In the development process of a B2B system, it is crucial that the business experts are able to express
and evaluate agreements and commitments between the partners, and that the software engineers
get all necessary information to bind the private process interfaces to the public ones. UN/CEFACT´s
modeling methodology (UMM) is a Unified Modeling Language (UML) profile for developing B2B
processes. The formalisms introduced by UMM´s stereotypes facilitate the communication with the
software engineers. However, business experts-who usually have a very limited understanding of
UML-prefer expressing their thoughts and evaluating the results by plain text descriptions. In this
paper,we describe an approach that presents an equivalent of theUMMstereotypes and tagged values
in text-based templates called worksheets. This strong alignment allows an integration into a UMM
modeling tool and ensures consistency. We show how a specially designed XML-based worksheet
definition language allows customization to special needs of certain business domains. Furthermore,
we demonstrate how information kept in worksheets may be used for the semi-automatic generation
of pattern-based UMM artifacts which are later transformed to web service definition language and
business process execution language code.
