Petia Wohed on YAWL at BPMinna

On Monday 30th of June, we were lucky enough to have a presentation by Petia Wohed of the Information Systems Laboratory of the University of Stockholm (and Royal Institute of Technology).

Petia contacted me last year while she was reviewing OpenWFE[ja] (and other open source workflow systems) in the light of the workflow patterns. I already blogged about the result of this work (see links at the bottom of this post).

Petia is a member of the YAWL project (workflow language and open source project) developed by the research groups of Prof. Wil van der Aalst and Prof. Arthur ter Hofstede. She delivered an excellent talk about this research effort and especially about the advantages of systems based on [Colored] Petri Nets (think Verification).

Before Petia’s presentation and my talk about OpenWFEru ruote, we had a demonstration by Zaky-san of iKnow! a social networking site for learning languages. It’s extremely successful in Japan (where it started) and it’s now expanding to the rest of the world.

Here is Petia’s presentation, it was graciously translated by Wakizaka-san to japanese :

What interested me the most was the worklet and the declarative workflow concepts. I will read carefully the papers they published about those.

Next was my talk about OpenWFEru, the slides are skinny, I rushed through them and then I demoed ruote-web, ruote-rest and the new fluo (process editing / rendering) :

Here are a few links :

(I’m certainly missing some blog reports, sorry)

Many thanks to Wakizaka-san and id:GoTheDistance for organizing those excellent BPMinna meetings (and many thanks as well to Sawada-san for inviting me to those meetings).
