The Service Oriented Architecture (SOA) Working Group works to enable HL7 standards to be fully usable within systems that are designed using SOA principles. Further details of the SOA WG's remit and responsibilities are in its charter.

SOA WG is now moving to using Confluence for new content.

Please go to SOA Confluence Site

The SOA WG has an established working relationship with the OMG's Healthcare Domain Task Force (HDTF). Joint activities are conducted under the name Healthcare Services Specification Project (HSSP), with participation from both HL7 and OMG members. For convenience of administration and to aid joint working, the majority of SOA WG content is hosted in the HSSP wiki.
