Architectures for Federation of Process-Centered Environments

Ben-Shaul, Israel Z.; Kaiser, Gail E.

We describe two models for federating process-centered environments, homogeneous federation where the interoperability is among distinct process models enacted by different copies of the same system and heterogeneous federation with interoperability among distinct process enactment systems. We identify the requirements and possible architectures for each model. The bulk of the paper presents the specific architecture and infrastructure for homogeneous federation we realized in the Oz system. We briefly consider how Oz might be integrated into a heterogeneous federation to serve as one of its interoperating PCEs.
