Greetings,
Here are a number of points of feedback on the IPP 3D Printing extensions draft in PWG Last Call (http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ipp3d10-20161114.pdf <http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ipp3d10-20161114.pdf>) - apologies that I haven't submitted these earlier:
Page 10, line 267: "extrude ABS and/or PLA filaments" might be better phrased as "extrude filaments of ABS, PLA, or other substances"
Page 10, line 271: "Discovery of 3D Printers is based on..." perhaps should be "Discovery of IPP 3D Printers is based on..."
Page 12, section 2.5: the URL highlighting seems to be inconsistent - only one is in blue with an underline
Page 12, section 2.5: 3MF isn't listed here as an organization, but ought to be?
Page 13, line 347 / 350 / 352 / etc.: The reference doesn't seem to be a bookmark that can take the reader to the reference listing
Page 13, line 357: PDF isn't listed as an existing specification
Page 13, line 358: "...document should define IPP attributes..." changed to be "...document defines IPP attributes..."
Page 22, line 559: "DNS-SD based Discovery" might instead be "DNS-SD for service advertisement and discovery". Also, not quite sure why "Discovery" is capitalized here...
Page 22, line 573: Some weird pagination stuff going on - lines 574-576 should be on page 22, and Table 2 should be on possibly page 22 or maybe page 23. But all the whitespace on page 23 seems to be a formatting glitch.
Page 24, line 586: "ASSIGN OID HERE"? Is it time to assign the OID?
Page 25, line 603: Should "[RFC3510] and IPP-USB [IPP-USB]" be "[RFC3510] and/or IPP-USB [IPP-USB]"?
Page 34, line 729: If "materials-key" is required, then "printer-strings-uri" should also be required, but it isn't listed in table 5 / section 6.5
Page 35, line 759: If "materials-key" is required, then "printer-strings-uri" should also be required, but it isn't listed in table 5 / section 6.5
Page 44, line 979: Is there any requirement as to the document format of the images available at this URI?
Page 54, section 13.4: Shouldn't the 3MF Consortium be handing the registration of the "media/3mf" media type?
Page 54, line 1338: The type name "media/3mf" isn't consistent with the type name listed in table 2 ("model/3mf"). Which is correct?
Thanks for the hard work, Mike and all contributors!
Smith
