The extensive changes made to the schema since the past face-to-face has had
significant effects on the "MFD Overall" document. In addition to the
detailed changes affecting virtually all of  the schema pictures and the
elements description tables,  the apparent promotion of the "system" from a
secondary artifact to the heart of the MFD has changed the sense of the
document  from a presentation of MFD concepts and recurring elements to
primarily a system specification.  

My intent is to produce a useful document that is consistent with the PWG
Schema, and I am in favor of any change to the schema that makes for a more
appropriate and comprehensible model. I will happily make the document
changes. However, because this is a significant expansion from the "quick
overview and common terms" approach which is still evident the current
draft, I would like to  have confirmation of the schema changes and of a
proposed restructuring of the document before I go to much further.

 

Some of the issues discussed recently are:

 

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" /,
PrinterDetailedStatusMessages, PrinterMessageFromOperator, PrinterMoreInfo,
PrinterMoreInfoManufacturer, PrinterSettableElementsSupported",
ReferenceUriSchemesSupported, RepertoiresSupported, ResourcesSupported,
UserDefinedValuesSupported, etc.)


2.     In response to a question about the "relationships" diagram (and
indeed, the Functional Overview of a Multifunction Device discussion), Pete
responded:


"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.
