International audienceCOOPER platform is a collaborative, open environment that leverages on the idea of flexible, user-centric process support. It allows cooperating team members to define collaborative processes and flexibly modify the process activities even during process execution. In this paper we describe how the incorporation of decentralized user data through mashups, allows the COOPER platform to support the definition and execution of the so called user profile based activities, i.e., process activities that are adapted based on the preferences of the process actors. We define two basic types of user profile based activities, namely user adapted activities and user conditional activities. The first are modeled according to the user profile data, while the second employs the same user data to enable automatic workflow decisions
