Introduction

The aim of BREIN is to transfer business collaboration onto the Grid

• Complex relations between different Service Providers and their Business Processes have to be analysed and mapped to the grid

• Existing business models are usually broken down to business process models which have become a commodity

• Need of flexible adaptive ICT systems which understand business processes and can respond to changing business needs

A Modelling Framework supporting these tasks is needed


The Modelling Challenge in BREIN

Modelling Framework has been defined to allow: • Process oriented Requirements Analysis• Specification of Software Architecture• Externalization of Expert Know-How

Based on the Scenarios with complex suppy Chains and inter-organisational collaboration the requirements were derived

Modelling layers:• Business Level: Supply Chains, Business Processes, and Goal Models• IT-Level: Workflow and Service Description and Software Architecture

• Best Practise Roadmap

The Modelling Challenge in BREIN

Following Modelling Challenges have been identified1. Syntactic Level: concerns models and their representation

– Models are stored in different formats– no unified way to access them

2. Semantic Level: concerns the modelling languages and the integration of them

– Integration of two modelling languages usually results in a gap– Example: “IT-Business gap”

3. Contextual Level: same term is used in different contexts– Example: Service

• Business expert: non-material equivalent of a good• Technician: software that is deployed as a web service

– Ambiguity is a mayor problem– common understanding of the domain between all stakeholders is

essential


Addressing the BREIN Modelling Challenges

1. Syntactic Level: through the use of standards– One generic model repository acting as a mediator, all models stored in

XML format– Model may be accessed through web service interfaces– Standard exchange formats such as EPC, UML/XMI, BPEL, OWL

2. Semantic Level: through Meta-model integration pattern– Modelling methods are coupled using a “transition layer” containing

concepts form both worlds– Example: “IT-Business gap”

3. Contextual Level: through integration of meta-models and ontologies

– Most difficult challenge– Bootstrapping approach: Models serve as basis for the generation of the

ontology and vice versa– Definition of a Terminology to assist the user in modelling– Two related Modelling services available: Ontology Generator,

Modelchecker


Contextual ChallengeOntology Generation (1)

Use of models use of business process models for the generation of ontologies- filtering them according to relevant concepts and transformation into an

ontologyWe distinguish two approaches:- ontology on a meta-model layer - ontology on a model layer

Contextual ChallengeModelchecker (1)

Checking the consistency of the models according to the terminology– ontology is considered complementary to models– defining the domain conceptually, contains the correct

terminology and may serve as reference during modelling

Conclusion and Outlook (1)

The BREIN Modelling Framework has been implemented trying to address the presented Modelling Challenges

The Modelling Framework is currently in use by the project consortium

Next steps include:• Development of Best Practise Roadmap• Development of additional Modelling Services• Detailed definition of „Workflow and Services

Description“ - Building Block• Reference models for all related methods
