Why sBPMN?
■ BPMN is a widely used notation for BPM. ■ SUPER needs an entry point for BPMN
users.■ BPMN is a graphical notation that needs
explicit semantics (provided by sBPMN).
Lessons learnt:■ SUPER needs to create entry points. ■ SUPER needs to be independent of
specific notations.■ SUPER needs to remain up-to-date as
standards change.

Why sEPC?
■ SUPER’s proof of capability to handle multiple entry points corresponding to distinct perspectives.
■ EPC is different from BPMN.
■ The sematics for EPC is distinct from that for BPMN.

Why BPMO?
Intermediate representation for:■ Abstracting over different notations,
perspectives, levels of understanding■ Bridging different notations■ Bridging the world of modelling,
execution and analysis■ Providing a central platform for
connecting additional knowledge sources
The above facilitates inter-representational reasoning and querying.
► Eg, one can pose a query on a BPEL execution trace and the answer uses knowledge from the original BPMN diagram and the organisational context.

Why sBPEL?
■ sBPEL is SUPER’s ontology at the receiving end of ontology-based model transformation (mediated by BPMO) hooking into execution (BPEL through its BPEL4SWS extension).
■ sBPEL and BPEL4SWS have hooks allowing for the execution of SWS and of their compositions.
■ We can reason about sBPEL, that which
is about to be executed and that which comes after execution (thus supporting analysis).

Why BRO?
■ Support high level reasoning about behaviour
► E.g. compliance checking, composition validation
■ This reasoning can include any knowledge carried within the ontology stack.

Why a domain ontology stack?
■ Resources for enriching the representation of BP models based on BPMO.
■ Domain ontologies provide values for attributes of BPMO process instances.
■ Vertical domain with three levels of generality:
► Generic business domain (organisation) ontologies ► Extended by telecommunication ontologies► Extended by use case specific ontologies.

Why use case ontologies and knowledge bases?
■ Each enterprise has its specifics:► Organisational structure► Variants and additions to BP models► Data structure.
■ Each enterprise has its own data.
■ Common umbrella framework and common representation formalism.

Why NGOSS Ontologies (YATOSP)?
© SUPER 12.04.23 Pierre Grenon, OU 56
■ The Telemanagement Forum (TMF) is an association of telecommunication enterprises and IT providers.
■ The TMF’s development of the New Generation Operation Support Systems (NGOSS) results, among other things, in a set of standards.
■ These were ontologised in SUPER.
SID Shared Information Domain Common domain vocabulary
NBC NGOSS Business Contract Telco business process contract
eTOM Enhanced Telco Operation Map Telco business process functions
TAM Telco Applications Map IT systems for process execution

Why an ontology stack?
■ A stack is formed of elements which are putatively independent to some degree.
■ The degree of independence depends on application context sampling the stack (facilitating partial reuse).
■ Also in some cases, size matters and the break down of ontological resources can be motivated by efficiency and technical parameters.
■ Finally, SUPER is a collaborative project with distributed competences and responsibilities.

Why ontologies?
■ Representing reality■ Bridging between different representations, possibly
of the same things using different representation formalisms
■ Providing explicit semantics to existing representation formalisms
■ Abstracting from existing representations■ Supporting updatable and potentially growing
interoperability with centralised mapping■ Supporting scalability through mechanisation and
automatised translation ■ Supporting sharing and reuse over the Semantic Web

Why Ontology-based Representation for BPM?
■ Heterogeneous sources and viewpoints abstracted into a single ontology-based representation of processes, their structures, relations, and properties for which BPMO provides the backbone.► Translation from and/or to BPMN, sEPC, BPEL
■ Heterogeneous formalisms streamlined into a single knowledge representation formalism (WSML):► bringing BP Models to machines► facilitating integration and interoperability► allowing automatisation, execution, reuse► in an accessible and scalable manner.
