What is this project about?
Some users only need to see some parts of a model, others have to get the full model extended with data from another model, and others simply access to a combination of information coming from different models. Based on the unquestionable success and usefulness of database views to solve similar problems in databases, EMF Views brings the same concept to the modeling world.
These screencasts provide a smattering of the capabilities of this project. Note that these videos have been recorded with an older version of EMFViews, but they still show the overall principles and capabilities of the approach.

What can you find in this repository?
These are the core plugins:
org.atlanmod.emfviews: This is the main component of the tool. It includes the core logic behind viewpoints and views.
org.atlanmod.emfviews.virtuallinks: An Ecore-based model of links used to construct viewpoints and views.
org.atlanmod.emfviews.virtuallinks.delegator: This package delegates the creation of virtual links to concrete implementations.
org.atlanmod.emfviews.virtuallinksepsilondelegate: This project generate virtual links from the Epsilon Comparison Language (ECL).
We have also defined two DSLs, VPDL and MEL, which have accompanying Eclipse plugins for edition:
org.atlanmod.emfviews.vpdl: ViewPoint Description Language; useful for creating a viewpoint by filtering multiple metamodels, with a syntax inspired by the
SELECTquery in SQL.
org.atlanmod.emfviews.mel: Metamodel Extension Language; can extend metamodel with new classes, attributes, relations.
examples folder contains ideas of how to use EMF Views and the DSLs:
emfviews-tutorial: Create your first Viewpoint and View.
vpdl-tutorial: Define a viewpoint with VPDL.
- Import the projects of the “plugins” folder into the workspace
- Run a “Runtime Eclipse” with the workspace to try the plugins. In the “examples” folder there are several example projects to test the project
