OW2 is an independent non-profit international consortium dedicated to developing open-source software code infrastructure for middleware information systems. OW2 federates IT vendors and users, universities, and research centers from Europe, Asia, and the Americas, representing IT professionals.
OW2 was founded in 2007 as an independent organization to foster the ObjectWeb code base of open source middleware. ObjectWeb was a joint project launched in 2002 by INRIA, Bull, and France Telecom; in 2005 INRIA signed an agreement with OrientWare, a joint project between Peking University, Beijing University of Aeronautics and Astronautics (now Beihang University), National University of Defense Technology, CVIC Software Engineering Co., Ltd, and the Institute of Software at the Chinese Academy of Sciences. All became founding members of OW2 along with Engineering, Red Hat, and Thales Group.
OW2 hosts circa 100 open-source projects. [1] Projects make up the OW2 code base and are foundation of all OW2 activities. Projects can be submitted into the OW2 code base after meeting some minimum requirements and applying. At this point, a Project is considered to be in "Incubation," the first of OW2's defined lifecycle stages. Upon gaining code contributors, growing, and meeting rigorous requirements, a project can apply for "mature" status. The application is then reviewed by the OW2 Technology Council and granted mature status or kept in incubation. If a project stops evolving and updating, it can then be moved to the third lifecycle stage, "Archive," where it is no longer active but can use OW2's infrastructure services.
In 2008, only a year after its founding, OW2 began hosting its projects via Concurrent Versions System (CVS) and Apache Subversion (SVN) using GForge. [2] Later, support for CVS was disabled and hosting via Git using Gitorious began. [3] In 2018, only a decade after it had begun using it, OW2 decommissioned its use of GForge and SVN in lieu of Git, after having migrated to using GitLab. [4] [2]
OW2con is an annual conference for the OW2 community, organized since 2009.
Apache Subversion is a software versioning and revision control system distributed as open source under the Apache License. Software developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation. Its goal is to be a mostly compatible successor to the widely used Concurrent Versions System (CVS).
GNU Savannah is a project of the Free Software Foundation initiated by Loïc Dachary, which serves as a collaborative software development management system for free Software projects. Savannah currently offers CVS, GNU arch, Subversion, Git, Mercurial, Bazaar, mailing list, web hosting, file hosting, and bug tracking services. Savannah initially ran on the same SourceForge software that at the time was used to run the SourceForge portal.
The National Institute for Research in Digital Science and Technology (Inria) is a French national research institution focusing on computer science and applied mathematics. It was created under the name French Institute for Research in Computer Science and Automation (IRIA) in 1967 at Rocquencourt near Paris, part of Plan Calcul. Its first site was the historical premises of SHAPE, which is still used as Inria's main headquarters. In 1980, IRIA became INRIA. Since 2011, it has been styled Inria.
Gna! was a centralized location where software developers could develop, distribute and maintain free software. The service was shut down in 2017 after 13 years in service for dozens of software projects and millions of downloads served.
TortoiseCVS is a CVS client for Microsoft Windows released under the GNU General Public License. Unlike most CVS tools, it includes itself in Windows' shell by adding entries in the contextual menu of the file explorer, therefore it does not run in its own window. Moreover, it adds icons onto files and directories controlled by CVS, giving additional information to the user without having to run a full-scale stand-alone application.
Mantis Bug Tracker is a free and open source, web-based bug tracking system. The most common use of MantisBT is to track software defects. However, MantisBT is often configured by users to serve as a more generic issue tracking system and project management tool.
ViewVC is an open-source tool for viewing the contents of CVS and SVN repositories using a web browser. It allows looking at specific revisions of files as well as side-by-side diffs of different revisions. It is written in Python and the view parameters can be modified directly in a URL using a REST style interface.
GForge is a commercial service originally based on the Alexandria software behind SourceForge, a web-based project management and collaboration system which was licensed under the GPL. Open source versions of the GForge code were released from 2002 to 2009, at which point the company behind GForge focused on their proprietary service offering which provides project hosting, version control, code reviews, ticketing, release management, continuous integration and messaging. The FusionForge project emerged in 2009 to pull together open-source development efforts from the variety of software forks which had sprung up.
Open-source software development (OSSD) is the process by which open-source software, or similar software whose source code is publicly available, is developed by an open-source software project. These are software products available with its source code under an open-source license to study, change, and improve its design. Examples of some popular open-source software products are Mozilla Firefox, Google Chromium, Android, LibreOffice and the VLC media player.
A source-code-hosting facility is a file archive and web hosting facility for source code of software, documentation, web pages, and other works, accessible either publicly or privately. They are often used by open-source software projects and other multi-developer projects to maintain revision and version history, or version control. Many repositories provide a bug tracking system, and offer release management, mailing lists, and wiki-based project documentation. Software authors generally retain their copyright when software is posted to a code hosting facilities.
Advanced Resource Connector (ARC) is a grid computing middleware introduced by NorduGrid. It provides a common interface for submission of computational tasks to different distributed computing systems and thus can enable grid infrastructures of varying size and complexity. The set of services and utilities providing the interface is known as ARC Computing Element (ARC-CE). ARC-CE functionality includes data staging and caching, developed in order to support data-intensive distributed computing. ARC is an open source software distributed under the Apache License 2.0.
In software development, version control is a class of systems responsible for managing changes to computer programs or other collections of information such that revisions have a logical and consistent organization. The following tables include general and technical information on notable version control and software configuration management (SCM) software. For SCM software not suitable for source code, see Comparison of open-source configuration management software.
In FOSS development communities, a forge is a web-based collaborative software platform for both developing and sharing computer applications.
Bountysource is a crowdsourcing website for open source bounties and since 2012 also for crowdfunding. Users can pledge money for tasks using micropayment services that open source software developers can pick up and solve to earn the money. It also allows large-scale fundraising for big improvements on the project. It integrates with GitHub using its bug tracker to check if the problem is resolved and connect the resolution with GitHub's pull request system to identify the patch. When the users agree that they are satisfied and the project maintainer merged the proposed changes to the source-code, Bountysource will transfer the money acting as a trustee during the whole process.
Acceleo is an open-source code generator from the Eclipse Foundation that allows people to use a model-driven approach to building applications. It is an implementation of the "MOFM2T" standard, from the Object Management Group (OMG), for performing model-to-text transformation.
CloudStack is open-source Infrastructure-as-a-Service cloud computing software for creating, managing, and deploying infrastructure cloud services. It uses existing hypervisor platforms for virtualization, such as KVM, VMware vSphere, including ESXi and vCenter, XenServer/XCP and XCP-ng. In addition to its own API, CloudStack also supports the Amazon Web Services (AWS) API and the Open Cloud Computing Interface from the Open Grid Forum.
Software Heritage provides a service for archiving and referencing historical and contemporary software — with a focus on human readable source code. The site was unveiled in 2016 by Inria and is supported by UNESCO. The project itself is structured as a non‑profit multi‑stakeholder initiative.
