The Knowledge Content Committee's purpose is to define the standard "content" (models and terminology) underpinning the standard HSPC services against which consuming third party application developers can develop their applications.
Our main effort right now is producing "HSPC standard" FHIR profiles for use by the HSPC services. For more about that effort, see the HSPC Profile Strategy page.
Please join our discussion list here: HSPC Knowledge Content Committee Forum. This will subscribe you to the modeling@healthservicesplatform.org list.
