[IPP] Don't redefine Hardcopy Document

Pete,

The point of the discussion in the SM and IPP WGs is not to redefine what a hardcopy document is (although I would like to generalize what was put in 5108.01 since it ties them to specific services), but to include the definition of it and the corresponding (Hardcopy) Document Object (the digital representation of the hardcopy document) in the SM and IPP specifications.

Comments inline, but I'll make sure we include this in our discussions on Thursday...

In the PWG Semantic Model Documents are objects with references to document content that is an electronic document representation (e.g.  PDF, JPEG, PCL, vendor specific).  These representations have a type using MIME media types (See rfc2911 section 3.2.1.1). 

This is the difference between a Hardcopy Document and a Hardcopy Document /Object/. We need to define the latter and not the former.

For a FAX service we needed to represent the historical FAX paradigm of FAXing a hardcopy document.  It is similar to a Send-URI but constrained to a reference to document content being obtained via the MFD’s scanner subunit.  Note that a mobile device that acquires an image from a hardcopy document would not issue an Add-Hardcopy-Document to the MFD.  The mobile device would use the Send-Document or Send-URI based on how the document content would be transferred to the target MFD.

I disagree - mobile devices can and are used as a front-end to the MFD today. The hardcopy document may, in fact, be loaded in the MFD.  The mobile device can scan and then send the scanned data to the MFD /or/ it can simple create a job that references the loaded hardcopy document to avoid the intermediate data transfers.  And given that the scan destination semantics require some form of intermediate storage, I would argue that mobile devices would prefer to use Send/Add-Hardcopy-Document over scanning and submitting the scan.

Right, that is the point of our discussions - how do we model Hardcopy Document /Objects/ (digital representations of Hardcopy Documents) in the SM and IPP?  Aside from generalizing the Send/Add-Hardcopy-Document operation for multiple services, we need this for Cloud/IPPSIX to support indirect access to MFD scanners.
