....in software development. Provence [74] is a PCDE using Marvel as one of its components. It focuses on creating an open PCDE architecture allowing the incremental integration of external software tools. A short description of the main components of Provence is given at the end of this section. Oz [21, 22] is another system extending Marvel and focusing on the decentralization aspects of process centered environments. The issues researched in Oz are beyond the scope of this paper and are not described here. Marvel has a layered client server based architecture. Many development environments may be ....

.... work includes process modeling and execution support for synchronous collaborative work where multiple users perform an activity together at the same time, and delegating an activity, a task or a tool session to an individual or a set of users for immediate or potentially delayed execution [6, 23]. For example, the multi flag field, originally introduced for MTP, is now used within SEL to identify cases where the delegation primitive in the process step should be interpreted to fork the envelope multiple times on behalf of each of multiple designated users [3] We are also working on ....

....the activity with the user whose on behalf the Summit rule was invoked, or to a delegated user if it was specified in the rule. In case of a multi user groupware activity (e.g. virtual whiteboard) Oz provides mechanisms to define the participants and bind the activity to them at run time, see [10]. 3.3.4 Post Summit The first step in Post Summit asserts the appropriate (local and remote) effects of the Summit rule, depending on the output from the activity. Since the executed rule is identical at all participating sites (because of the common sub process invariant) this phase can be ....
....The Treaty abstraction appears to support particularly well interoperability modeling of process and data. Two areas that still need improvements are in modeling interoperability at the user and the tool levels, which are related to groupware technology. Preliminary work has been done in [10]. Work in Emerald City revealed another area that requires improvements in Oz, namely better support for multi site operations between trusted sites, particularly for interoperability modeling. The Treaty operation as a single command (with the issuer being administrator in both sites) was a step ....

....goal driven or event driven chain which is useful for simulation or training purposes. Built in operations such as add an object, delete an object, etc. are modeled as rules for a uniform approach. Oz provides means for modeling and enacting synchronous and asynchronous groupware tools [19, 5], which were not supported by Marvel, but the details aren t relevant to this paper. Marvel and Oz support nearly the same object oriented data definition and query languages. A class specifies primitive attributes (integers, strings, timestamps, etc. file attributes (pathnames to files in an ....
