EMF-IncQuery is a framework for defining declarative graph queries over EMF models, and executing them efficiently without manual coding in an imperative programming language such as Java.

With EMF-IncQuery, you can:

• Define model queries using a high level yet powerful query language (supported by state-of-the-art Xtext-based development tools)
• Execute the queries efficiently and incrementally, with proven scalability for complex queries over large instance models
• Integrate queries into your applications using essential feature APIs including IncQuery Viewers, Databinding, Validation and Query-based derived features with notifications.

In February 2016, the EMF-IncQuery project was merged into VIATRA. This page contains information about accessing the previous versions of EMF-IncQuery. After version 1.2, the first combined release comes out (planned for April 2016), we recommend migrating to the new version. For details about downloading these version, please look at the VIATRA download page.
