]> 2004-01-31T00:00:00-05:00 We have designed and implemented a system, dubbed PerCollab, that integrates workflow and collaboration technologies. It allows people to participate in business processes from anywhere using a traditional collaboration mechanism. It proactively engages users in business processes by pushing interaction to a convenient device of the users. PerCollab uses an extended BPEL to formally define business processes with human partners and exploits dynamic user context to solve the personal mobility problem. Our prototype implementation integrates a variety of collaboration tools: instant messaging, email and e-meeting.]]> 1867 kk2Q4eJJrMoJ 41 176290
