Epsilon Examples

This EOL program builds a simple Object Oriented model from scratch. It is a useful example of the basic features of EOL.

This application uses EGL to generate HTML-based documentation for Ecore metamodels.

This example shows how EOL can be run from Java code (without the Eclipse-based tools).

In this example, an Object Oriented ECore metamodel is annotated with Exeed-specific annotations so that instances of it can be visualized properly with the Exeed editor. (Updated 28 Feb 2007)

In this example, an ECL comparison is used to compare two Object Oriented models. Then its match-trace is input into an EML merging that merges the two models.

In this example, ECL and EML are used to implement the aspect oriented modelling case study presented at http://reuseware.sourceforge.net/index.php?title=Aspect_Oriented_Modeling_(example)

In this example, an ECL comparison is used to compare an Entity with a Vocabulary model. Then its match-trace is input into an EML merging that merges the two models. Coordination is achieved using the Epsilon ANT tasks. This example demonstrates that ECL and EML can be used to compare/merge heterogeneous models.

This EVL validation contains constraints and critiques that validate an Object Oriented model.

In this project an EOL program implements Dijkstra's shortest path algorithm for directed graphs. Moreover, an EVL module validates that a graph is acyclic and has only positive weight-edges as required by the algorithm.

This EOL program generates a textual representation of a graph that can be visualized using the Dot program of the Graphviz (www.graphviz.org) platform.

This ETL transformation transforms an Object Oriented model into a Relational Database model. The type mappings between the OO and the DB metamodel are provided in a separate Type Mapping model.
