In this document we tried to explain why we decided to change some aspects of Xtext’s architecture. We consider most changes as minor but when it comes to scopes you will face a conceptual enhancement that did not exist in oAW Xtext. We tried to explain why it is not easily possible to come up with an adapter for scoping.
That said you might not have the time to do the migration and wished to have advice for migrating, especially from oAW linking to TMF linking. You’re welcome to ask any questions in the newsgroup and we’ll try to help you as much as possible in order to get your projects migrated. Also, if you don’t want to do the migration yourself we (itemis AG) can do the work for you or help you with that.
