Welcome to CHORCH

CHORCH denotes the Choreography-To-Orchestration framework that will provide tools and methods for analyzing and performing ebXML BPSS ( ebBP) choreographies.

ebBP is a dedicated B2Bi choreography standard that allows for declarative and technology-independent definition of so-called BusinessTransactions and BusinessCollaborations.
BusinessTransactions are used for specifying the exchange of up to two business documents as well as state alignment features and Quality-of-Service requirements. BusinessTransactions can be considered to be atomic building blocks for changing the state of integration partners in a consistent way. BusinessCollaborations are then built by choreographing these atomic building blocks.

ebBP is not directly executable and abstracts from implementation details. It is a valuable tool for achieving agreement between integration partners about the “what” of B2Bi processes whereas the “how” is left unspecified.

Web services and WS-BPEL are a potential implementation technology for ebBP choreographies. A main research direction of CHORCH therefore is execution of ebBP using Web services and BPEL technology (cf. publications).
