Project Goals

The goal of the BRIDG Project is to produce a shared view of the dynamic and static semantics of a common domain-of-interest, specifically the domain of protocol-driven research and its associated regulatory artifacts.

Computable semantic interoperability (CSI) is the ability for information systems to exchange at a machine-to-machine level the meaning (rather than simply the structure) of data and/or to effectively combine functionality across machine/system boundaries. A shared semantic view is essential, but, not sufficient, to achieving CSI. A shared semantic view is essential if the clinical research community, both for itself and also as part of the larger Healthcare and life sciences communities, is to achieve computable semantic interoperability (CSI).  In order to realize the various data interchange and application interactions that are known by members of the BRIDG stakeholder organizations to be requirements for CSI, a shared view of dynamic and static semantics must be established. Please note that a shared semantic view is only one of the steps to achieving CSI.

This shared view can be used to:

  • document information requirements before designing and building a solution.
  • build the information structures in the solution.
  • trace requirements throughout the solution development process.

Through the efforts of the BRIDG Project, this shared view is expressed as a collection of visual diagrams which are, in turn, expressed using the iconography and grammar of the Unified Modeling Language (UML) and the HL7 Reference Information Model (RIM). This set of visual diagrams plus the underlying inter-diagram relationships, definitions, explanations, and examples (instance diagrams which illustrate the semantics of the diagrams in more detail) are collectively referred to as the BRIDG Model. For a short introduction to UML, please see the BRIDG User Guide that is published with each release of the model.
