The rapidly growing networks that connect more and more computers offe
r new levels of communication. This is also valid for the area of work
flow management. The VORTEL project defines a teleservice for the inte
roperability of workflow management systems. This teleservice integrat
es heterogeneous workflow management systems of different vendors and
allows distributed workflow management. The teleservice consists of a
set of protocols for the communication of different classes of workflo
w management system components. This paper introduces the generic VORT
EL architecture and describes one of the defined protocols in detail.
Furthermore, a vision of the use of a workflow teleservice as a public
service is given.
