It should be emphasized that although the Semantic Infrastructure 2.0 and caGrid 2.0 roadmaps are being developed by separate project teams, it is the overarching goal and commitment of CBIIT that the two efforts ultimately be deeply integrated and merged into a single caBIG® version 2.0 semantically-aware Services-Oriented Architecture and run-time platform, that is, caGrid 2.0.
...
With respect to the overarching technology strategies being adopted to guide the development Semantic Infrastructure 2.0, there are several "givens:"
Support for legacy semantics as currently represented in caDSR via ISO 11179
...
: It is critical that the semantics currently represented in caDSR and EVS be supported in the V2 SI. However, it is equally important that both current and future caBIG stakeholders understand that as users of the V2 SI, the underlying <<representation>> of legacy semantics may – and in fact will – be markedly different in the V2 SI compared to the legacy SI. One of the primary responsibilities of the V2 SI Roadmap is to specifically identify <<and describe prototypes for>> strategies and tools which will be required to both migrate existing semantic content into the V2 SI as well as support external semantic infrastructures which may be based on representational approaches that differ from those being adopted by the V2 SI.
Semantically-Aware Service-Oriented Architecture (sSOA)

The Semantic Infrastructure 2.0 is in large part the operational support for the metadata defined the CBIIT implementation guide for the HL7 Services-Aware Interoperability Framework (SAIF). Readers interested in the specifics of the metadata defined by the CBIIT SAIF implementation guide should consult that document directly http://nci.xxx.xxx
. In particular, the chapter on the Enterprise Conformance and Compliance Framework (ECCF) provides focal point for the definition and representation of the collective set of informational and behavioral metadata which the Semantic Infrastructure 2.0 will support at both design- and run-time (via the caGrid 2.0 platform.)
