jdf on one slide
JDF on One Slide
  • JDF is a Graphic Arts Job TicketData Interchange Format Specification- JDF is not an Application or System
  • JDF is encoded in XML
  • Content is referenced, not embedded
  • JDF is extensible
  • JDF is based on semantic structures defined by:
    • Adobe PJTF
    • CIP3 PPF
  • JDF Job Definition + JMF Messaging define the JDF Framework
the building blocks of the jdf framework
The Building Blocks of the JDF Framework
  • JDF Node
    • Description of a Process, Process Group or Product
  • JDF Resource
    • Description of a parameter set or physical entity
  • JDF ResourceLink
    • Link between JDF Nodes (processes) and Resources
  • JDF Capabilities Descriptions
    • Limitation of a JDF interface
  • JMF Messages
    • Real time data interchange format
the jdf node
The JDF Node
  • Description of a generic Process
    • The “Verb” in JDF
    • Do something at a given time
    • Structured container for Scheduling and Auditing
  • One JDF node type for Products and Processes
  • Less Precise Product Intent at the Job Root Node
  • Workflow Group nodes “ProcessGroup” in between
  • Detailed individual or combined Processes in the Leaf Nodes

Product Intent vs. Process Modeling
  • Goal of Product Intent Description
    • Customers view of the “thing” that he wants to have manufactured
    • Contract Negotiation
    • Process Independent
  • Goal of Process Modeling
    • Interface between production and management information systems
    • Process interdependencies

Link

ResourceLink
  • Bind a Resource to a Node
  • Define Resource Usage (input or output)
  • Link to a Subset / Part of a Resource
    • E.g. Cyan Plate of the Front of Sheet #1
    • Define the Amount
  • Allow reuse of Resources by multiple processes
    • One resource may be linked by multiple ResourceLinks
  • Defines a process network

experience with jdf
Experience with JDF

1999: Adobe, Agfa, MAN and Heidelberg form the GAT initiative with the goal of defining a job ticket for the Graphic Arts that also integrates MIS.

2000: The CIP3 Consortium takes ownership of the standard.

2001: JDF 1.0 is released.

2002: JDF 1.1 is released.

  • Ambiguities/Bugs found in implementation were removed
  • Additional Processes were added
  • Consistency between diverse areas was enhanced
