Chapter 2 DOI: 10.4018/978-1-7998-4891-2.ch002 ABSTRACT Process fexibility has been investigated for intra-organizational processes, but it is still an open issue for collaborative processes (CP), each of which is defned as a set of intra-organizational processes that interact together. In the literature, the version-based approach is largely used in the feld of business process management (BPM) to cope with process fexibility. However, BPM practitioners can face dif- fculties in a multi-version environment. So, the following questions arise: How can we use the version- based approach to easily model fexible CP? Does an appropriate version exist for a given situation or is it necessary to create a new one? The chapter answers these questions recommending a solution for the modeling of CP versions and the retrieval of the adequate CP version for a given situation. This solution comprises (1) a meta-model to consider the modeling of the CP versions, (2) an ontology-based approach to model and query the context of use of CP versions, and (3) a framework to provide support for both the modeling of CP versions and the context querying.
