OGSA-DAI source code on SourceForge

OMII-UK's OGSA-DAI project is currently in the process of transforming itself from being an open source product to an open source project, encouraging an open development model so that the OGSA-DAI community can become more involved in future development of OGSA-DAI. As part of this process we are migrating our source code to reside in an open source project site hosted by SourceForge.

The initial upload of our new Subversion repository can now be browsed online at:

http://ogsa-dai.svn.sourceforge.net/viewvc/ogsa-dai/

or can be anonymously checked out using an SVN client:

http://sourceforge.net/scm/?type=svn&group_id=261620

Please see our SourceForge SVN pages for full information on how to check out the code using an SVN client, the repository structure, how to build it and how to run unit and system tests within your own environment:

http://sourceforge.net/apps/trac/ogsa-dai/wiki/OGSADAISubversion./a>

If you would like to get involved please see our governanace model at:

http://sourceforge.net/apps/trac/ogsa-dai/wiki/GovernanceModel

Over the next month we will be migrating additional code into this repository to bring it into alignment with our OGSA-DAI 3.2 release. This includes adding DQP which is now an integral part of the OGSA-DAI product.

Migration to SourceForge

We are starting a process of migrating OGSA-DAI infrastructure to SourceForge where an OGSA-DAI project account has been created:

We will slowly be moving infrastructure to this site and deprecating or repurposing existing infrastructure as we go along. We hope to have completed this process by October 2009. 13th May 2009

OGSA-DAI - from open source product to open source project

Since 2002, the OGSA-DAI project has been developing OGSA-DAI - its unique open source product for access to and integration of distributed heterogeneous data resources. We have now received from EPSRC funding for an additional year's work, until April 2010.

A key part of our work over the next year will be to evolve OGSA-DAI from an open source product into an open source project. This is in line with OMII-UK's goal to promote software sustainability, and will guarantee that the lifetime of the OGSA-DAI product exists outwith any single institution or funding stream.

Over the lifetime of the project, an international community of users and developers from a myriad of areas (including medical research, environmental science, geo-sciences, the arts and humanities and business) has formed around OGSA-DAI. The open source project will provide this community with a focal point for the evolution, development, use and support of both OGSA-DAI and its related components, providing a means by which members of the community can develop and release their components alongside the core product. It will also provide the community with an avenue to ensure the sustainability of their components.

Over the next few months we will set in place the governance and infrastructure of the OGSA-DAI open source project. This will be done in conjunction with key community members, and will draw upon the expertise of our OMII-UK partners in Manchester and Southampton and of the Globus Alliance. We aim to roll out our open source project site in October.

Alongside this, a number of other activities are being undertaken:

  • Work on distributed query processing will continue, looking at more powerful distributed relational queries and integrating work on relational-XML queries produced by Japan's AIST.
  • A comprehensive review of performance, scalability and robustness will be undertaken, so allowing us to identify key areas for redesign.
  • New activities for security, delivery and access to indexed and SAGA file resources will be released.
  • A new version of OGSA-DAI, with many improvements including refactored APIs and exploiting Java 1.6, will be released.
  • We will participate in inter-operability testing with the OGF DAIS working group, a vital part in the evolution of the WS-DAI specifications into standards.

This new phase of the project is accompanied by some staffing changes. Rob Baxter, head of EPCC's software development group, and manager of the ADMIRE data mining project, takes over as OGSA-DAI project manager. Mario Antonioletti moves to a new role of OGSA-DAI's outreach coordinator and open source community liaison and Mike Jackson to the role of technical lead.

The OGSA-DAI project is a collaboration between EPCC and the National e-Science Centre (NeSC). For more information contact the OGSA-DAI team at info@ogsadai.org.uk.

OGSA-DAI is a part of OMII-UK. OMII-UK is an open source organisation that empowers the UK research community by providing software for use in areas as diverse as bioinformatics, astrophysics and archaeology. All its software is free and fully supported. For more information e-mail support@omii.ac.uk or visit http://www.omii.ac.uk.

OGSA-DAI Website Availability

Due to work being done on our web server the OGSA-DAI website will not be available on the Saturday 17th and Sunday 18th of January. We apologise for any inconveniance that this might cause. 14th January 2009

OGSA-DAI WS-DAIR 1.0 released

The OGSA-DAI project team have released OGSA-DAI WS-DAIR 1.0. OGSA-DAI WS-DAIR provides an implementation of the OGF DAIS Working Group WS-DAIR specifications. It was built using OGSA-DAI 3.1 but is a stand-alone product and requires only Apache Tomcat and a relational database to be used.

For further information please see the downloads page or the documentation.
