There will be an MFD conference call at 3:00 PM EDT (12:00 PM PDT)
Thursday July 23. In preparation for this I have uploaded the latest
version of the PWG Semantic Model Schema. I contains updates based on
input from the Face to Face meeting. The updated schema is available
via the MFD web page <http://www.pwg.org/mfd> or the zip file directly
The meeting is held in accord with the PWG Intellectual Property Policy.
Note the NEW Teleconference number and access code are now used.
Please contact me if you do not have the new number and pass code.

4. Overview of recent schema changes
5. Discuss MFD Model and Overall Semantics - Interim Draft. (validate
items below before update of draft)
1. The "Print" service, following the IPP model, contained many
more elements under Description and Status than any other service. Many
of these elements appeared applicable to the MFD as a whole (and
therefore would appear under System) and/or perhaps to each individual
service. Many of these elements have now been put into the
ServiceDesciption and ServiceStatus general groups.
a) Do those elements which have been put in the general groups
reasonably apply to all services as well as to the system and, if so,
what is the relationship between System values and Service values?
(i.e., is the System value the default or the overriding value..or does
it apply only to system-specific instances)
b) Do any of the other Print Service specific elements also apply
(with the appropriate service name) to the system and/or the general
services element group? (e.g., MultipleDocumentJobsSupported,
MultipleOperationTimeOut, MultipleOperationTimeoutAction" /,
RepertoiresSupported, ResourcesSupported, UserDefinedValuesSupported,
2. In response to a question about the "relationships" diagram (and
indeed, the Functional Overview of a Multifunction Device discussion),
"When discussing Services within an MFD, that maps to Services under
Server. When we discuss Subunits within an MFD, that maps to
SystemConfigurations within System. It looks as though there is some
inconsistency as to what element represents the MFD in the schema. I am
not sure how this should be resolved. I believe there are transport
endpoints at which network services are available. For the individual
MFD Services (e.g. Print, Scan) the schema element XxxService (e.g.
Server.Services.PrintServices.PrintService) represents the active
object. For the MFD as a whole the Schema element Server.System
represents the active object. I have begun defining a Web Service for
the MFD as a whole. It seems to me that this inconsistency should be
discussed this Thursday."
3. The schema has included EM EmailIn and EmailOut as services for
some time, but we never included them in the Services interface diagram
that Pete drew up some time ago. Ira has explained that these are not
restricted to communicating images and therefore not subject to
inclusion in the overall FaxIn and FaxOut services. However, it is not
clear to me that these are MFD services any more than HTTP, FTP and PSTN
are MFD services. I would like some consensus that these are MFD
services and what makes them MFD services, and how to include them in
the Services Interface Diagram.
4. I have been restructuring the Overall document and am having
difficulty following a reasonable hierarchical structure while still
keeping the detailed elements descriptions at least close to each other.
This is my current organization. I would appreciate some discussion.
