Abstract
This paper presents a domain model for cooperative work, taking medical examination work as an example. Cooperative work is a complex process, which involves various kinds of persons or organizations. We analyzed the domain with reference to the TDM (Triadic Domain Model). TDM specifies a domain with domain problem model, domain product model, and domain process model. The domain problem model is identified by three kinds of elements collaborator, its work items, and shared data. We set the domain product model as a combination of two representations SFC (Sequential Function Chart) and ERD (Entity Relationship Diagram), which best describes the domain. The domain process model is a process for inducing those charts from the domain problem model. A navigator prototype is developed to implement the domain process model, which enables effective domain analysis and modeling practices and prompts reuse of the domain models to neighboring domains.
