Hi All, Sorry for the delay, but the mailing lists are ready for MetaModel:
priv...@metamodel.incubator.apache.org d...@metamodel.incubator.apache.org comm...@metamodel.incubator.apache.org Please subscribe to them by sending email to private-subscribe@, dev-subscribe@, and commits-subscribe@ The private@ list is moderated and only MetaModel's PPMC can subscribe to them. Thanks and looking forward seeing you guys in the dev@ lists =) - Henry On Wed, Jun 12, 2013 at 6:34 PM, Henry Saputra <henry.sapu...@gmail.com>wrote: > Hi All, > > Thank you for everyone for participating and warm welcome for the > MetaModel project proposal. > > The VOTE is now officially closed with the result (* means IPMC): > > +1s: > Henry Saputra* > Matt Franklin* > Chris Mattmann* > Noah Slater* > Rahul Sharma > Ankit Kumar > Christian Grobmeier* > Arvind Prabhakar* > Kasper Sorensen > Noah Slater* > Manuel Van den Berg > Joe Brockmeier* > Suresh Marru* > Ted Dunning* > Rich Bowen > Alan Cabrera* > Marcel Offermans* > Alex Karasulu* > > 0s: > None > > -1s: > None > > > This means with 18 +1s (13 binding) and no 0 and -1 the proposal is > accepted. > > I will continue with the bootstrap process to bring MetaModel into Apache > incubator. > > Thank you again for those participated in the VOTE. > > > Thanks, > > Henry > > On Thu, Jun 6, 2013 at 3:30 PM, Henry Saputra <henry.sapu...@gmail.com>wrote: > >> Hi All, >> >> I'd like to call a VOTE for acceptance of MetaModel into the Apache >> incubator. >> The vote will close on June 12, 2013 at 6:00 PM (PST). >> >> [] +1 Accept MetaModel into the Apache incubator >> [] +0 Don't care. >> [] -1 Don't accept MetaModel into the incubator because... >> >> Full proposal is pasted at the bottom on this email, and the >> corresponding wiki is: >> http://wiki.apache.org/incubator/MetaModelProposal. >> >> Only VOTEs from Incubator PMC members are binding, but all are welcome to >> express their thoughts. >> >> Thanks, >> >> Henry Saputra >> Champion for Apache MetaModel >> >> >> P.S.
