I have only had a chance to give a quick look at the document and definitely do not consider it a waste of time. I found it quite useful and have linked it into the MFD page. I would like to spend a little time at the face to face to work through the confusion around the Job Ticket lifecycle. Having a top level document framing the work of modeling MFD services probably should have been the first step in the MFD group. I was already actively working print and scan in a number of forums. As we move forward with services, at least partially, built with the semantic definitions established in print and scan this overall view paper will be useful.

Subject: MFD> overall MFD considerations
At the October face-to-face, we had what I believe was a useful overview discussion of the interfaces to the various MFD services. I think that, although modeling a conceptual MFD service by service is a practical way to approach this task, there is the possibility of losing or distorting (or never having) an overall perspective. I have redrawn the interfaces diagram, provided some text, attempted a generalization of the terminology, and taken a cut at a generalized ticket life diagram. These are posted at ftp://ftp.pwg.org/pub/pwg/mfd/white/MFD_Outline_Nov_00.doc.
I have noticed some roughness in the Scan Service Terminology (I think Glen mentioned it) and a typeo:
"CrossFeed direction This is the direction perpendicular to the movement of the Hard Copy
Document or light bar of the scanner. For scanners that use a
technology other that a light bar, this is the direction along which the
image data is acquired most slowly. (See also Fast Scan direction, X
and §7.1.4) This direction is sometimes referred to as XFeed
I expect the cross-feed is the direction along which the image data is acquired most rapidly.
Also, although I thought I understood the ScanJobTicket Lifecycle diagram (Fig 5 in the Scan Service Spec), when Pete explained it, I admit that I found it confusing when I tried to extrapolate a generalized JobTicket diagram, particularly when also looking at earlier versions and at the Multifunction Device Overview diagram (fig 1) in the current spec. If this looks OK to everyone else, I will figure it out.
I would appreciate comments on the MFD Outline white paper...whether "it's a waste of time" or " it's a useful document" or whatever is appropriate in between.
