[Henry Saputra <he...@gmail.com>]

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

> > === Background ===
> >
> > The MetaModel project was initially developed by eobject.dk to service
> > the DataCleaner application (http://datacleaner.org). The main
> > requirement was to perform data querying and modification operations on a
> > wide range of quite different datastores. Furthermore a programmatic
> query
> > model was needed in order to allow different components to influence the
> > query plan.
> >
> > In 2009, Human Inference acquired the eobjects projects including
> > MetaModel. Since then MetaModel has been put to extensive use in the
> Human
> > Inference products. The open source nature of the project was reinforced,
> > leading to a significant growth in the community.
> >
> > MetaModel has successfully been used in a number of other open source
> > projects as well as mission critical commercial software from Human
> > Inference. Currently MetaModel is hosted at
> http://metamodel.eobjects.org.
> >
> > === Rationale ===
> >
> > Different types of datastores have different characteristics, which
> always
> > lead to the interfaces for these being different from one another.
> > Standards like JDBC and the SQL language attempt to standardize data
> > access, but for some datastore types like flat files, spreadsheets, NoSQL
> > databases and more, such standards are not even implementable.
> >
> > Specialization in interfaces obviously has merit for optimized usage, but
> > for integration tools, batch applications and or generic data
> modification
> > tools, this myriad of specialized interfaces is a big pain. Furthermore,
> > being able to query every datastore with a basic set of SQL-like features
> > can be a great productivity boost for a wide range of applications.
> >
> > === Initial goals ===
> >
> > MetaModel is already a stable project, so initial goals are more oriented
> > towards an adaption to the Apache ecosystem than about functional
> changes.
> >
> > We are constantly adding more datastore types to the portfolio, but the
> > core modules have not had drastic changes for some time.
> >
> > Our focus will be on making ties with other Apache projects (such as POI,
> > Gora, HBase and CouchDB) and potentially renaming the ‘MetaModel’ project
> > to something more rememberable.
> > This includes comply with Apache Software Foundation license for third
> > party dependencies.
> >
> > == Current status ==
> >
> > === Meritocracy ===
> >
> > We intend to do everything we can to encourage a meritocracy in the
> > development of MetaModel. Currently most important development and design
> > decisions have been made at Human Inference, but with an open window for
> > anyone to participate on mailing lists and discussion forums. We believe
> > that the approach going forward should be more encouraging by sharing all
> > the design ideas and discussions in the open, not only just the topics
> that
> > have been “dragged” into the open by third parties.  We believe that
> > meritocracy will be further stimulated by granting the control of the
> > project to an independent committee.
> >
> > === Community ===
> >
> > The community around MetaModel already exists, but we believe it will
> grow
> > substantially by becoming an Apache project. With MetaModel used in a
> wide
> > range of both open and closed source application, both at Human Inference
> > (HIquality MDM), it’s open source projects DataCleaner, SassyReader and
> > AnalyzerBeans and by other parties (such as the Quipo data warehouse
> > automation project), we believe that the critical mass to sustain a
> > community is there.
> >
> > === Core developers ===
> >
> > MetaModel was founded by Kasper Sørensen in 2009. Later it was
> > incorporated as a core library by Human Inference, meaning that more than
> > 20 developers have been involved in its making in this commercial
> setting.
> > Furthermore a smaller number of contributors have submitted patches for
> the
> > library. Others have started building other interesting data-oriented
> > libraries on top of MetaModel, for instance the ‘vasc’ open source
> project
> > by Willem Cazander, which is an implementation of the Java Persistence
> API
> > (JPA) for all the datastores supported by MetaModel.
> >
> > === Alignment ===
> >
> > MetaModel already makes good usage of existing Apache projects such as
> > POI, CouchDB and OpenOffice. Furthermore developers from the Apache Gora
> > project have indicated a need for a project like MetaModel to solve
> > specific uniform datastore access needs.
> >
> > == Known risks ==
> >
> > === Orphaned products ===
> >
> > The contributors and the contributing organization (Human Inference) have
> > a very strong dependence on MetaModel already and will continue to have
> > that for a long time. The continued need for this vendor to support new
> > types of datastores and maintain existing functionality will ensure that
> > MetaModel is not in the risk of being orphaned.
> >
> > === Inexperience with Open Source ===
> >
> > MetaModel is already open source, and has been so for many years. Main
> > contributors of the project have also contributed to other open source
> > projects such as DataCleaner and Apache Mahout. The openness of Apache is
> > arguably more extensive, but we are only encouraged and delighted to be
> > handling the project in a more open manner.
> >
> > === Homogenous Developers ===
> >
> > Frequent committers are currently located in Denmark, The Netherlands and
> > India. They are used to working in a distributed environment.
> >
> > === Reliance on Salaried Developers ===
> >
> > Initial committers for MetaModel will depends on salaried based
> developers
> > to contribute to this project, but given the dependence on MetaModel from
> > both commercial and open source projects, the project would continue
> > without issue if no salaried developers contributed to the project.
> >
> > The goal is build diverse community to contribute back to MetaModel
> > project.
> >
> > === Relationship with Other Apache Products ===
> >
> > MetaModel depends on several Apache products including: commons-lang,
> > commons-io, commons-codec, http-components, POI, CouchDB, OpenOffice and
> > XMLBeans.
> >
> > Furthermore MetaModel is built by Apache Maven.
> >
> > === An Excessive Fascination with the Apache Brand ===
> >
> > The ASF has a strong brand, and that brand is in itself very attractive.
> >
> > We are interested in joining the ASF in order to increase our contacts
> and
> > visibility in the open source world.
> > Furthermore, we have been enthusiastic users of Apache Software
> Foundation
> > projects, and would feel honored by getting the opportunity to join and
> > contribute back to the community.

> > === Initial source ===
> >
> > MetaModel has been developed since 2009 and have undergone a couple of
> > major changes (indicated by the 2.x and 3.x versions).
> >
> > The code is used in mission critical systems and is considered very
> stable
> > and high performing.
> >
> > The source includes a fork of the xBaseJ project’s code, which will be
> > removed upon incubation. This code was originally GPL licensed, but
> granted
> > with a special license to MetaModel to be forked and relicensed using the
> > current LPGL license of MetaModel.
> >
> > Removal of the xBaseJ code will effectively mean that the Apache variant
> > of MetaModel will not have support for dBase database files. We imagine
> > that the dBase module could live on as a separate pluggable module under
> > the LGPL license, outside of Apache.
