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 ŒMetaModel¹ 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 ³dragged² 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), it¹s 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 Œvasc¹ 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.
