Refer to the following sections of 6 - Dependencies Between Semantic Infrastructure 2.0 and caGrid in the caGrid 2.0 Roadmap Documents

...

In an effort similar to developing this roadmap for Semantic Infrastructure 2,0, a team is developing a roadmap for the future platform, security and tools, a team is defining the future direction for CBIIT Semantic Infrastructure. The Semantic Infrastructure Roadmap effort is expected to be deeply harmonious with the future direction of caGrid. caGrid 2.0. The Semantic Infrastructure 2.0 will be tightly integrated with the runtime caGrid 2.0. The purpose is to achieve a more comprehensive approach to computable semantic interoperability then is possible with the existing integration between caDSR and caGrid 1.x. With the adoption of SAIF (Service-Aware Interoperability Framework) and Enterprise Conformance and Compliance Framework (ECCF) and the introduction of behavioral semantics, the infrastructure of the grid must provide increasingly sophisticated support to leverage and enforce these behavioral specifications.

...

For example, the assumption of adherence to a centrally curated authoritative source of information models and terminology is no longer true; the infrastructure must gracefully accommodate local terminologies or localizations as well as standard terminologies. It must enable a path towards "as much interoperability as is possible" between any two parties, rather than enforcing full "compatibility" of all participants. Additionally, the Semantic Infrastructure 2.0 is charged with making the wealth of knowledge contained within the numerous SAIF artifacts available and consumable (in a programmatic fashion) to all the grid participants. Having runtime support for leveraging this information to inform and drive service interactions is a key value proposition for the future platform and semantic infrastructure.

...

The Semantic Infrastructure 2.0 effort is still deciding on the format and structure to be used. This decision will be important to caGrid 2.0, as it will inform how things like the publishing of service metadata work, and how higher layer semantics (for example, operation preconditions) are built upon static descriptions (for example, WSDL). It is expected, however, that a transition from ISO 11179 metadata to RIM-derived semantics is important in the future infrastructure. As further information is available from both roadmap efforts, this section will evolve to discuss the impact on the platform.
