The Eclipse Data Tools Platform provides extensible frameworks and exemplary tools, enabling a diverse set of plug-in offerings specific to particular data-centric technologies and supported by the DTP ecosystem.
The Enablement project is intended to provide specialized support built on Data Tools Platform (DTP) core extension points and API. Enablement members can use the full range of these or any subset they see fit to provide specialized support for their particular data source. In general the PMC expects to see contributions to Enablement that demonstrate good usage of core DTP frameworks and tools, and not those of greater scope than could be reasonably allowed by a simple specialization delivery.
The JDT project provides the tool plug-ins that implement a Java IDE supporting the development of any Java application, including Eclipse plug-ins. It adds a Java project nature and Java perspective to the Eclipse Workbench as well as a number of views, editors, wizards, builders, and code merging and refactoring tools. The JDT project allows Eclipse to be a development environment for itself.
