An Enhanced Visual Workbench for

OGSA-DAI

Rob Baxter

OGSA-DAI is…

• a powerful, robust, stable open-source platform enabling

Internet-scale data integration for e-Research!

• an “important [e-Research] software toolkit” (Atkins 2010)

OGSA-DAI has…

• a powerful execution engine for data workflows

• a “kit of parts” of some 120+ server-side data access,

processing and transformation components

• a client toolkit offering a straightforward Java API to

application developers

• a world-wide user base and active open-source community

• Hmm, OK, I’m convinced… how do I use it?

Using OGSA-DAI?

• Did we mention the client toolkit offering a straightforward

Java API?

• A Java API…? OK… And…?

• Well, how about a new data-intensive workflow language

called DISPEL?

• Hmm, that sounds potentially interesting, but…

what I really want is a visual programming tool, an IDE

The ADMIRE Workbench!

Excellent! Can I have it now?

• The ADMIRE Workbench is a public beta

• It needs a usability overhaul, some TLC, better docs

• That’s what this project is all about!

• “An Enhanced Visual Workbench for OGSA-DAI”– Starting August 2011– Until mid-Dec 2011– Providing a learnability ramp for data-intensive e-Research
