Attribute Mapping Inversion

BXAML is a bidirectional (bx) language for expressing attribute mappings of Ecore-based models in an Java-aligned syntax. It is built using the Xtext framework and extends the Xbase Expression language.

The BXAML language makes it possible to derive a backward transformation for an attribute mapping using an extensible library of operator-specific inverters.

BXAML was developed in the context of the Vitruvius Project.

Development and Usage

Prepare Development Environment

1. Download and run the Mars 1 Release of the Eclipse IDE for Java and DSL Developers
2. Install Subversive (SVN Team Provider) and a svn connector (e.g. SVN-Kit) using the Eclipse Marketplace
3. Check-out all plug-in projects of the XOCL4Inv language from the inversion branch of the Vitruvius svn repository (user: anonymous password: anonymous)
4. Run the GenerateMIR MWE2-Workflow
5. Troubleshooting
   • Open the intermediate generator model, right-click an run "Generate Model Code"
   • Do the same for the SimplestA genmodel and theSimplestB genmodel
   • Clean all workspace projects

Run the editor

1. to run the BXAML editor start a new Eclipse instance from the Eclipse in which all plug-ins where checked out as specified above (this can be obtained e.g. by creating a new run configuration with default settings).
2. create a new *.MIR-file to open the editor

Testing and Evaluation

Prepare Testing and Evaluation Environment

1. import both projects in the test plug-in into the workspace of the new runtime Eclipse

Run the JUnit Tests of the Evaluation

1. run all JUnit-Tests in the test1 folder

Jira Project

Please report bugs using the JIRA Issue Management for Vitruvius
