Automated Transformations from ECA Rules to Jess. Edition No. 1
VDM Publishing House, Nov 2008, Pages: 96
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.
