Ira,
Given the changes, “Allocate” and “Deallocate” work for me.  Since the resource is now owned by each system will there be a way to deploy a resource across multiple systems?

Hi Pete,
Structural changes from Nancy's original SM Resource Service:
(1) No longer any Resource Service
(2) All Resources are owned by the System
(3) Improved set of Resource-level operations (Create, SendResourceData,
Install are all REQUIRED before allocation of any Resource)
(4) New "resource-state" (pending, available, installed, canceled, aborted)
replaces dubious resource leases (my original lousy idea).
Printer-scope Resources can be allocated to more than one instance
of Print Service.  We have avoided using the first-class verb "Associate"
to avoid confusion with security/access-control aspects.
A number of Resources can (usually will) be pre-installed on a System
at manufacturing time.  These can be allocated with Create-Printer (with
the operation attribute "resource-ids").  Also later implicitly allocated with
HTTP PUT request (per IPP Shared Infra Ext).  But when an Admin has
later installed a bunch of new Resources (fonts, forms, ICC profiles), we
want to use a first-class operation to allocate them to specific Printers.
For this case "Acquire" is the wrong semantic and "Release" would be
overloaded (we have avoiding ever doing this in System Service drafts).
WDYT?
Cheers,
- Ira

Ira,
‘Allocate’ sounds good to me, especially since the resource may be shared.
Thanks,
Bill Wagner

Hi,
In my editor's draft of IPP System Service, I've added two new
operations for associating Resources with Printers (in addition
to the current methods of Create-Printer and HTTP PUT as
described in IPP Shared Infrastructure Extensions):
  Allocate-Printer-Resources (printer-id, resource-ids)
  Deallocate-Printer-Resources (printer-id, resource-ids)
Particularly for systems with multiple Print Service instances,
these would allow more flexible Resource management.
I propose the verb "Allocate" (as in memory allocation) rather
than "Assign" to avoid confusion with "output-device-assigned".
WDYT?
Cheers,
- Ira
