Enterprise Architect Version Control
Incompatibility with LemonTree
There is no way to utilize LemonTree with EA versioning, because as LemonTree is unable to merge EA version control information properly.
Enterprise Architect Models can be configured to use various version control systems as a central repository for storing parts of the model. This allows for collaborative editing of the model.
For more details, see the official guide from Sparx Systems: https://sparxsystems.com/enterprise_architect_user_guide/15.2/model_repositories/create_a_subversion_environmen.html
This system stores Enterprise Architect Model Packages in its own proprietary xml format - which is identical to the result of an XMI Export of the packages in question.
