We describe two models for federating process-centered environments (PCEs): homogeneous federation among distinct instances of the same environment framework enacting the same or different process models, and heterogeneous federation among diverse process enactment systems. We identify the requirements and consider possible architectures for each model, although we concentrate primarily on the homogeneous case. The bulk of the paper presents our choice of architecture, and corresponding infrastructure, for homogeneous federation among Marvel environment instances as realized in the Oz system. We briefly consider how a single Marvel environment, or an Oz federation of Marvel environments, might be integrated into a heterogeneous federation based on ProcessWall's facilities for interoperating PCEs.

Architectures for Federation of Process-Centered Environments
, 1996
"... 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 ident ..."

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.

. Decentralized process#centered software engineering environ# ments #PSEEs# provide an architecture for interoperabilitybetween mul# tiple PSEEs with heterogeneous processes. Atomicity is a standard cor# rectness model for guaranteeing that a set of activities occurs as an atomic unit# or none of them occur at all. Within a single PSEE# atomic# ity is the concern of its database system. In a decentralized environment# however# the autonomous environments must #nd ways to cooperate if an atomic unit is split between multiple PSEEs. This paper describes a #exible atomicity model that enables process administrators to reconcile the con#ict between local autonomy and global atomicity and cooper# atively specify the scope of multi#site atomicity based upon the desired semantics of multi#site tasks in the decentralized PSEE.
