Goals and Objectives for the Semantic Infrastructure 2.0 Roadmap
The purpose of this document is to define the basic requirements for the next generation – that is, Version 2.0 – of caBIG®-CBIIT Semantic Infrastructure.
...
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.
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 Semantic Infrastructure 2.0. However, it is equally important that both current and future caBIG® stakeholders understand as users of the Semantic Infrastructure 2.0, that the underlying representation of legacy semantics will be markedly different in the Semantic Infrastructure 2.0 compared to the legacy semantic infrastructure. One of the primary responsibilities of the Semantic Infrastructure 2.0 Roadmap is to specifically identify and describe prototypes for strategies and tools which will be required to:
- Migrate existing semantic content into the Semantic Infrastructure 2.0
- Support external semantic infrastructures which may be based on representational approaches that differ from those being adopted by the Semantic Infrastructure 2.0
Reference Frameworks
Refer to Reference Frameworks for Development of caGrid 2.0 and Semantic Infrastructure 2.0 for an overview of the "givens" that apply to the technology strategies that CBIIT is adopting: Semantically-Award Service-Oriented Architecture (sSOA) and Services-Aware Interoperability Framework.
Relationship of the Semantic Infrastructure 2.0 to caGrid 2.0
The project to define the Roadmap for version 2 of the caBIG® semantic infrastructure, that is, the "next generation" of the current caDSR and EVS semantic infrastructure is being conducted in parallel with and is fundamentally coordinated with the caGrid 2.0 Roadmap project. The ultimate goal of the two efforts is to produce two complementary but integrated Roadmaps that will enable caGrid 2.0 to provide expanded semantic processing capabilities (when required) including but not limited to run-time service discovery and resolution of semantic queries. Details of both the Semantic Infrastructure 2.0 Roadmap and the caGrid 2.0 Roadmap, will be publicly available and open for community input.
Expectations and Guidelines for Review and Feedback
This is a working draft and is expected to evolve with each release.
