An ECA Rule-based Task Programming Language for Ubiquitous Environments

摘要

Development of ubiquitous applications makes big difference from usual programming in that the application involves the context data management, event-handling process, and communications over distributed modules. This article introduces 'PLUE (a Programming Language for Ubiquitous Environment)' a Java based language which aims at support of rapid ubiquitous application development. UDM (Universal Data Model), the underlying context data model of PLUE, manages the heterogeneous data seamlessly. PLUE is now working on top of CAMUS (Context-Aware Middleware for Ubiquitous Robot System), although it depends little on the underlying systems.
