Context-awareness refers to the idea that portable§devices can keep track of their context, of the§user's surroundings, in order to supply the user with§relevant services. The Event-Control-Action (ECA)§architectural pattern can be used to give structure§to context-aware applications by specifying a way for§them to process their data and act upon it by means§of simple if-then-constructs. These constructs, or§rules, can be specified using the ECA Domainspecific§Language (ECA-DL). Currently, there exists no§interpreter for this language. The Java Expert System§Shell (Jess) is a rule engine for Java. A rule engine§is a program that tries to match rules against§information and then triggers one or more actions.§This rule engine supports the Jess language. This§book presents how the Model-Driven Architecture (MDA)§approach can be used to develop a mapping between§ECA-DL and the Jess language, and how to set up an§automated transformation from ECA-DL rules to Jess§rules, using this mapping. This automated§transformation enables context-aware applications to§use ECA-DL rules in an already existing interpreter,§i.e., the Jess engine.
