Eclipse is many things in one!




It’s an open source project
It’s an open community
It’s a platform for tool integration
It’s a technology for building reusable

It’s a Java IDE
Eclipse & CoBrA

Why am I interested in Eclipse?

Need a GUI for monitoring and browsing
the internal process of the Broker





Extensible
Cross-platform (Windows, Mac, Linux)
Familiar user interface and widgets
Easy to install and patch updates
JSP/Servlets & Java Swing -- no good!
Some Eclipse Vocabularies


Eclipse Plug-in: a modular component
that contributes certain functionality to
the platform
Eclipse Plug-in Feature: a special
plug-in that a developer creates to
enable “one-click” install/update of his
own plug-in contribution

CoBrA Eclipse Viewer (CEV)



A tool for browsing the knowledge and policy
that are stored in the Context Broker and for
monitoring the reasoning process of the
Broker.
It can be used as a stand alone application
for browsing OWL ontology documents or
models.
Inspired by the Java Spider application
