1 m3po: An Ontology for Internal and External Business Processes Armin Haller P: E: Process modelling to describe dynamic behaviour of businesses Workflow Management Systems are used for process modelling Organisations expose business functionality as Web Services and provide choreography interface descriptions to define conversational patterns in which a Web service can be consumed Lack in current choreography frameworks (BPEL, WS-CDL) is disconnection between external choreography interfaces and internal workflow descriptions Figure 2 describes our approach to connect internal Workflow Models and choreography descriptions. We developed an intermediate unifying workflow ontology (m3po) that can represent arbitrary workflows, thus reducing the number of required mappings to 2n. Methodology to generate choreography interface descriptions: INTRODUCTION APPROACH m3po is unique in the combination of workflow primitives and support for choreography-specific concepts. The ontology can act as a connecting ontology to integrate different workflow models (horizontal integration) and allows extraction of external process models (vertical integration). constructed based on an analysis of existing models written in the web ontology language WSML, making the semantics of the process concepts formal and explicit Full ontology including axiomatisation of its semantics can be found at ONTOLOGY WHAT ARE CHOREOGRAPHY INTERFACES? Choreography Interface (also called public processes, abstract processes, or provider behaviour) describe how to interact with a Web Service to consume its functionality External Visible Behavior Only describes those aspects of an internal workflow model where interaction with the web service is required Behavioural ordering of message sends and receives Armin Haller, Eyal Oren, Paavo Kotinurmi Disconnection between choreography interfaces and workflow definitions leads to two major problems: choreography interfaces have to be manually designed and synchronised with internal workflow descriptions and consistency with regard to the internal process can not be verified Abstract BPEL Interface WS-CDL Interface... multi meta-model process ontology (m3po) IBM MQ Workflow YAWL Workflow...
