The Semantic Integration Workbench (SIW) is a caCORE tool that assists users in adding consistent metadata to a UML model, or verifying consistency, by tagging their domain model with matching concepts from the NCI Thesaurus. This process helps bring the UML model semantically in-line with other registered caCORE-like systems, allowing for easier data-sharing between distributed systems.

The SIW was created to aid developers by providing user interfaces to perform this task and the opportunity to identify and fix any UML Loader or code generation incompatibility issues before executing these components of the caCORE SDK.

The UML Loader takes the annotated XMI file output from the Semantic Integration Workbench and loads the system's metadata into the caDSR. The UML Loader is not distributed; CBIIT loads annotated XMI files for users who have created systems via the caCORE SDK.

Information about UML Modeling is available on the CORE wiki.
