	<p>
		EMF-IncQuery is a framework for defining&nbsp;<em>declarative&nbsp;</em>graph
		queries over&nbsp;<a href="http://www.eclipse.org/emf/">EMF</a>&nbsp;models,
		and executing them efficiently&nbsp;<em>without manual coding</em> in
		an imperative programming language such as Java.
	</p>

	<p>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.
