Problem Statement:
The PWG Semantic Model (SM) Working Group was chartered in August 2002 to extract the print
semantics from the previously defined Internet Printing Protocol and to produce a model, which was
independent of any particular binding. The group did fulfill the work outlined in its charter and it
produced the PWG Standard “PWG Candidate Standard 5105.1-2004 - PWG Semantic Model” and a
Semantic Model v1 Schema as well. When this work was completed in January of 2004, the Semantic
Model Working Group became inactive.

The PWG Multifunction Device (MFD) Working Group was chartered in May 2007 to expand the existing
PWG Semantic Model beyond the semantics for just print and to add into the model the semantics
needed to represent all of the different multifunction services available in a network attached MFD. The
group produced a series of standards from its inception in 2007 through 2012.
 PWG 5108.01-2011 - MFD Model and Common Semantics Version 1.0
 PWG 5108.02-2009 - Network Scan Service Semantic Model and Service Interface Version 1.0
 PWG 5108.03-2009 - Network Resource Service Semantic Model and Service Interface Version 1.0
 PWG5108.04-2011 - Copy Service Semantic Model and Service Interface Version 1.0
 PWG5108.05-2011 - FaxOut Service Semantic Model and Service Interface Version 1.0
 PWG5108.06-2012 - System Object and System Control Service Semantics Version 1.0
 PWG5108.07-2012 - PWG Print Job Ticket and Associated Capabilities Version 1.0
The PWG Multifunction Device (MFD) Working Group also produced a Semantic Model v2 Schema,
which extended the original work of the Semantic Model Working Group to contain all of the new
objects and elements needed to fully define the capabilities of a network attached MFD.
With the advent of both mobile and cloud based printing applications, the scope of PWG activities has
been expanded further to include workflow and the modeling and interface of distributed imaging
systems.
Though unintended, the PWG has found that some reviewers of published PWG Multifunction Device
(MFD) Working Group specifications have mistakenly concluded there are unique semantics for different
services because the group produced separate specifications to describe the attributes of a particular
service rather than a single document with chapters describing the different services included within the
overall PWG Semantic Model.
To properly support the needs of the Cloud and Mobile environments and to reduce the confusion
inadvertently caused by the previous set of PWG Multifunction Device (MFD) Working Group authored
Semantic Model specifications, the PWG has undertaken the following actions:
1. The PWG Semantic Model Working Group has been reactivated.
2. The PWG Multifunction Device (MFD) Working Group has been made inactive. All of its previous work
will be supported by the reactivated Semantic Model Working Group and the previous work from both
the Semantic Model Working Group and the Multifunction Device (MFD) Working Group will be merged
into a coherent single specification.
3. The accepted PWG Semantic Model version numbering scheme will be as follows:
Semantic Model version 1.0 – Print related semantics only.
Semantic Model version 2.0 – Expansion of the Semantic Model through the efforts of the Multifunction
Device (MFD) Working Group to include modeling all of the multifunction services offered by a network
attached MFD.

Semantic Model version 3.0 – integration of the Semantic Model version 1.0 and 2.0 specification
documents into a single coherent version 3.0 Semantic Model specification. Expand the Semantic Model
to include new objects and elements needed by Cloud and Mobile environments, which can be
described as distributed imaging systems.

Out-of-scope:
The goal of the Semantic Model 3.0 project is to complete one draft specification from the Multifunction
Device (MFD) Working Group and to develop the following five (5) new specifications:
Transform Service – Semantic Model and Service Interface – (wd-mfdtransformmodel01-yyyymmdd) –
Complete the transform service specification deliverable initially begun by the Multifunction Device
(MFD) Working Group.
(a) PWG Semantic Model v3.0 (SM3) – (wd-pwgsemanticmodel30-yyyymmdd) – update the PWG MFD
Model and Common Semantics specification [PWG 5108.01-2011], extending the model from that of an
MFD to a more generalized Imaging System. This specification will describe the core attributes of all
Imaging Services, with attributes unique to each Service discussed in Service specific separate sections.
The Imaging Services addressed are Print, Scan, Fax-In, Fax-Out, Email-In, Email-Out, Transform,
Resource, System Control and Job Ticketing.
(b) Mapping Related Standards to PWG PJT v1.0 (PJTMAP) – (wd-mfdpjtmap10-yyyymmdd) – purpose is
to define in a fully approved PWG specification the mapping of job ticketing elements from other wellknown standards environments to the PWG PJT
• Microsoft PrintTicket – frequently referred to as WS-Print
• CIP4 JDF Interoperability Conformance Specification (ICS) for Integrated Digital Printing (IDP)
• Adobe PostScript Printer Definition (PPD)
(c) Mapping Related Standards to PWG PJT v2.0 (PJTMAP) – (wd-mfdpjtmap20-yyyymmdd) – purpose is
to expand the number of mappings initially included in version 1.0 of the specification
• Distributed Management Task Force – CIM
• AFP Consortium Mixed Object: Document Content Architecture – Presentation (MO:DCA-P)
• AFP Consortium Intelligent Printer Data Stream (IPDS)
(d) CWMP Printer Data Model – (wd-sm=cwmpprint10-yyyymmdd) – define an abstract CWMP (BBF TR069) Printer Data Model, including the algorithms for machine translation from the PWG Semantic
Model XML Schema and mapping from IPP (service) and SNMP (device) attributes for CWMP Proxy
implementations, based on BBF liaison and reviews and other public standards documents;
(e) Service Integration with Workflow Environments v1.0 – (wdmfdserviceintegrationworkflow01yyyymmdd) – define an abstract model of how digital document processes can be integrated with the
services defined in the PWG Semantic Model
 OOS-1. Do not define any compound services (e.g., Scan-To-Email, Scan-To-Fax, or Scan-To-Print).
128
129
130
131
132
133
 OOS-2. Do not define any service management or job operations for MFDs that are not directly
network connected.

Milestones:
 OOS-3. Do not define any new document formats to be implemented in network MFDs
(i.e., alternatives to TIFF, JPEG, etc.).
 OBJ-1. Define management requirements and usage models for network Print, Scan, Fax-In, Fax-Out,
Email-In, Email-Out, Transform, Resource, System Control and Job Ticketing services, jobs, and
documents.
• OBJ-2. Define an abstract architectural model of management objects and semantics for the above set
of requirements and usage models.
• OBJ-3. Define consistent names and semantics for these management objects that can be accessed
through any supported management protocol.
• OBJ-4. Define a set of abstract Print, Scan, Fax-In, Fax-Out, Email-In, Email-Out, Transform, Resource,
System Control and Job Ticketing Service Interfaces (SSI) that:
(a) are coherent with the PWG Semantic Model (PWG 5105.1);
(b) include or reference the above abstract architectural model;
(c) define abstract Print, Scan, Fax-In, Fax-Out, Email-In, Email-Out, Transform, Resource, System
Control and Job Ticketing service, job, and document management objects, operations, and
attributes; and
(d) define abstract Scan, Fax-In, and Email-In job submission operation(s) for simple
Scan, Fax, or Email-To-Storage jobs (i.e., receiving one or more physical media pages, performing
any required image processing, and storing the results to a local or remote document
repository).
• OBJ-5. Define a set of XML Schema files for the abstract Print, Scan, Fax-In, Fax-Out, Email-In, EmailOut, Transform, Resource, System Control and Job Ticketing service, job, and document objects,
operations, and attributes that are defined in the abstract Print, Scan, Fax-In, Fax-Out, Email-In, EmailOut, Transform, Resource, System Control and Job Ticketing Service Interface specifications.
• OBJ-6. Define a Web Services Binding of the abstract Cloud Imaging Model.
