The implementations are all done using Mokum, which is an object-oriented system, in which the objects resemble employees who communicate with each other, store things in data bases, make decisions about insuranse claims, etc. Mokum is implemented in Prolog. Extensions to this Mokum system will be discussed where the Internet functions as communication medium. This tutorial consists of two parts. In the first part, a general introduction is given into cross-organizational workflow management, in the second part a more detailed treatment of the CrossFlow approach is given.
Main issues are distribution, heterogeneity, and autonomy.
The second part of the tutorial shows how the CrossFlow approach combines electronic commerce and workflow management - as such it is an instance of one of the classes introduced in the first part. The treatment covers the general CrossFlow paradigm based on dynamic service outsourcing, the CrossFlow architecture and the use of electronic XML-based contracts for service specification.
