OHF team demonstrated a full XDS system, end to end. The XDS system includes XDS Registry, Repository, PIX server, ATNA, and all related clients - Document Consumer, Source, PIX/PDQ, CT. and ATNA.
The project includes collaboration between IBM, BEA, Mayo Clinic, Cisco Systems and other clinical participants.
