RE: [PROPOSAL] MetaModel for the Apache Incubator
Okay, got it! We looked at it and it looks fine. We would need to make explicit in exhibit A that it's excluding xBaseJ code, since that will be removed from the project when it moves to Apache. Other than that we're happy to sign the SGA.

Re: [PROPOSAL] MetaModel for the Apache Incubator
Henry, Thank you for submitting this proposal. I am very glad to be a mentor for this project and look forward to working with you and the broader community. I have a couple of comments with regards to the stated proposal - First - as noted in the proposal MetaModel has been an open source project with contributions coming from various corners of the world. Given this development model, do the individual contributors hold copyright over their contributed code? If so, you will likely need their consent in order to provide this code to the Incubator for the purposes of starting this project. Second - I noticed that the proposal calls out the LGPL dependency that will be removed before sourcing the initial drop. Along the same lines, I urge you to go through the the legal FAQ [1] to make sure that there are no other dependencies that merit removal or special handling.

Re: [PROPOSAL] MetaModel for the Apache Incubator
Hi Arvind, For concern 1 I will let the lead engineer Kasper to answer. I believe if the contributors already signed copyright agreement to Human Inference then it should be fine since it means all code contributions belong to Human Inference which will then be transferred to ASF. Someone might want to help clarifying this if I am mistaken. As for concern 2, I have scanned the master pom.xml's dependencyManagement section and looks like all dependencies are Apache 2.0 friendly. Again, Kasper could help verify if this is the case. - Henry On Wed, May 29, 2013 at 10:31 PM, Arvind Prabhakar arv...@apache.orgwrote: Henry, Thank you for submitting this proposal.

If Kasper stops to commit, the project is dead. Two contributors are listed as have an interest to commit if accepted to the ASF. Why didn't they contribute before? It reads a bit like they want to have an @apache.org e-mail address than a real interest in the project. Hopefully other IPMC'lers find some time to comment here too.

Anyone else interested, now that the project page has been updated with the full contributor list ? -Original Message- From: Kasper Sørensen [mailto:kasper.soren...@humaninference.com] Sent: 22. februar 2013 09:39 To: general@incubator.apache.org Subject: [PROPOSAL] MetaModel join the Apache Incubator Hi all, On behalf of Human Inference, I'm proposing the MetaModel project to join the Apache Incubator: http://wiki.apache.org/incubator/MetaModelProposal Sorry about re-iterating this project proposal.

I'm the main developer, but not the only one. Additional contributions are from Human Inference and Xebia employees primarily, and a few individuals.

RE: [PROPOSAL] MetaModel join the Apache Incubator
Yea, sorry bout that, was postponed too late I think. I've updated the contributor list now, grouped them in three groups: 1) Initial committers (as per the proposal guide), 2) Contributors with known interest if project is accepted in Incubator and 3) Previous contributors (that aren't too likely to contribute in a incubation phase). http://wiki.apache.org/incubator/MetaModelProposal -Original Message- From: Olivier Lamy [mailto:ol...@apache.org] Sent: 22. februar 2013 14:23 To: general@incubator.apache.org Subject: Re: [PROPOSAL] MetaModel join the Apache Incubator 2013/2/22 Kasper Sørensen kasper.soren...@humaninference.com: I'm the main developer, but not the only one.
