activities, processes, information, resources, people, behavior, goals, and constraints of a business, government, or other enterprises.”

Enterprise Model


too complex

Enterprise Model


• possible abstraction layers are:– requirements definition

– design specification

– implementation specification

– execution and run-time models

• possible views are:– organisational view

– product view

– data view (information architecture)

– function and IT view

– process view

Enterprise Model


• many different frameworks for enterprise architecture, e.g.:– Zachman Framework (very comprehensive)– ArchiMate (simplified version of Zachman)– ARIS (promoted by IDS Scheer)– TOGAF (strong IT focus)– IAF (promoted by Cap Gemini)

• currently many discussions around process design & execution, e.g.:– BPMN (notation for (IT oriented) business processes)– EPC (notation for business processes)– Petrinets (formalism often used for workflow modelling)– UML Activity diagrams – XPDL (execution language for process definitions)– BPEL (execution language for process definitions)– XLANG (execution language promoted by Microsoft)– ...

Enterprise Model


Process Lifecycle

• enterprise model evolves lifecycle• based on general Deming cycle for continuous process

improvements• sometimes also named Shewhart cycle

1. Plan

2. Do

3. Check

4. Act


Summary

• BPM definition depends on your focus• Enterprise Model describes all relevant aspects of your enterprise• different stakeholders will have different views and information

needs• lifecycle for the different parts of the Enterprise Model• BPM is done for many different purposes, but SUPER focus on:

– business process design

– business process execution

– monitoring and analysis of execution

What is BPEL?

• BPM language/model

• Language to specify behaviour of business processes

• Executable and Abstract processes– Executable processes

– Executed within a compliant environment (portability)– Abstract processes

– Specify constraints of message exchange– Provide “views” on internal processes

• Combination of graph-based language (IBM WSFL) and calculus-based language (Microsoft XLANG)


BPEL Web Service composition

• BPEL process composes (uses) Web services


Business Processes as Web services

• BPEL Process is also a Web service– functionality in terms of WSDL port types and operations

Ontology Example


Web Services & SOA

• Web Service = program accessible over the Web

• Service-Oriented Architecture (SOA): – use Web services as basic building blocks – dynamically find & invoke those Web services

that allow to solve a particular request

• Web Service Technologies: 1. WSDL Web Service Description Language

2. SOAP XML data exchange protocol for the Web

3. UDDI registry for Web Services


The Web Service Usage Process

Repository

ConsumerWeb

WSDL

SOAP

find usable Web Service

WS usage via message exchange

points to

describes


• current technologies allow usage of Web Services• but:

– only syntactical information descriptions – syntactic support for discovery, composition and execution=> Web Service usability, usage, and integration needs to be inspected

manually – no semantically marked up content / services– no support for the Semantic Web

=> initial Web Service Technology Stack failed to realize the SOA Vision

Deficiencies of WS Technology



• automate Web Service technologies by 1. rich, formal annotation of Web Services

2. automated detection and execution of Web services

• integration with the Semantic Web – ontologies as data model – Web Services as integral part of the WWW

• inference-based techniques for automated discovery, composition, mediation, execution of Web Services

• Comprehensive Framework for SESA Semantically Enabled Service-Oriented Architecture

– top level notions = SESA core elements– conceptual model + axiomatization – ontology & rule language

• International Consortium (mostly European) – started in 2004 – 78 members from 20 organizations – W3C member submission in April 2005

Web Service Modeling Ontology (WSMO)

WSMO Framework & Working Groups

Conceptual Model & Axiomatization for SWS

Formal Language for WSMO

Ontology & Rule Language for the Semantic Web

Execution Environment for WSMO

www.wsmo.org


Objectives that a client may havewhen consulting a Web Service

Provide the formallyspecified terminologyof the information usedby all other components

Semantic description of WebServices: - Capability (functional)- Interfaces (usage)

Connectors between components withmediation facilities for handling heterogeneities

WSMO Top-level Elements

(http://www.wsmo.org)




• Ontologies are the ‘data model’ throughout WSMO – all WSMO element descriptions rely on ontologies – all data interchanged in Web Service usage are ontologies – Semantic information processing & ontology reasoning

• WSMO Ontology Language WSML– conceptual syntax for describing WSMO elements – logical language for axiomatic expressions (WSML Layering)

• WSMO Ontology Design – Modularization: import / re-using ontologies, modular approach

for ontology design – De-Coupling: heterogeneity handled by OO Mediators

WSMO Ontologies


• Non functional properties author, date, ID, etc.

• Imported Ontologies importing existing ontologies where no heterogeneities arise

• Used mediators OO Mediators (ontology import with terminology mismatch handling)

Ontology Elements:Concepts set of entities that exists in the world / domain

Attributes set of attributes that belong to a concept

Relations define interrelations between several concepts

Functions special type of relation (unary range = return value)

Instances set of instances that belong to the represented ontology

Axioms axiomatic expressions in ontology (logical statement)

Ontology Specification


The Web Service Modelling Language (WSML)

• Ontology / Rule Languages– WSML Core: efficiency and compatibility

– WSML DL: decidability, open world semantics

– WSML Rule: efficient existing rule engines

– WSML Full: unifying language, theorem proving

• Languages for dynamics – Transaction Logic over ASMs

• Mapping languages– for dynamics (process mediation)

– for data (data mediation)

• Relation example relation hasRoute(ofType routeDescription, ofType route) nonFunctionalProperties dc#description hasValue "Relation that holds between

a route description and a route" endNonFunctionalProperties

■ Axiom example axiom ValidInformationQuality definedBy forall {?x} ( ?x memberOf informationQualityType

implies ?x[value hasValue “low“] or

?x[value hasValue “high“]).

■ Instance exampleinstance myPhoneNumber memberOf phoneNumber countryCode hasValue “43“ areaCode hasValue “664“ number hasValue “49322607“

BFO Purpose

• Business Functions Ontology (BFO)– Provides domain-independent vocabulary.– Introduces a robust taxonomy of organization-related functions.

• BFO aims at the precise categorization of functions and activities taking place in an organization in order to enable and facilitate the enterprise description on the process level.

• A Business Function is any functional area of / or related to an enterprise e.g. Human Resources, Sales Management, etc.

• An Activity is unit of work identified with given business process e.g. Block Sales Order, Change Sales Order, etc.


BFO Facts & numbers

• BFO is conceptually based on the SAP Business Maps Ontology:– More than 23000 instances.

– 2807 names for functions and activities were filtered out, in the second step 1578 were chosen.

– More than 580 candidates were found irrelevant or in close synonymy to concepts already included.

• The final version of BFO consists of 32 axioms and 960 concepts divided into 14 functional areas and their peer activity sub-structures:

■ The maximum depth of the taxonomical hierarchy is 5.


BFO Structure

• BFO consists of 2 parallel structures:– Function structure - reflects main functional areas of the company.– ActivityOrStep structure – reflects activities, steps or sub-phases that are conducted within the functions.

• ActivityOrStep is connected with proper Function via isSubPhaseOf attribute.


Business Function Ontology


Business Strategy Ontology


Business Goals Ontology

• Business Goals Ontology provides a standard set of properties and relations used in modelling a hierarchy of organisational business goals and enables formal verification of goal specifications

• Business goal - state of the enterprise that an action, or a given set of actions, is intended to achieve
