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® 2.0 semantically-aware ServicesService-Oriented Architecture and run-time platform, that is, caGrid 2.0.

...

• Definition and design and run-time support for informational and behavioral metadata
• Appropriate adoption of emerging Semantic Web tools and technologies
• Support for migration of legacy semantic infrastructure data and metadata
• Integration strategies and tooling requirements to for interoperability with non-CBIIT semantic representational strategies and infrastructures

...

• Major risk factors (including but not limited to complexity, tooling, and scalability) that must be managed or mitigated to enable the Semantic Infrastructure 2.0 project to succeed
• Description of prototyping activities
• Identification of various "build vs versus buy" options for specific components of the Semantic Infrastructure 2.0.

The open and transparent framework in which the Semantic Infrastructure 2.0 project is being executed is specifically designed to encourage and integrate caBIG® community input into the project's overall content. This includes integrating caBIG® stakeholder community input into the specifics of the several bulleted items in the preceding paragraphs.

...

The Semantic Infrastructure 2.0 Roadmap is being collectively authored by a team with extensive knowledge of the legacy caBIG® semantic infrastructure and the associated lessons learned from its use, as well as the realities of "what works and what doesn't" in the technology world as it moves to "Web 2.0" and "the semantic web." As described in the published process framework for the development of the Semantic Infrastructure 2.0 Roadmap, the goal of the project is to combine the perspectives and inputs of the Semantic Infrastructure 2.0 team of experts with caBIG® community input to provide the content for a roadmap that will guide the development of the next generation of caBIG® semantic infrastructure. </CNM: taken directly from caGRID RM document.

Reference Frameworks for Development of Semantic Infrastructure 2.0

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 SISemantic Infrastructure 2.0. However, it is equally important that both current and future caBIG caBIG® stakeholders understand that as users of the V2 SISemantic Infrastructure 2.0, the underlying <<representation>> representation of legacy semantics may – and in fact will – be markedly different in the V2 SI Semantic Infrastructure 2.0 compared to the legacy SIsemantic infrastructure. One of the primary responsibilities of the V2 SI Semantic Infrastructure 2.0 Roadmap is to specifically identify <<and and describe prototypes for>> for strategies and tools which will be required to both migrate existing semantic content into the V2 SI Semantic Infrastructure 2.0 as well as support external semantic infrastructures which may be based on representational approaches that differ from those being adopted by the V2 SISemantic Infrastructure 2.0.
