A set of functions and predicates (as defined by Google Collections / Guava libraries) along with a set of utility methods to help navigating and editing Eclipse EMF models. EMFPath depends on Google Guava. Guava is available as OSGi bundles from the guava-bundle project.

"ModelDriven.org is a community of government, commercial and university members who use, develop and integrate open source and commercial capabilities to enable agile business solutions based on model driven methods and technologies. ModelDriven.org is standards based, leveraging Model Driven Architecture® as defined by the OMG and the Semantic Web as defined by W3C. This community has both a user membership and a provider membership. The user community drives the agenda - ..Read More >>"

"An "executable" UML model is one with a behavioral specification detailed enough that it can effectively be "run" as a program. This can be extremely valuable in order to test and validate the model, independently of the one or more implementation platforms to which the system being modeled will ultimately be deployed. Or, in some cases, the model itself can actually be run as the production implementation, given an appropriate execution environment. There have been model execution tools and environments for years, even before UML. However, each tool defined its own semantics for model execution, often including a proprietary action language, and models developed in one tool could not be interchanged with or interoperate with models developed in another tool. A previous post described Stephen Mellor's quest of more than a decade to change this through OMG standards for precise UML model execution semantics and a UML action language. In 2008, this led to the adoption of the Foundational UML (fUML) specification, providing the first precise operational and base semantics for a subset of UML encompassing most object-oriented and activity modeling. The fUML specification still did not provide any new concrete surface syntax, however, tying the precise semantics solely to the existing abstract syntax model of UML. This meant that, in order to fully specify a detailed behavior in a UML model - say the effect behavior of a transition on a state machine or the method of an operation of a class - one still had to draw a very detailed, graphical activity diagram.

The Java Content Repository (JCR) standard, which is based on the Java Specification Requests JSR170 (version 1.0) and JSR 283 (version 2.0), provides a Java-centric object-oriented storage API specifically targeted at content management scenarios. The JCR is not a content management system or a full-fledged content management system API, but rather a content repository API. A content repository provides a common API for all content-driven applications and CMS components, which require access to the content. It provides methods to read, write, and query content. The primary motivation of the JCR standard is to provide a standard and vendor-neutral programmatic interface for content repositories, allowing applications of multiple vendors to interact efficiently.

"JSwat is a graphical Java debugger front-end, written to use the Java Platform Debugger Architecture and based on the NetBeans Platform. JSwat is open-source software and is freely available in both binary and source code form. Its features include sophisticated breakpoints; colorized source code display with code navigator; byte code viewer; movable display panels showing threads, call stack, visible variables, and loaded classes; command interface for more advanced features; and Java-like expression evaluation, including method invocation.

"Developing rigorous and responsive web service client applications has always been a challenge for architects and developers working with SOA. JAX-WS 2.0 comes with one effective solution to this problem: asynchronous web service invocation. In this article, we will provide an exposition of this technology with examples built upon the reference implementation. The JAX-WS programming model offers two models for invoking operations asynchronously - polling and callback. Both methods allow the client to continue processing while waiting for a response."

The database administrators are extremely methodical professionals. Though the Enterprise Manager tool automates much of the gathering of information that is needed by database administrators
