The following table defines how to convert the administration data of CIP3. In some situations, it may not be clear

whether or not conversion is necessary. Processes such as CIP3AdmFilmType, for example, contain limited

D.3.2 Preview Images

In PPF, preview images are coded as an in-line image. This is not possible in version 1.0 of XML, so JDF uses the

URL attribute within the Preview resource (see Section 7.2.111 Preview ), which points to an external PNG file.

The following table shows how to translate the PPF preview structure to the PNG header. Use the partition feature

to assign a preview image to a specific separation and surface.

In CIP3, the two types of measuring fields are specified by an entry of the data dictionary in the

CIP3PlaceMeasuringField command. In JDF, this approach is replaced by two different types of JDF elements:

CIELABMeasuringField and DensityMeasuringField. All parameters of the CIP3PlaceMeasuringField

command are merged into these elements. See the following tables as well as Section 7.2.16

CIELABMeasuringField and Section 7.2.43 DensityMeasuringField for further information. All PPF entries that

are not explicitly listed in the following tables can be directly converted. Place the originated element inside the

CIP3’s cut block structure is translated to JDF by defining Cutting processes. Since CIP3 has the ability to create

nested cut blocks, one separate Cutting process is needed for each nested block set. Simply follow the instructions

CIP3CutModel entry is not used in JDF.

D.3.7 Folding Data

When a CIP3 cut block has a folding operation defined (CIP3BlockFoldingProcedure), append a JDF Folding

process which uses the respective output Component of the respective Cutting process as an input Component.

See Folding for more information on how to translate the CIP3 folding procedure, which is used to fold the cut

block.

D.3.8 Comments and Annotations

PPF comments can either be converted to an XML comment or to a human-readable form by transforming them into

a Comment telem of the next element. In most cases, PPF comments can simply be ignored. Annotations are not

supported by JDF.

D.3.9 Private Data and Content

For your private data, you should first examine if one of the new JDF elements or attributes fits your requirements. If not,

please use the extension capabilities of JDF to express your needs. They are described in Section 3.11.

Appendix E Modeling IfraTrack in JDF

Introduction

Job tracking and production control are integral parts of a workflow system. IFRA, described in this section, has

defined a job tracking system called IfraTrack that fulfills a large number of the job tracking requirements of a

production scenario and is especially effective in newspaper production. The JDF messaging system generalizes

the IfraTrack approach, expanding its focus from a newspaper workflow to one that encompasses the entire graphic

arts industry. This appendix provides further detail about the way in which JDF expands upon the existing IfraTrack

technology.

E.1 IFRA Objects and JDF Nodes

IfraTrack traces the status of objects, and these objects are modified by processes that are only generic. JDF, on the

other hand, precisely defines process nodes that create output resources. These JDF output resources are equivalent

to IfraTrack objects, so tracking the state of a JDF node conveys a superset of the information communicated by

tracking the state of an IfraTrack. The sections that follow define the mapping of IFRA concepts to JDF concepts in

greater detail.

E.1.1 Object Identification

IfraTrack defines objects with an object path. The object path, in turn, may be a unique identifier, or UID. JDF also

supports UIDs for internal linking of objects, although these UIDs should not be exported beyond the scope of a JDF

document. External references to JDF nodes should be made the JobID/JobPartID pair. These values may be

defined by an external system, such as MIS, and can be used to uniquely track JDF nodes.

E.1.2 IFRA Object Hierarchy

IfraTrack defines an explicit hierarchy to define a newspaper, from Issue through Edition, EditionVersion, and so

on. JDF, on the other hand, defines a generic hierarchy of products containing a description attribute that allows the

products to be named. An IfraTrack-conforming JDF job consequently includes a product hierarchy with product

nodes that contain the appropriate description fields. Furthermore, the abstract IFRA Element type is mapped to the

JDF LayoutElement type.

E.1.3 Object States

IFRA defines object states that define the status of a resource, although they also define the status of the process that

defines a resource. JDF defines explicit states for both processes and resources. In addition, JDF defines a

descriptive string to denote the details of each status. The mapping is defined in the following table.

Table E.1 IFRA object states

IFRA

Object

Status

JDF Node Status

Status

Description

Waiting

Unavailable

Status prior to InProgress.

Not Started

JDF defines a test-run mode that allows generalized

preflighting. Ready is the status after TestRun.

Setup

Unavailable

A process is InProgress but not yet producing any

output.

InProgress

Unavailable

A process is InProgress.

In Progress

Cleanup

Available

A process is running after all output has been produced.

On Hold

Stopped

Unavailable

A process is active but not currently producing, as when

maintenance is run during a job.

Completed

Available

Completed

Aborted

Unavailable

Fatal Error

Unless aborted during cleanup

Page 550

E.1.4 Deadlines and Scheduling

In IfraTrack, activities may be linked to deadlines. JDF defines deadlines in the NodeInfo element of every node.

The definition of deadline values is identical.

IFRA defines an integer value for deadline level. JDF defines four explicit enumerations for DueLevel in order

to assure that devices in a heterogeneous system have the same concept of deadline level.

E.2 JMF Messages that Translate IfraTrack Messages

The messages explained in Section 5.5.2 Device/Operator Status and Job Progress Messages can be used to emulate

IfraTrack functionality. Specifically the messages:

• 5.5.2.3 Status

• 5.5.2.4 Track

Page 551

Appendix F Mapping between JDF and IPP

The mapping between JDF and IPP is specified in Appendix F in JDF/1.0 using the IDPrinting process. However,

for JDF/1.1, the IDPrinting process is deprecated. Thus for JDF/1.1, mapping between JDF/1.1 and IPP should be

done with the DigitalPrinting process and many other JDF/1.1 processes as a combined process node.
