During my visit we worked on summarising the results from our work on patterns-based evaluation of open source systems and presenting them in a paper, which we submitted to the CAiSE 2008 conference.
I also used the opportunity to meet Sybrand Jongejans from COSA. COSA GmbH is a companly initiated in 1979 in Germeny and now well established in the Netherlands. Their product, COSA-BPM is a workflow management system, which I am interested in to investigate for teaching purposes. Sybrand Jongejans provided me kindly with a free licence of the product.
