Re: [IPP] IPP Firmware Update Extensions v1.0 Initial draft posted for review

Smith,

Some quick feedback on the parts of the registration we didn't get to yesterday:

- 5.1.1 printer-firmware-update-support-uri (uri)

This should probably be a 1setOf to provide a URI for each update.

- 5.1.2 printer-firmware-update-urgency (type2 keyword)

If we wanted to normalize this, we could base this on the CVSS v4.0 User Guide base score which is the update severity number from 0 (lowest) to 10 (highest).  Or we could include the whole CVSS string, for example:

    8.8 (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N)

Also, we probably want to make this a 1setOf , e.g., "printer-firmware-update-cvss (1setOf octetString(MAX))", to capture the CVSS string for each update.

- Maybe add a new 5.1.x attribute "printer-firmware-update-time (dateTime | no-value)" that specifies when the printer will apply/install the firmware updates. The 'no-value' out-of-band value would indicate that updates will not be installed automatically.

- 6.1 Firmware-Self-Update

I suggest we call this operation "Update-Printer-Firmware" since we usually use verbs in operation names.

- 6.1.1 ... Request

I suggest we add "delay-update-until (type2 keyword)" and "delay-update-time-time (dateTime)" operation attributes to specify when to do the firmware update. Keywords could mirror the "job-hold-until" attribute: 'indefinite' to pause updates, 'now' to install immediately, 'night' to install during the night, and 'weekend' to install over the weekend.

- 7.1 printer-state-reasons

I recommend slightly different naming: 'firmware-update-available', 'firmware-update-failed', and 'firmware-updated-successfully' for consistency with other job/printer-state-reasons. Also, maybe add 'firmware-update-queued' for an update that is scheduled for installation?

Thanks for doing the work on this!
