1 Business Informatics Group Institute of Software Technology and Interactive Systems Vienna University of Technology Favoritenstraße 9-11/188-3, 1040 Vienna, Austria phone: +43 (1) (secretary), fax: +43 (1) Q4: Standard Development Approaches UN/CEFACT Standard Development Advisory Team Conference Call, 20th January 2010 Christian Huemer & Philipp Liegl

2 ebXML is gone … but which ideas are still valid? … where enterprises of any size, anywhere can:  find each other electronically  conduct business through the exchange of XML based messages  according to standard business processes  using standard message structures  with clear business semantics  according to agreed trading partner agreements  using off the shelf purchased business applications commercial off-the-shelf software (COTS)

7 Process oriented approach 7  Which process are we talking about?  A process to be followed in the standardization  No, this is referred to as a method(ology)  The processes triggered in a company when a document arrives  No, orchestrations are not subject to standardization  The interactions between business partners  Yes, we do care about choreographies

Standard Processes? Customization of Standard Processes Reference Processes?

9 The original UMM idea – realistic? 9  Subject of standardization is an inter-organizational business process, it is defined by a business collaboration protocol  A business collaboration protocol consists of many business transactions. A business transaction exchanges one or two business documents.  A business transaction and its document exchanges are not developed in isolation, but always in the context of the business collaboration protocol  It follows, that there may be different documents of the same type when used in different business collaboration protocols

10 The CEFACT delivers only a process methodology approach 10  CEFACT defines business documents only  However, CEFACT suggests the UMM to specify a choreography of document exchanges  The definition of these choreographies is up to  Industry consortia (?)  Supply chain leaders (?)  Software vendors (?)  Individual companies – market leaders (?)  … or whoever wants to do the job ;-)  Question: Should the choreographies be contained in the registry at the 2 nd and 3 rd level?

11 Conservative: The CEFACT delivers business transactions 11  CEFACT still concentrates on business documents  Each business document results in a one way business transaction  Alternative: some business documents are grouped into two way business transactions (e.g. request for quote and quote)  CEFACT suggests UMM to specify a choreography amongst business transactions  The definition of these choreographies is still up to  Industry consortia (?)  Supply chain leaders (?)  Software vendors (?)  Individual companies – market leaders (?)  … or whoever wants to do the job ;-)  Question remains : Should the choreographies be contained in the registry at the 2 nd and 3 rd level?

12 Advanced: The CEFACT delivers reference models 12  CEFACT still concentrates on business documents  Each business document results in a one way business transaction  Alternative: some business documents are grouped into two way business transactions (e.g. request for quote and quote)  Additionally, CEFACT delivers reference models proposing a business collaboration protocol - i.e. a choreography amongst the business transactions  The customization of these choreographies is still up to  Industry consortia (?)  Supply chain leaders (?)  Software vendors (?)  Individual companies – market leaders (?)  … or whoever wants to do the job ;-)  Question remains : Should the choreographies be contained in the registry at the 2 nd and 3 rd level?

13 Visionary: The Business Entity State Centric Approach 13  A business collaboration is about changing states of one or more business entities  An exchange is about synchronizing the states of one (or more) business entities  The exchange is limited to the information required to change the state of a business entity (or all business entities that are changed)  A business entity is a data model comprising several classes (CCs / BIEs)  A data model for a business collaboration is the union of the data models of the considered business entities  An exchange specifies a view into the data model of the business collaboration. This view comprises all the data necessary to perform a state change.
