You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 52.91.0.0/16 has been blocked (disabled) by ‪JJMC89‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:26, 2 September 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''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 [[Americas|the Americas]], representing IT professionals.

== History ==

OW2 was founded in 2007 as an independent organization to foster the [[ObjectWeb ASM|ObjectWeb]] code base of [[open source]] [[middleware]]. ObjectWeb was a joint project launched in 2002 by [[INRIA]], [[Groupe Bull|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]].

==Activities==
===Projects===
OW2 hosts circa 100 open-source projects.<ref>((Cite web|url=https://projects.ow2.org/view/wiki/|title=OW2 Projects - OW2 Project Marketplace (wiki.WebHome)|website=projects.ow2.org))</ref> 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.

====Hosting====
In 2008, only a year after its founding, OW2 began hosting its projects via [[Concurrent Versions System]] (CVS) and [[Apache Subversion]] (SVN) using [[GForge]].<ref name="tc">((cite web |title=Gforge decommission |work=OW2 Technology Council |url=https://tc.ow2.org/view/wiki/Gforge_decommission |access-date=2022-05-05))</ref> Later, support for CVS was disabled and hosting via [[Git]] using [[Gitorious]] began.<ref>((cite web |title=Which version control system can I use? Do you support SVN? Do you support GIT? |department=FAQ |work=ow2.org |url=https://www.ow2.org/view/About/FAQ#FAQ.23_software_for_version_control |access-date=2022-05-05 |url-status=live |archive-url=https://web.archive.org/web/20210902182258/https://www.ow2.org/view/About/FAQ#FAQ.23_software_for_version_control |archive-date=2021-09-02))</ref> 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]].<ref>((cite web |title=GForge has been discontinued |department=IT Infrastructure |work=ow2.org |url=https://www.ow2.org/view/IT_Infrastructure/GForge_discontinued |access-date=2022-05-05))</ref><ref name="tc"/>
