27. State Machines • Describes the Business Service Interface of a participating partner • Unambiguous definition on how to react on • Incoming messages • Messeages expected, but not received • Resulting State Machines: • The state machine of the initiator • The state machine of the responder

38. Motivation • Problem domain • Business documents exchanged in a business process in a service oriented context • UN/CEFACT provides a generic solution • Core Components Technical Specification (CCTS) • Almost no tool support possible – CCTS are standardizes as spread sheets • UML Profile for Core Components • Seamless integration into UML modeling tools possible • Seamless integration into e.g. process modeling specific models possible

39. Harmonizing the exchanged data • Known standardization efforts • UN/EDIFACT • XML based solutions (RosettaNet) • Known issues of these efforts • Multitude of different and competing standards • Inclusion of every possible element that may be required – strong overhead • Changes in the transfer syntax would require a complete reegineering • Solution • Platform independent resuable building blocks for creating shared libraries of business documents developed by UN/CEFACT

40. Core Components • Are the central building blocks of the Core Component Technical Specification • Platform independent • Used to create shared libraries of interoperable business documents • The ontological base of the CCTS is the United Nations Trade Data Element Dictionary (UN/TDED) • Initially started as part of ebXML standards suite • Now a dedicated project independent of ebXML

41. Core Component (CC) example • No business context • Independent of industry or domain ACC Aggregate Core Component BCC Basic Core Component ASCC Association Core Component

42. Business Information Entity (BIE) example • Core Components in a specific business context (e.g. travel industry) • BIEs have a specific business semantic • Qualifiers (US_) help to define and differentiate a BIE from ist associated CC and other BIEs ABIE Aggregate Busines Information Entity BBIE Basic Business Information Entity ASBIE Association Business Information Entity

43. By introducing the business context core components become business information entities Core Components (CC) Business Information Entities (BIE) BIEs are derived from CCs by restriction

44. Dependency between Core Components and Business Information Entites

45. Data Types • Qualified Data Types (QDT) are derived from Core Data Types (CDT) by restriction • Business Information Entities use QDT and CDT • Core Components use only CDT

46. The core component meta model

47. A UML Profile for Core Components • Flaws of the Core Components Technical Specification • Standardization process of Core Components is based on spread sheets • No direct integration into modeling tools possible • UML Profile for Core Components • Independent project based on the CCTS • Set of stereotypes, tagged values and OCL constraints • Can be integrated into a modeling tool of choice • Proof of concept based on UML modeling tool Enterprise Architect • UML class diagrams are used for the modeling of Core Components
