Midgard is an open source persistent storage framework. It provides an object-oriented and replicated environment for building data-intensive applications.{{Cite journal|last=Jepson|first=Brian|title=Data-Drive Sites with Midgard|journal=Web Techniques|date=April 2000}}
Midgard also ships with MidCOM content management system (CMS) built on the Midgard framework.{{citation|title=Content Management Problems and Open Source Solutions|publisher=Optaros|last=Gottlieb|first=Seth|date=2006-01-23}}{{cite web |url=http://www.midgard-project.org/documentation/midcom/|title=MidCOM |access-date=2009-05-14|publisher=The Midgard Project}} MidCOM's features include web-based authoring WYSIWYG interfaces and a component interface for installing additional web functionalities,{{cite web|url=http://www.midgard-project.org/documentation/midcom-components/|title=MidCOM components|access-date=2009-05-14|publisher=The Midgard Project|url-status=dead|archive-url=https://web.archive.org/web/20090510025717/http://www.midgard-project.org/documentation/midcom-components/|archive-date=2009-05-10}} including wikis{{cite web|url=http://www.wikimatrix.org/show/Midgard-Wiki|publisher=Wiki Matrix|access-date=2009-10-26|title=Midgard Wiki}} and blogs.{{cite news|url=http://ranchero.com/2004/09/23/using_weblog_editors_with_midgard_cms|title=Using Weblog Editors with Midgard CMS|last=Simmons|first=Brent|date=2004-09-23}}
Midgard is built on the GNOME stack of libraries like GLib and libgda, and has language bindings for C, Python, Objective-C and PHP.{{cite news|last=Bergius|first=Henri|url=http://bergie.iki.fi/blog/midgard_2-more_than_just_php-more_than_just_cms/|title=Midgard 2: more than just PHP, more than just CMS|access-date=2009-05-14|date=2008-06-02}}{{cite news|last=Kostrzewa|first=Michael|url=http://www.mdk.org.pl/2009/3/26/midgard-objc-bindings|title=Midgard ObjectiveC bindings|date=2009-03-26|access-date=2009-10-26}} Communications between applications written in the different languages happen over D-Bus.{{cite news|last=Bergius|first=Henri|url=http://bergie.iki.fi/blog/interprocess_communications_in_midgard-d-bus_comes_to_the_web/|title=Interprocess communications in Midgard: D-Bus comes to the Web|date=2008-04-08|access-date=2009-10-26}} The CMS functionalities run on the LAMP (Linux, Apache, MySQL and PHP) platform.{{cite web|url=http://www.cmswatch.com/Feature/48-Midgard-1.4|publisher=CMS Watch|title=Midgard Lights An Open-Source LAMP|access-date=2009-05-14|date=2001-10-10|first1=James|last1=Christense|first2=Martin|last2=Gottlie}} Midgard can also be used with PHPCR, the PHP implementation of the Java Content Repository standard.{{cite web|url=https://phpcr.github.com/|title=PHPCR|access-date=2012-02-13}}{{cite news|title=Midgard2 PHPCR provider hits 1.0|first=Henri|last=Bergius|url=http://bergie.iki.fi/blog/midgard2_phpcr_provider_hits_1-0/|date=2011-12-23}} In early 2000s (decade) there was also a pure-PHP implementation of the Midgard API called Midgard Lite that has since been re-implemented as the midgard-portable project.{{cite web|url=https://github.com/flack/midgard-portable|title=The midgard-portable project|website=GitHub }}{{cite web|url=http://openpsa2.org/news/the-big-one/|title=The Big One}}
The project follows the synchronized, 6 month release cycle that is implemented by several major open source projects like Ubuntu and GNOME.{{cite news|url=http://thecoccinella.org/synchronized-greg|title=Synchronized Releases and Greg Kroah-Hartman|publisher=Coccinella|date=2008-11-03|access-date=2009-10-26|url-status=dead|archive-url=https://web.archive.org/web/20091215130350/http://thecoccinella.org/synchronized-greg|archive-date=2009-12-15}}{{cite news|last=Bergius|first=Henri|url=http://bergie.iki.fi/blog/midgard_and_synchronized_releases/|title=Midgard and synchronized releases|access-date=2009-05-14|date=2008-07-31}} Because of this, the version numbering reflects the year and month of a release. The version 8.09 Ragnaroek has been designated as a "Long Term Support" release.{{cite press release|last=Bergius|first=Henri|url=http://bergie.iki.fi/blog/long-term_support_for_midgard-ragnaroek_is_here/|title=Ragnaroek LTS|access-date=2009-05-14|date=2008-10-13}}
Especially the templating and page composition features of Midgard have received praise, earning honorary mentions in several CMS Watch surveys.{{cite web|url=http://www.cmswatch.com/Feature/83-Supergroup|publisher=CMS Watch|title=The Ideal CMS -- 2002|access-date=2009-10-26|date=2002-12-31|last=Byrne|first=Tony}}{{cite web|url=http://www.cmswatch.com/Feature/96-2nd-Annual-Supergroup|publisher=CMS Watch|title=The Ideal CMS -- Circa 2004|access-date=2009-10-26|date=2003-12-12|last=Byrne|first=Tony}}{{cite web|url=http://www.cmswatch.com/Feature/131-CMS-Marketplace|publisher=CMS Watch|title=Vendor Kudos and Shortcomings, Circa 2005|date=2005-09-08|access-date=2009-10-26|last=Byrne|first=Tony}}{{cite web|url=http://www.cmswatch.com/Feature/164-WCM-Marketplace|title=WCM Marketplace Web CMS Kudos and Shortcomings, Circa 2007|access-date=2009-10-26|date=2007-06-11|publisher=CMS Watch|last=Byrne|first=Tony|url-status=dead|archive-url=https://web.archive.org/web/20090925045720/http://www.cmswatch.com/Feature/164-WCM-Marketplace|archive-date=2009-09-25}} It also got score of 42 out of 45 in the Celebrity CMS Deathmatch of 2009{{cite web|url=http://jonontech.com/2009/03/25/celebrity-cms-deathmatch-part-3/|access-date=2009-10-26|date=2009-03-25|title=Celebrity CMS Deathmatch – The Aftermath|last=Marks|first=Jon}}
Etymology
The name Midgard comes from Nordic mythology, meaning Middle earth, the world of humans. Most of the Midgard developer community comes from the Baltic region,{{cite news|publisher=CMS Watch|url=http://www.cmswatch.com/Trends/708-Midgard-keeps-chugging-along|title=Midgard keeps chugging along|date=2006-06-21|access-date=2009-10-26|last=Byrne|first=Tony}}{{cite web|url=http://www.midgard-project.org/midcom-permalink-5733d7628684303c3bd2a401a6f100d5|title=Midgard: Developer locations|access-date=2009-04-25|url-status=dead|archive-url=https://web.archive.org/web/20081122023741/http://www.midgard-project.org/midcom-permalink-5733d7628684303c3bd2a401a6f100d5|archive-date=2008-11-22}} and the project has been referred by CMS Watch as the Hanseatic League of Content Management.{{cite web|url=http://www.cmswatch.com/Feature/119-CMS-Marketplace|publisher=CMS Watch|title=Web Content Management Marketplace Circa 2005|access-date=2009-05-14|last=Byrne|first=Tony}}
History
Midgard Project was started in early 1998 by Jukka Zitting and Henri Bergius for a Finnish historical reenactment organization —Harmaasudet— as a system for them to publish their material online.{{cite news|last=Zitting|first=Jukka|url=http://jukkaz.wordpress.com/2009/05/10/midgard-where-it-all-began/|title=Midgard: Where it all began |access-date=2009-05-14}}{{cite news|url=http://nettiapina.fi/blog/2008/10/29/greywolvesorg-goes-back-to-roots/|last=Hyppänen|first=Heikki|title=Greywolves.org goes back to roots|date=2008-10-29|access-date=2009-10-26|archive-url=https://web.archive.org/web/20081031094853/http://nettiapina.fi/blog/2008/10/29/greywolvesorg-goes-back-to-roots/|archive-date=2008-10-31|url-status=dead}}
Since the organization didn't have resources to maintain a large development project by itself, the open source model was chosen for creating a community of contributors to the system.{{cite news|url=http://www.devshed.com/Server_Side/PHP/Midgard/ |publisher=DevShed|title=DevShed Interviews the Developers of Project Midgard|date=1999-09-30|access-date=2009-10-26 |archive-url = https://web.archive.org/web/20010215010336/http://www.devshed.com/Server_Side/PHP/Midgard/ |archive-date = 2001-02-15}} The version 1.0 of Midgard was released to the public on May 8, 1999.{{cite press release|publisher=Linux Today|url=http://www.linuxtoday.com/developer/1999050701705NWSW|title=Midgard 1.0.0 released|access-date=2009-05-14|date=1999-05-08}} It attracted a steady stream of users, and the development project flourished despite quite primitive early user interfaces.{{cite web|publisher=IBM|url=http://www.ibm.com/developerworks/library/w-midgard/|title=DeveloperWorks: Getting to know Midgard|access-date=2009-10-26|date=2001-01-29|last=Seager|first=David|url-status=dead|archive-url=https://web.archive.org/web/20080625075616/http://www.ibm.com/developerworks/library/w-midgard/|archive-date=2008-06-25}}{{cite news|url=http://news.zdnet.com/2100-10532_22-297797.html|title=Open-source CMS: On the rise|last=McGrath|first=John|publisher=ZDnet|access-date=2009-10-26|date=2002-11-15|url-status=dead|archive-url=https://web.archive.org/web/20090719101213/http://news.zdnet.com/2100-10532_22-297797.html|archive-date=2009-07-19}}
Commercial services for the platform started to appear in early 2000. One of the first adopters was Envida, a Dutch company that realized the potential of Midgard for Web hosting purposes. First proprietary application for the platform was Hong Kong Linux Center (HKLC) Nadmin Studio content management system.{{cite web|url=http://www.3rd-evolution.de/docs/misc/midgard/|title=3rd Evolution: Midgard und Mandrake|date=2002-08-26|access-date=2009-10-26}}{{cite press release|last=Bergius|first=Henri|publisher=Linux Weekly News|url=https://lwn.net/2001/0809/a/midgard.php3|title=The State of Midgard - August 2001|access-date=2009-05-14|date=2001-08-07}}
In early 2000s (decade), Midgard developers participated actively in OSCOM,{{cite news|url=http://www.zope-europe.org/events/0303/oscomsprintzurich|publisher=Zea Partners|title=Trip Report, OSCOM Sprint Zurich|access-date=2009-10-26|date=2003-03-01|last=Everitt|first=Paul}} the collaborative organization for open source content management systems.
