The CTRR Domain Analysis Model is a UML representation of the information and behavior requirements for the Clinical Trial Registration process. The DAM is rendered as a PDF document containing a behavioral model (Use Case, Activity, and Sequence diagrams); Structural Model (Class and Object diagrams); and a mapping from the DAM to sources of Clinical Trial Registration requirements (WHO.CTR, EudraCT, and CT.Gov). The CTRR Domain analysis model is a subset of the BRIDG domain analysis model containing the classes, attributes, and relationships of interest to CTRR.
