The OGSA-DAI team will be at OGF-25 in Catania, Sicily from 2nd-6th March (see http://www.ogf.org/OGF25). We’re involved in the following sessions.
“Distributed data access and management with OGSA-DAI” (Monday: 9-12:30)
This session is a 1.5 hour introduction to distributed data access and management with OGSA-DAI looking at data access and integration scenarios, OGSA-DAI’s workflows and how they can realise these scenarios, case-studies and the relationship between OGSA-DAI and OGF WS-DAI specifications. This is followed by a 1.5 hour session of invited talks from representatives of the
ADMIRE, AIST, BEinGRID and LaQuAT projects who will discuss how they are using OGSA-DAI in their projects. We’ll also describe the OGSA-DAI roadmap for the next year with its focus on moving OGSA-DAI from an open source product to an open source project.

OGSA-DMI WG (Wednesday: 11-12:30)
http://www.ogf.org/gf/event_schedule/index.php?id=1528
“Databases and metadata on the Grid: tools and communities” (Thursday: 9-15:30 - exact time TBC)
We have been invited to give a presentation on OGSA-DAI as a part of this session. Our presentation will focus on the evolution of OGSA-DAI. From its origins as a project to provide data access and integration capabilities to the e-Science community and, in parallel drive the development of data access specifications at GGF/OGF, through to being a de-facto data management standard in its own right. We’ll also describe our upcoming evolution from an open source product to an open source project.

DAIS-WG (Thursday: 4-5:30)
The OGSA-DAI team will be carrying out its ongoing engagement with the
DAIS-WG in the process of producing web services standards for data access.

Asides from that we’ll be with our friends from Southampton and Manchester on the OMII-UK stand (no. B08)…
Hope to see you in Sicily!
Hi folks,
We had a well attended session on “Distributed Data Access and Management using OGSA-DAI” of about 20 attendees for each half (and that doesn’t include members of our team!) and a range of questions including - OGSA-DAI’s support for unstructured files, performance compared to JDBC, ease of implementation of the SEE-GEO scenario, will WS-DAI supercede OGSA-DAI, OGSA-DAI compliance for gLite.
In the second half of the session, Carlos Buil Aranda of UPM gave an overview of the ADMIRE project’s use of OGSA-DAI and AIST’s WS-DAI RDF implementation.
Isao Kojima gave an overview of AIST’s work as a user of OGSA-DAI in the GeoGrid project and as a developer of OGSA-DAI/DQP in looking at supporting RDF resources and Sparql, distributed query processing across relational, XML and WebDB resources. This, in addition to developing WS-DAI-RDF as part of the OGF WS-DAI working group activity.
Mike Jackson of EPCC gave a presentation on behalf of EPCC’s BEinGRID project team on their work in extending OGSA-DAI to develop components for use in BEinGRID’s business experriments and, subsequently, of generall application to businesses. This included a GUI-based installation (or data publisher) tool for GOSA-DAI and an OGSA-DAI SQL trigger which allows OGSA-DAI workflows to be executed in response to changes (e.g. insertions, deletions, updates) in a database table.
Finally, Mark Hedges of Kings College London gave an overview of the LaQuAT project. This is a collaboration between the Centre for e-Research and Arts and Humanities Social Science Research Centre at KCL and EPCC and is focusing on using OGSA-DAI’s workflows, SQL views and DQP components to provide access to epigraphical databases containing meta data about classical artefacts e.g. Roman legal texts or Greek papyri.
Slides from the Monday session on using OGSA-DAI for data access and management are now online.
