What's new! (May 15, 2008)

• Business Process Metamodel and Notation 2 (HTML: zipped, or browse)
             based on BPDM Common Infrastructure (HTML: zipped or browse)
      Submitted to the OMG, with XSD and XMI files.

  The first business modeling notation that integrates choreography and orchestration, and is interchanged with a PSL-compatible metamodel, see BPDM below (BPDM Process Definition is contained in the BPMN 2 submission, except a Design Rationale section in BPMN 2 replaces the Executive Overview in BPDM, the notation is normative, and a Diagram Interchange model is given aligned with Common Infrastructure).

  • Business Process Definition Metamodel: Process Definition (HTML: zipped or browse)
                                                                 based on BPDM Common Infrastructure (HTML: zipped or browse)
        Adopted by the OMG with XSD and XMI.

    The first PSL-compatible metamodel.

• Rule-enabled Process Modeling

  Conrad Bock

  Introduces the basic concepts and benefits of BPDM.

• Orchestration and Choreography for Business Change

  A introductory presentation of PSL.

• PSL and Flow Models (Audio, presented to Ontolog, 1:27 hr, 30.7 mb)
  Conrad Bock

  A presentation comparing the way processes are described in PSL versus flow models, the most common technique in industry.

• Constraint-enabled Process Modeling
  By Conrad Bock

  Shows how to integrate PSL into conventional process modeling.

• PSL: A semantic domain for flow models
  By Conrad Bock and Michael Gruninger

  Shows how to disambiguate common flow modeling constructs by expressing their semantics as constraints on runtime execution.

• Interprocess Communication in the Process Specification Language
  By Conrad Bock

  Extends PSL for interprocess communication. Replaces earlier papers on inputs and outputs and messaging.

• Common Logic
  International Standards Organization

  The language PSL is expressed in.

• PSL web site
  National Institute of Standards and Technology

  Gives the complete PSL ontology, applications, and references.

• OMG Systems Modeling Language (OMG SysML)
  An extension to UML for systems engineering, for requirements-based design of hardware, software, and human systems. It is a response to an RFP developed by OMG and INCOSE.

• OMG SysML site.

• SysML and UML 2.0 Support for Activity Modeling
  By Conrad Bock
  Describes the SysML extension to UML 2 Activity modeling, within a spectrum of activity modeling techniques. It updates information from a previous article.

• Systems engineering in the product lifecycle
  By Conrad Bock
  Introduces basic elements of systems engineering useful in managing the product lifecycle, as expressed in an extension to UML.

• UML without Pictures
  By Conrad Bock
  
  Reviews the primary concepts of repository-centered development with the UML, explaining the relation between notation, semantics, and model compilation.

• Eclipse repository
  Open source implementation of the complete UML 2 metamodel.

• UML 2 Activity Modeling for Domain Experts (UML as a Knowledge Language)

  Presentation reviewing UML from domain experts' viewpoint, and activity modeling in particular.

• UML 2 Composition Model

  Reviews a major upgrade to the UML composition model, which supports connections between parts at the same level of decomposition, which increases independence of reused applications and provides better plug-compatibility for components. Based partly on earlier work on composition.

• UML 2.0 Activities and Actions
  By Conrad Bock
  A series of articles covering the standard models, their semantics, with examples and repository models. Also see introductory presentation.
  • Overview
  • Actions
  • Control Nodes
  • Object Nodes
  • Partitions
  • Structured Activities

• UML 2.1.1 Specification
  Object Management Group

  Includes a major revision of UML activity modeling that gives it a flow modeling semantics, and integrates activity and action modeling, see chapters 12 and 11.

• Martin Fowler's UML Bliki

• UML 2.0 Response to Request for Information
  by Conrad Bock
  Requested Enhancements to UML structural and behavioral modeling for UML 2.

A major revision of UML action modeling covering the coded parts of a system, enabling UML to completely describe an executable system and support retargetable compilation (Model-driven Architecture).

• Goal-driven Modeling, Part II
  by Conrad Bock
  Elaborates on goal-driven modeling with extensions to object-oriented languages that directly support goal-driven modeling.

• Goal-driven Modeling
  by Conrad Bock
  The parts of a behavior interface are reviewed, and a goal-based technique for defining them is presented. Focusing on goals coordinates the choices involved in designing behavior interfaces, links them more closely to the object model, and places object-orientation within a spectrum of modeling styles that includes event-driven and rule-based approaches.

• A More Object-oriented State Machine
  by Conrad Bock
  Identifies two common approaches to state modeling and explains why they provide more powerful analysis when combined under an object-oriented framework. The technique, an elaboration of Gamma's State Pattern, is proposed as an extension to UML.

• Unified Behavior Models
  by Conrad Bock
  Examines language unification in general and of the three models above in particular, taking Unified Modeling Language (UML) as a case study.

• Three Kinds of Behavior Model
  by Conrad Bock
  Reviews three conventional forms of behavior model and how they can be used in an object-oriented way.

• Part IV: Aggregation
  by Conrad Bock and James Odell
  Proposes a model of aggregation that supports relations as parts and relations as aggregates.

• Part III: Roles
  by Conrad Bock and James Odell
  Formalizes the notion of role by extending standard object-oriented concepts.

• Part II: Mappings
  by Conrad Bock and James Odell
  Shows how standard design of relations is incomplete, and gives a better model.

• Part I: Relations as Object Types
  by Conrad Bock and James Odell
  Shows how standard analysis of relations is ambiguous when it comes time to implement, and gives a more complete model.

• UML 2 Composition Model

• Html Demo of Inheriting Part-Whole Information
  Tired of modelling part-whole without any connections between the parts? This demo is still in OOIE notation but applies with UML also.

• A User-Level Model of Composition
  by Conrad Bock and James Odell
  More about part-whole modelling from the user's perspective.

• A Foundation for Composition
  by Conrad Bock and James Odell
  Part-whole modelling from a formal viewpoint.

• Six Kinds of Composition
  by James Odell
  A taxonomy of part-whole modelling based on research in cognitive science.

An annotated description of a pre-UML metamodel (much better than UML!). It is Object-Oriented Information Engineering in terms of a small subset of itself, with clickable graphics.

• Jim Odell's web site, also covers analysis and design topics.

• UML Extensions for Agents
  by James Odell and Conrad Bock
