Dear all,
in order to avoid a potential trademark issue between the EMF-IncQuery project and IncQuery Labs Ltd. (a key supporter of both EMF-IncQuery and VIATRA), we would like to propose to change the name of the EMF-IncQuery project, after consultation with the Eclipse Foundation.
Considering the close relation of the EMF-IncQuery and VIATRA projects (both in terms of common committers and technological dependencies), we are proposing to combine the renaming with a restructuring that involves merging EMF-IncQuery into VIATRA and introducing a new component structure.
To this end, we would like to establish a new structure that suits our development style better, and in general makes everyone's lives easier. We have already talked about this on the last meeting [1], and the proposed new joint project structure is available in a mindmap [2].
Merging the EMF-IncQuery project into VIATRA will also make release engineering easier, as we will be able to build the required components together and create shared repositories for end-users to obtain everything needed.
For version numbers, we plan to use two schemas: one for mature components, and one for incubation components. We suggest version numbers 1.2.0 and 0.12 as that is higher than any version we used in releases before. This will require VIATRA as a project to graduate from an incubation project (but it can still have incubating components after graduation).
On the management side, we propose that everybody that is committer of either EMF-IncQuery or VIATRA should become a committer for the new, merged project.
To give you a complete picture, we foresee that the only major drawback of this combined proposal will be that we will break the API compatibility for the existing users of EMF-IncQuery. For this reason, we plan to provide a migration assistant feature that can be used by our users to upgrade their existing projects automatically, similarly to what we have already built for previous versions [3].
In terms of timing, we would like to do this restructuring early next year, to have the first release available at the end of February or the start of March.
In summary, we would like to ask all committers two questions:
• Do you agree with renaming “EMF-IncQuery” to “VIATRA Incremental Queries”?
• Do you agree with the new proposed project structure, i.e. moving the code from EMF-IncQuery to VIATRA?
Please vote with a ‘+1’ or ‘-1’ to both questions as soon as possible by replying to this email on the developer mailing lists. We kindly ask everyone who is a committer on both projects to vote on both mailing lists.
If you need any clarification regarding the plan detailed above, please do not hesitate to ask.
Best regards,
Ábel, István and Zoltán
