Abstract

To realize and integrate various kinds of media information with the least data, a new hierarchical software architecture has been developed. Aiming at easier manipulation, this system is based on a model driven method. Four kinds of generic models; data, object, role, and process models are employed in this system. These models have hierarchical interfaces from data to process layers. In case of the data model, attribute values of data are defined in template forms. If necessary, several constraints are attached to them. In the object model case, every object is defined by `formal' and `feature' structures. Formal structures are defined by our object network which is composed of noun and verb objects. Feature structures are mainly composed of a set of properties, which are described by constraints. For the role model, schemes of various levels of coordination relating multiple roles are represented to satisfy their intentions. These structures are defined by generic goals and constraints. The process model is designed so that all roles are executed concurrently in order to satisfy their interactive intentions under cooperative or competitive conditions. Integrated results of various media can be provided by using or Extensible WELL (Window-based Elaboration Language) system.
