- A new means of assessing conformance of artifacts and applications to improve software development and semantic consistency
- A semantically linked artifact repository for easy discovery of the registry contents
- A metadata repository that links to the artifact repository
- A cross artifacts editing dashboard that allows model artifacts to be linked to other artifacts such as terminology value sets
- A rules engine for operatiing on the artifact repository and metadata repository to enable dynamic annotation and the comparison of artifacts
- A reasoning platform that executes inferencing and links to rule engines enbaling the discovery of implicit information rather than soley explicit information
- Introduction of additional semantic modeling standards (ISO 21090, HL7 RIM, Semantic Web Languages (OWL, RDF)) in order to handle the broad requirements of enabling simpler query functions and enriched data discovery
- A more automated artifact governance platform that includes the ability for community input to governace decisions
- Mutiple model transformation tools and APIs
- Tools for authoring standards compliant artifacts including schemas, models, and terminology value sets
- Tools for authoring forms using the new semantic models in order to meet the demands of customers who require these to meet meaningful use requirements and who want full semantics for data aggregation and discovery
- Broad use of Model Driven Architecture technologies
- Close integration with caGRID 2.0

The table below shows a high level view of the gaps between what the current semantic infrastructure provides and what the Semantic Infrastructure Version 2 will provide for several use case driven functionalities.
Requirement | SIV1 | SIV2 | Gap closed by SIV2 |
|---|---|---|---|
Retrieve any artifact | CDE | Domain models, Logical models, terminology, documents, forms, behavioral models an specifications | Ability to retrieve any artifact in context |
Manage artifacts | CDE Curator only | Open to all | Ability for anyone to annotate an artifact and submit to governance |
Service discovery | Constrained to service discovery on the GRID | Service discovery tied to artifacts that can link to data provision | Ability to discover a service, its links to other services, the service contract, the artifacts that are behind the service |
Bench to Bedside Form creation | Clinical research form creation | Form creation of any healthcare, clinical research, or life science form | Supports all form users and conforms to ONC requirements for meaningful use forms |
Decision support across artifacts | None | Semantic linkage across multiple artifacts, inference of implicit knowledge about the artifacts and their relations | Provides enhanced search and retrieval of artifacts and extends the metadata for any artifact through inference of relations |
Conformance Testing | None | Semantic reasoning and inference with automated classification, relations, and traceability of artifacts | Provides the full traceability and conformance testing for artifacts in a standard (ECCF) framework |
Data discovery | ? | Semantic inference, semantic to relational adaptors and scalable relation graphs relate services to artifacts, artifacts to terminology, and terminology to data | Provides the ability to link services to each other and to the explicit definitions of the data they provide |
