Current Status

  • The PWG SM Working Group has been on

hiatus since the publishing of the PWG SM and associated Schema.

  • There is work from other PWG work groups that

could to be incorporated in an update to the PWG SM (e.g. WIMS, Counters).

  • The PWG SM deals only with a data model and

not with specific application use or a protocol

  • mapping. However an XML schema is included.

Inclusion of Subunit semantics

  • There is currently no access to subunits of

a print device since the SM describes a print service

  • The PWG has modeled the subunits of a

printer device in the Printer MIB.

  • Should the PWG SM Model be extended

to include the subunits?

Extension to MultiFunction Devices

  • The PWG SM currently only covers a

printer service.

  • We would like to incorporate other services

that are available in a MultiFunction Device in the SM

  • The WIMS Working Group has modeled a

Multifunction Device

  • Should we extend the PWG SM for

MultiFunction Devices?

printer service. We would like to incorporate other services that are available in a MultiFunction Device in the SM

Abstract Job Definition

  • The PWG SM definition of a Job is Print

Service Specific

  • The PWG SM may be extended to

MultiFunction Devices

  • Should a superclass of the print job be

defined?

  • Should subclasses of the abstract job be

defined for each service?

PWG SM and Management Using Web Services (MUWS) (e.g. WSDM, WS-Management)

  • Currently the PWG is working with the

DMTF to align CIM and the PWG MIBs and PWG SM.

  • Will a PWG defined “Dialect” be able to be

directly used in a MUWS environment?

  • Should we be working directly with

WSDM/WS-Management/W3C to adapt the PWG SM to those environments?

RDF Schema for PWG SM vocabulary

  • In a MultiFunction Device there is no way to

describe the relationships/dependencies between the services and subunits or between individual services.

  • RDF provides a simple way to make statements

about resources (Subject, Predicate, Object)

  • Web Ontology Language (OWL) provides a way to

provide richer semantics of resources (e.g. cardinality, keys, unions, intersection, instance equality)

  • Should we be looking at an RDF/OWL mapping of

the PWG SM?

JDF Office alignment

  • JDF Office Printing is a subgroup of JDF Digital Print

– JDF Digital Print focused on the needs of Print on Demand and borrowed from the PWG SM (IPP) – Digital Print has a work item for an Application Note for a mapping of IPP to JDF

  • Office Printing is targeted at black and white and limited

color digital networked printing systems typically used within an office environment.

  • JDF job tickets sent from the applications to the device are

complete and do not require further processing before execution – and do not require an intermediate controller

  • Covers messaging format an subset of Digital Print, and IPP,

that covers submission and simple finishings (e.g. staple collate)
