About BRIDG Project

last modified 2012-06-28 14:32

The Biomedical Research Integrated Domain Group (BRIDG) Model is an information model, specifically an instance of a Domain Analysis Model (DAM), representing a shared view of the concepts of protocol-driven clinical research. This structured information model is being used to support development of data interchange standards and technology solutions that will enable semantic (meaning-based) interoperability within the biomedical/clinical research arena and between research and the healthcare arena.

A Domain Analysis Model (DAM) can be defined by the following characteristics:

   An implementation-independent view of a domain of interest
•   Represents a shared understanding of concepts
•   Uses domain terminology and is understandable to domain experts who may have little or no UML skills but yet, are a primary consumer
•  Includes unambiguous definitions
•  Uses complex data types designed specifically for the domain of focus, in our case healthcare
•  Follows good modeling practices
•  Enables interoperability when systems share a common understanding
•  Is built by analysts and subject matter experts who develop consensus
•  Informs development of downstream artifacts

 The BRIDG model is a conceptual model from which detailed design level artifacts can be built.  At present this domain analysis model is focused on the static or data semantics of the domain of clinical research.  Therefore, the majority of domain semantics are represented as UML Class Diagrams. The behavioral or dynamic semantics that are typically part of a DAM by definition will be added to BRIDG in future releases.
