Research on cooperative template design

A design method based on a template uses decomposition, combination, replacement and merging of the template for agility and variation of a model in global and local design. The authors have researched the fields of mechanical CAD and engineering CAD systems. Based on these works a concept of a cooperative template is presented in order to control and manage design tasks on the Net. It can inherit components that have been designed and give a nimble response for new projects if template technology is introduced into the public area of cooperative design. The paper discusses the work process of the template, its elements based on a cooperative mechanism and combines lock and semaphore functions and expands TDL (Template Design Language) using a cooperating primitive. Users are allowed to compete for design elements in the framework of visualization. Some technical problems concerning XML and JSP+Java Servlet are also discussed
