    • multiple forms of linear referencing

      • ESRI route and measure technology

    • hierarchical/geographical organization of pipeline features

    • Feature behavior during centerline editing operations

    • Links to external systems – ERP, Document Management, Work Order MS

  • Abstract Classes

  • Overview of the model l.jpg
    Overview of the Model

    • APDM is the intellectual property of ESRI

      • Managed in trust by the Pipe Interest Group (Petroleum User Group)

    • Version 1.0 Build the model

      • Focus on the technology, the core and conceptual classes in the model.

  • Version 2.0 – 3.0 Link to the Enterprise

    • Refine the conceptual model, expand the core

      • Activities, External Documents, OwnerOperator, EventID

  • Version 4.0 Metadata

    • Data content

    • Schema Description and Management

    • Object behavior

    • Best Practices  Interoperability

    Apdm version 4 0 l.jpg
    APDM Version 4.0

    • Abstract Classes (Core Attributes and Relationships)

      • Centerline Objects, Facility Objects, Online/Offline Objects

      • Response to editing the centerline

      • Auditing feature/object edits

  • Core Classes

    • ControlPoint, StationSeries, AltRefMeasure, Lineloop, Subsystem, SubsystemHierarchy, LineloopHierarchy, Product, OwnerOperator, SubsystemRange, Site, Activity, ActivityHierarchy, ExternalDocument

  • Metadata Classes

    • Formal definition to describe behavior of reference modes

      • Units, Basis, Type

    • Listing and APDM categorization of classes within geodatabase

      • Each class in the APDM will inherit from one of the APDM Abstract Classes

    • Online Locations for Offline Features

      • Listing of offline/online class pairs

      • Listing of calculation methods for determining derivation of online locations

  • Inline History and Auditing

  • Facilities and Non-Geometric representation of features

  • Arcgis pipeline data model apdm8 l.jpg
    ArcGIS Pipeline Data Model (APDM)

    • APDM Logical Model Poster – shows abstract classes, metadata classes, core classes and example concrete classes

    Abstract classes10 l.jpg
    Abstract Classes

    • Object based abstract classes showing centerline objects, facility objects and non-facility objects

    Abstract classes11 l.jpg
    Abstract Classes

    • Feature based abstract classes showing centerline objects, online/offline objects, facility objects and ‘online’ location objects

    Abstract classes inheritance l.jpg
    Abstract Classes- Inheritance

    • Example showing how a ‘concrete’ class is derived via inheritance from the APDM abstract classes

    Core classes l.jpg
    Core Classes

    • Represent the core classes within the model that must be implemented

    • These classes represent critical parts of a pipeline reflecting centerline editing and integration with other enterprise systems

      • ControlPoint – known points of XY and station value location for a given reference mode

      • StationSeries – a route feature built from control point for a given reference mode

      • AltRefMeasure – stores alternate reference mode information for online features

      • Lineloop – a series of connected station series forming a ‘line’ or ‘route’

      • LineloopHierarchy – ability to categorize lineloops into logical groupings

      • Subsystem – an area or zone along the pipeline used to break it up into logical regions

      • SubsystemHierarchy – ability to categorize subsystems into logical groupings

      • SubsystemRange – the ‘online’ location of a subsystem along the centerline

      • Product – the product transported by the pipeline

      • OwnerOperator – owner and operator information for the assets of a pipeline

      • Site – any site boundary on or along the pipeline

      • Activity – things that ‘happen’ during the operation and maintenance of a pipeline

      • ActivityHierarchy – ability to categorize activities into logical groupings

      • ExternalDocument – reports, regulatory and source documents that specifiy or document assets and events on or along the pipeline

    Metadata classes l.jpg
    Metadata Classes

    • Describes the internal structure of the model for validation and verification

    Implementing apdm l.jpg
    Implementing APDM

    • APDM is built for the geodatabase

      • It is an object model

      • It describes feature editing behavior

      • It provides meta-data or meta-models that can be integrated with other data models

      • APDM Core  APDM Tables  Add/modify classes and attributes

      • APDM Core  PODS Business/Feature/Event Tables  Add/modify classes and attributes

      • APDM Core  ISAT Business/Feature/Event Tables  Add/modify classes and attributes

      • APDM Core  Any pipeline data model business tables …  Add /modify classes and attributes

      • Implement APDM Abstract Tables and Core Tables

    Compliance and interoperability l.jpg
    Compliance and Interoperability

    • The purpose of APDM is to capture the ‘behavior’ of pipeline events, features and objects within an geodatabase object model

    • The purpose of APDM 4.0 abstract, metadata and core classes is to provide a standard for judging APDM compliance to allow true interoperability between vendor applications and data models

    • Interoperability could be assessed by development of a standard set of editing, reporting and analysis applications that could be applied to any APDM geodatabase

    Current status of the apdm l.jpg
    Current Status of the APDM

    • Yearly cycle

      • Accrual of ideas and feedback – ESRI UC  Gita Oil & Gas (Summer to Fall)

      • Technical Committee develop new aspects of model (Fall through Winter  ESRI PUG)

      • Model Release (Spring  ESRI UC)

  • Planned Events

    • APDM Pre-Conference Workshop – Saturday, August 12th


  • Scheduled release of proposed changes (V4.0)

    • Logical Model Poster, Physical Model UML (Visio 2002 format) available from

    • White paper will be released in sections over the next 2-3 weeks for review up until 05/2006
