Semantic Interoperability Framework (SIF)

SIF is composed of several Open Source components including Model Driven Health Tools (MDHT), Model Driven Message Interoperability (MDMI) and a runtime named the Information Exchange Hub (IExHub). The design environment uses MDHT which imports CDA and FHIR Templates and MDMI which manages a Referent Index containing meta data associated with business data elements. The business data elements are mapped to the templates imported with MDHT. Source data from an EHR or HIE for example is then mapped to the Referent Index business data elements completing the design process. The map from the source data to the Referent Index is then used by the IExHub to consume and create HL7 CDA or FHIR or V2 documents, resources or segments.
