Agenda:
(1) PWG IP Policy and Minute Taker
(2) Approve Cloud minutes from February concall

cloud-concall-minutes-20140224.pdf)
(3) Consider IPP SIX Cloud Model comparison
(ftp://ftp.pwg.org/pub/pwg/cloud/white/Cloud-IPPSIX_Compare_20140321.docx)
(4) Review updated Draft
ftp://ftp.pwg.org/pub/pwg/cloud/wd/wd-cloudimagingmodel10-20140305.pdf,
addressing the following
Although (we hope) that this document is nearing prototype status, there are
several question that have arisen, or that I have, that should be addressed.
1. There is a requirement that the Cloud Imaging System maintain a
log in the format of the PWG Common Log Format.
a. Does the Cloud System retain the log or do the individual Cloud
Services?
b. Are the job events and parameters in the PWG Common Log Format Spec
sufficient for a Cloud Service/System?
2. It was requested that DocumentFormatAccepted and
CompressionAccepted be added as optional elements to the FetchDocument
operation. The terms are derived from IPP and do not appear in the Semantic
Model. It is understood that these are "preferred" values, not supported
values.
a. Should "preferred" values be added to the Semantic Model?
b. The model requires that the Proxy communicate the significant
elements and values of a local service (Accessible Element Set) to the
corresponding Cloud Service and update them as necessary. Therefore
preferred as well as supported values would be known to the Cloud Service.
Why should they be included in specific FetchDocument requests?
c. Or do we have a misunderstanding or disagreement with respect to
communicating the Accessible Element Set of Local Service capabilities and
description elements to the Cloud Service?
3. The Model description should refer to elements in the Semantic
Model, not IPP.
a. Should the Cloud Model explicitly identify Semantic Model elements
to be included in Operations Requests and Responses? This may require
defining new elements for inclusion in SM3.
b. Is it necessary/desirable to ensure inclusion of elements
corresponding to all IPP SIX attributes in IPP versions of the operations?
(not include a mapping in the document, but certainly generating one in a
worksheet)
4. It was requested that the GetJobElements operation be added to the
Proxy/Cloud interface, presumably to allow the Proxy to maintain a Job Log.
Although the intent of this operation is that same as for the
GetJobElements operation in the Client-Cloud interface, the access policy
restrictions are different. Specifically, for the Proxy interface, the Cloud
Service must deny access if the requested job is not one that that Cloud
Service has provided to the identified Local Service.
a. Are there other potential access restrictions as well for the Proxy
version?
b. Should the Proxy interface version of this operation have a
different name, so that defining the access and potential error response
information, which is different for the proxy version, does not overly
complicate the description of the operation?
Thank You,
Bill Wagner
