" Further talk about the overall approach to REST access in the Guvnor project expanded from the JIRA issue, ad hoc discussions on the dev list to Jevis Liu's "AtomPub Interface for Guvnor" proposal on the Drools community wikI. Taking off from where Michael Neale's original "Guvnor AtomPub Interface" started in 2008 and expanding into categories, metadata and other return types, this page became a rough, but working implementation specification.

Janino is a super-small, super-fast Java™ compiler. Not only can it compile a set of source files to a set of class files like the JAVAC tool, but also can it compile a Java™ expression, block, class body or source file in memory, load the bytecode and execute it directly in the same JVM. Janino is not intended to be a development tool, but an embedded compiler for run-time compilation purposes, e.g. expression evaluators or "server pages" engines like JSP. JANINO is integrated with Apache Commons JCI ("Java Compiler Interface") and JBoss Rules / Drools. JANINO can also be used for static code analysis or code manipulation. JANINO can be configured to use the javax.tools.JavaCompiler API (available since JDK 1.6), which removes the Java 5-related limitations.

"http://www.atompub.org/ defines a simple interface over HTTP to publish and subscribe to artifacts (files) and collections of artifacts (services/packages). AtomPub interface serves following purposes: 1: provide "feeds" for people/systems to monitor for changes: For example, user subscribes to a feed which lists contents of package or user subscribes to feed which lists changed contents in a package 2. provide the default remote api to push/pull content and meta data from the repository. This allows other applications to integrate with Guvnor by accessing repository content via atom pub programmatically."
