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 orchestration (expand the meaning) and the modeling and interface
of distributed imaging systems.
The PWG Multifunction Device (MFD) Working Group has been combined with the Semantic Model
Working Group.
The PWG Semantic Model versions are as follows:
Semantic Model version 1.0 – Print related semantics only.
Semantic Model version 2.0 – Expansion of the Semantic Model to include all of the multifunction
services offered by a network attached MFD.
Semantic Model version 3.0 –Expand the Semantic Model to include new objects and elements needed
by Cloud and Mobile environments, which can be described as distributed imaging systems.
The goal of the Semantic Model 3.0 project is to develop specifications for the following topics:
(a)Transform Service – Semantic Model and Service Interface – (wd-smtransform01-yyyymmdd) –
Complete the transform service specification deliverable initially begun by the Multifunction Device
(MFD) Working Group.
(b) PWG Semantic Model v3.0 (SM3) – (wd-sm30-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.

(c) Mapping Related Standards to PWG PJT v1.0 (PJTMAP) – (wd-smpjtmap10-yyyymmdd) –define in a
fully approved PWG specification the mapping of job ticketing elements from other well-known
standards environments to the PWG PJT

Objectives:
• Microsoft PrintTicket – frequently referred to as WS-Print
• CIP4 JDF Interoperability Conformance Specification (ICS) for Integrated Digital Printing (IDP)
• Adobe PostScript Printer Definition (PPD)
(d) Mapping Related Standards to PWG PJT v2.0 (PJTMAP) – (wd-smpjtmap20-yyyymmdd) –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)
(e) CWMP Printer Data Model – (wd-smcwmpprint10-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;
(f) Semantic Model Orchestration v1.0 – (wd-smorchestration10-yyyymmdd) – define an abstract model
of how digital document processes can be integrated with the services defined in the PWG Semantic
Model
(g) Resource Service
(h) PWG Imaging Job Ticket
 OOS-1. Do not define any service management or job operations for Imaging Systems that are not
directly network connected.
 OOS-2. Do not define any new document formats to be implemented in network Imaging Systems.
 OOS-3. Do not define any new workflow or orchestration languages.
 OBJ-1. Define management requirements, use cases and architectural model for Semantic Model 3.0.
• OBJ-2. Define consistent names and semantics for these Semantic Model 3.0 objects that can be
accessed through any supported network protocol.
• OBJ-3. Define a companion set of XML Schema and WSDL files for the Semantic Model 3.0.

• OBJ-4. Define a set of mappings from related standards to the PWG Imaging Job Tickets.
• OBJ-5. Define one or more mappings to other standard management protocols or data models (e.g.
CWMP Printer).
