Minutes

• Backward compatibility for Xtext: current version + the last two versions.
• Changes for VIATRA 2.2.0: EPL v2.0 copyright header update.
• Expressing ordering between model objects is still a huge challenge. Gabor analyzed previously possible solutions on the topic. TODO: look up the results of this analysis. Istvan’s suggestion: a proposal should be made to support this ordering by the beginning of Summer.
• Create a catalogue of long-term enhancements outside the bug tracker.
• Graphical query editor:
  • Aggregate expression support is not complete
  • Embedded Xtext editor is not working properly
  • How pattern documentation should be created and maintained for this tool is still a question
