The requirements for semantic infrastructure are defined as they relate to the architecture, use cases, and stakeholders. This section presents functional requirements with tracing up to the use cases and down to the service capabilities specified later in this document. This section is not an exhaustive list of requirements and is expected to evolve as additional requirements are analyzed and defined. In addition, Semantic Infrastructure 2.0 will fully support existing caDSR users, including supporting forms created in caDSR.
This section provides a description of the following requirement categories:
The requirements address one or more use cases in each domain, as described in section 4 - Semantic Infrastructure 2.0 Use Cases. In addition to the domain-specific use-cases, the requirements also address CBIIT internal development and architecture requirements.
Specifically, CBIIT has standardized on Service-Oriented Architecture (SOA) as the foundational principle for applications architecture and interoperability. CBIIT has also adopted a formal approach, the Enterprise Conformance and Compliance Framework (ECCF), for defining service specifications. These service specifications (as defined in the NCI CBIIT SAIF Implementation Guide address both the requirements for supporting semantic interoperability, and the need to publish formal specifications that can be adopted by external organizations and vendors.
