Lodz, April 29th 2009 -- The Midgard Project has released stable release of Midgard2 9.03 "Vinland" - the new generation of the Midgard content repository.
## About this release Midgard2 9.03 is targeted at web framework and desktop application developers. It provides a comprehensive set of content repository APIs that can be used to build replicated information applications that share their information using a common storage layer and replication tools. Vinland series of Midgard2 is not intended to act as a content management system, and so no CMS tools are shipped with the release. Midgard2 Vinland however can be used to build a CMS, or to refactor existing CMS tools to work with a repository-centric model. In this release we provide Content Repository API bindings for the following programming languages: C, Python, PHP and Objective-C. D-Bus signals are used to inform different Midgard2 applications about things happening in the repository, enabling for example a PHP website and a Python background process to communicate with each other. ## Midgard2 Midgard2 is a content reporitory. It provides an object-oriented and replicated environment for building data-intensive applications. Midgard's philosophy includes building on top of a well-known and supported GNOME libraries like glib and libgda on the system end, and connecting with popular programming languages like PHP and Python. Data storage can utilize SQLite with desktop and mobile applications, or a database server like MySQL or Postgres for web application storage. The Midgard2 platform enables developers to define a storage structure once and use it on both web and desktop applications, with the possibility of easy data replication between the two.

The new Midgard2 architecture is instead built on top of libgda, the GNOME database abstraction layer. This enables Midgard to be used with various storage engines, including: * MySQL * Postgres * SQLite * Microsoft SQL Server * Oracle * DB2 ### Built-in replication and metadata All Midgard objects are automatically equipped with a consistent set of metadata properties that can be used for access control and workflow. In addition, Midgard provides an API for serializing and unserializing stored objects in XML format that can be used for replicating data between different systems. The replication architecture can be used for staging/live web environments or mobile applications that synchronize between each other or a web back-end. # Planned for next Midgard2 releases * Midgard MVC, an elegant PHP MVC framework written for Midgard2 # Midgard resources * [Download page and changelog for latest release][1] * [Bug reporting][2] ## User and developers support: * [Users' forum][3] * [Developers' forum][4] * IRC: #midgard on irc.freenode.net * [#midgard on Qaiku][6] ## About Midgard The Midgard Framework development started in 1997 and it was initially released as free software in May 1999. Midgard Project has since gathered an active user and developer community, powering thousands of web sites ranging from simple organizational intranets to large community portals. Midgard is being developed by an international team of professionals. Midgard's development team includes new media designers, system integrators and content management consultants. Midgard development has been supported by several commercial and governmental entities including the European Union and the Swedish Internet Foundation.
