Outline

• Architectural Overview of JDF

• Experience with JDF

Page 4: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

JDF on One Slide

• JDF is a Graphic Arts Job Ticket Data 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 originally defined by:– Adobe PJTF– CIP3 PPF

• JDF Job Definition + JMF Messaging +JDF Capabilities + ICS Documents define the JDF Framework

Page 5: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

JDF on Another Slide- Goals and Requirements -

• Why JDF?– Automation increases Efficiency

– Digital information reduces errors compared to paper job jackets

– Information allows for informed decisions

– We have a digital content workflow with a paper based management workflow – there is room for improvement!

• What does JDF enable?– Setup a Job in the graphic arts from the view point of:

• Technical Applications

• Management Information Systems

• Customers

– Collect data that is relevant to a Job from origination to delivery• Business Data

• Technical Data

JDF Encoding

• XML Encoding

• External references via URI/URL

• XML Schema for Data Type Definitions

• Extensibility using XML name spaces

Page 8: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

The Building Blocks of the JDF Framework

• JDF Node– Description of a Process, Process Group, Gray Box or Product

• JDF Resource– Description of a parameter set or physical entity

• JDF ResourceLink– Link between JDF Nodes and Resources

• JDF Capabilities Descriptions– Limitation of a JDF interface

• JMF Messages– Real time data interchange format

• ICS Documents– Specification of Limits of the JDF for individual purposes

Page 9: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

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 both Products and Processes

• Less Precise Product Intentat the Job Root Node

• Abstract “ProcessGroup” Nodes or “Gray Box” nodes 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” they want to manufacture

– Contract Negotiation

– Process Independent

Product Intent vs. Process Modeling

• Goal of Process Modeling – Interface between MIS and Production– Process interdependencies – Manufacturing Instruction Details

Page 12: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Gray Boxes

• Incomplete Model of a Process• The MIS View of the process

– It’s only important if it affects the cost!– Thus, parameters not affecting costs are not

important

• Exact Process execution is potentially undefined– Ordering of steps is not necessarily predefined– Detailed Work Steps may be left out

• E.g. MIS knows RIPping, but not Trapping or ColorSpaceConversion

Page 13: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Audit Objects

• Logging of Job Execution

– Actual times

• Start time

• End time

• Job Phases

• Logging of Changes

– Resources

• used 85g Paper instead of 80g

• Used Roll inventory #123, not #456

– Consumables

– Actual Amounts produced or consumed

• Status Summary • Event Log

Page 14: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Job / Customer Information

• CustomerInfo

– Map Subcontracting via Localized Customer

Information in any JDF Node

– Customer ID

– Addresses (Delivery, Invoice, …)

• NodeInfo

– Scheduling

– Deadlines

– Processing Time Estimation

Page 15: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Page 16: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

The JDF Node – Node Type

• Individual process types and their respective resources are defined: e.g.– Interpreting

– Trapping

– ConventionalPrinting

– DigitalPrinting

– Cutting

– Folding

– Verification

– Delivery

– …

Page 17: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Combination of JDF Nodes

• Don’t recreate a new Process Type for Permutations of known Processes!

• Create combinations of multiple defined processes into one process, e.g.:

• online finishing = printing + folding +cutting;

• in-RIP trapping = trapping + RIPping

• Three types of Combination Nodes

– Combined Node: All internal interfaces are hidden

• Smart multi-function device

– ProcessGroup: Internal nodes are accessible

• Without Sub elements (Gray Box)– MIS view

• With Sub elements– Workflow group in a department

– Subcontract

The JDF Node – Execution Requirements

• A Node is executable when all required input resources are available

– Serial Processing -- Standard

– Parallel Processing -- Partial Resources

– Overlapping Processing -- Pipes

– Iterative Processing -- Draft Resources

• Node dependencies allow process configuration

– A proof node can create an Approval which is needed for

the press node to operate

– Subcontracting

– Support for Partitioning – e.g. only sheet #1

• Merge back after processing– Retain information source Context

• Audits

• Modified Resources

JMF Messaging

• Real-time data interchange format• Small XML structures

– JDF is referenced via URL, not bound into message

– Idea is to minimize network traffic and delay transmission of data until it is actually needed

– Send potentially interesting information as soon as it is available

Page 46: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

JMF Messaging

• Used for:– Snapshots of Job / Device status

– Dynamic job update

– Job submission and Queue/QueueEntry handling

– Capabilities discovery

– Plug + Play bootstrapping (Future)

• Generally used within an Intranet

Page 47: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

JMF Message Families

• JMF messages fall into six categories– Command

• Receiver is instructed to take an action, or to modify the state of something

– Query• Receiver is instructed to return information about

something. No action is taken, no states are changed

– Response• Used to immediately return result of command or

query• Synchronous messaging – command/query and

response are exchanged on same open connection

Page 48: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

JMF Message Families

• JMF message categories (cont’d)– Acknowledge

• Used to return the result of a command after some time has passed

• Asynchronous messaging – empty response returned immediately on same connection as command with indication that Acknowledgement will be sent later

– Signal• Used to send notifications of events or change in status• Typically result of a query with a subscription embedded in it• Subscription sets up persistent channel

– Registration• Request for commands• Used to set up triangular workflows• E.g. MIS tells prepress to send a Command to Press

Page 49: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Example – SubmitQueueEntry message:

<JMF DeviceID="SP013" SenderID="MIS1“TimeStamp="2006-05-05T12:32:48-06:00">

<Command ID="m3829" Type="SubmitQueueEntry">

<QueueSubmissionParamsURL="http://jobserver/getJob?

job=10047"

ReturnJMF="http://jobserver/jmfservice"

Priority="50"/>

</Command>

</JMF>

Page 50: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

JMF Message Types

• Examples of JMF message that fall within the six categories– Command

• SubmitQueueEntry, AbortQueueEntry, ReturnQueueEntry, HoldQueue, ResumeQueue

– Query• KnownControllers, KnownDevices, Status

– Response• Various related to various commands/queries

– Acknowledgement• Various related to various commands/queries

– Signal• Status, Resource, Occupation

– Registration• Resource

JDF Capabilities Ahead

• Interoperability

• Capabilities

• Workflow

• PPD’s and Schemas

• Capabilities Theory

• Capabilities Overview

Page 52: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

It’s all about Interoperability !!!

If you don’t know about capabilities, you won’t be able to “interoperate”…

Page 53: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

It’s all about Interoperability!!

But if you do, you can use the right tools…

Page 54: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

What are “Capabilities”?

Capabilities allow actors in the workflow to determine what some other actor can do...

Page 55: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

What are Capabilities?

Of course, there’s no requirement that any of the actors actually

be people…

Page 56: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Who are the actors?

• Job submission utilities (both to a print shop and within the print shop)

• Print shops• MIS systems• Prepress workflow managers• Applications• Individual pieces of equipment• Operators of offline equipment• And the list goes on…

Page 57: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

What can Capabilities be used For?

• Determining what products a print shop could produce.– Allows the creation of JDF Intent (product descriptions).

• Determining what equipment is available in a shop.– Allows MIS systems to take JDF Intent and determine

production steps to produce job.

• Creating a UI to allow configuration of job processing for a piece of equipment or application.

• Preflighting a JDF before processing by a JDF consumer.

Details Ahead!!

Page 64: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

What about PPDs and Schemas?

PPDs (PostScript Printer Driver)• Provide basic capabilities information

about a printer

• Allow printer options to be configured by specifying PostScript snippets

• Provide a simple constraints mechanism for UI

• Allow controls to be localized (but typically just for the “advanced” dialog)

Page 65: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

What about PPDs and Schemas?

Schemas• Describe the aggregated capabilities of JDF

(processes & resources)

• Do not support constraints definitions

• Do not support localizations

• Do not allow a device to specify a subset of the aggregated capabilities

Page 66: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

So what are Capabilities?

• XML-based

– Of course…

– The capabilities description directly reflects the

structure of the JDF itself.

• Constrains a device implementation against the schema

– Either the JDF schema or an extension schema

– Does not require the schema to be used to work

Remember, the schema

only specifies the aggregated

capabilities of JDF

Page 67: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.
Page 68: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Capabilities Theory

JDF defines a Capabilities Model based on....

– A Device is the “Thing” that executes one or more JDF Nodes

– A JDF Node is defined by its resources + resource

links

• e.g.: A Press has a set of allowed Media and a set of

press parameters

Page 69: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Capabilities Theory

JDF Parameters are either.....• independent of one another, or• can be expressed as a list of allowed independent

sets– e.g. a Scanner can scan at 1000 dpi grayscale, or 500 dpi color

• May be further constrained by logical boolean expressions– The Device can print Duplex– The Device can print Transparencies– Setting Duplex and Transparency at the same time is

constrained

Page 70: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Capabilities Theory

• Performance may be specified– Maximum + Average– Depending on further Job parameters

• Allow specification of current and persistent capabilities

• Define defaults and (un)/supported features• JMF messages for plug and play in heterogeneous

environments• Specify Localization

Capabilities Overview

Feature Macros (JDF 1.2)

• Allows a set of multiple JDF controls to be represented by a single abstract control in a user interface.

– ScannerQuality: (draft, good, best)

– sets resolution, color mode, …

Page 73: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Capabilities Overview

Localizations (JDF 1.2)• Feature names and individual values can be

localized (even true and false)• Also used with constraints to provide localized

descriptions (for UI) of the error described when the constraint test fails

Page 74: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Capabilities Overview

Feature Availability (JDF 1.2)

• The feature is installed on the device and is available for use.

• The feature has not been installed on the device.

• The feature has been installed on the device, but may not be used until licensed.

• The feature is installed and licensed on the device, but has been disabled.

Page 75: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Capabilities Overview

UI Hints (JDF 1.2)

• Feature grouping

• Unit type

– Angle, length, weight,…

• Whether a feature should be displayed– The feature should be displayed.– The feature should not be displayed.– The feature should be displayed only for administrators.– The feature should be conditionally displayed.– The feature should be displayed only

in vendor support situations.• Icons to represent the device

Page 76: Welcome to the Quebec JDF Tutorial. Tutorial Session Speakers Henny van Esch - Optichrome Rainer Prosi- Heidelberg.

Capabilities Overview

• JMF (Job Messaging Format) capabilities

– Which JMF messages are supported

– Specifics for each message

• JMF Bootstrapping for Device Discovery

History of 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 enhanced2004: JDF 1.2 is released

– More additional processes

– Even more mature and consistent 2005: First set of ICS documents are published

– JDF 1.3 is released

Interoperability Conformance Specifications

• Define a set of Interoperability Conformance Specifications – ICS

– The term “JDF Compliant” does not immediately imply

that two arbitrary applications will communicate.

• Sending RIP instructions to a Folding Machine is not useful…

– Two applications that comply with a given ICS will

communicate in a meaningful way.

– Product Certification will be based on ICS Compliance

• Avoid multiple, incompatible JDF Dialects

ICS documents

• Provide the basis for certification

• Ensure that products MUST read / write / accept certain conditions

– Interoperability between applications

• Limited functionality in the initial ICS versions

– Additional functionality is optional but not certifiable

– Multiple levels

– More functionality will be added in future ICS versions

Read – Write Conformance

• JDF Specification: Describes the valid cardinality of parameters in a JDF or JMF instance

• ICS: Specifies conformance requirements for an application or device

– W: Must write. The application only conforms, if it always writes the parameter

– W?: May Write. Not a Conformance requirement – W: Conditional write conformance. External conditions exist

the require an application to write.– !W: Must NOT write. The application does not conform, if it

writes the parameter.

– R: Must read. The Information must be “parsed and appropriately processed”

– R?: May Read. Not a Conformance requirement
