Hi folks,                                       Thursday (11 March 2004)

[per our review at PWG face-to-face in San Jose in February 2004]

I have just posted a revised Resource XML Schema v0.30, which validates
without warnings using XML SPY 2004, XRay 2.0, and XSV 2.5 (the free XML
Schema Validator) and is posted at:

    ftp://ftp.pwg.org/pub/pwg/wbmm/schemas/resource-20040311.xsd

Below are:  (a) change log; (b) use models; (c) excerpts.

Action:  propose additional elements for Font resources (Ira).

Cheers,

------------------------------------------------------------------------
[changes from v0.20 to v0.30]

(1) Minor editorial fixups;

(2) Corrected 'ResourcePersistenceType', changing duplicate 'Permanent'
    to 'ReadOnly' (per 'StorageType' in RFC 2579);

(3) Corrected 'ResourceDocumentFormats', changing to be multi-valued as
    intended;

(4) Added 'ResourceOwner' (required), per PWG review in February;

(5) Added 'ResourceOwnerVCard' (optional), for owner contact info

(6) Added 'ResourceAccessMode' (required), with POSIX style permissions,
per PWG review in February;

(7) Added 'ResourceAccessDate' (optional), for resource aging/cleanup;

(8) Added 'ResourceJobURIs' (optional), per PWG review in February.


------------------------------------------------------------------------
[use models for Resource Schema]

(1) Fleet Management Printer Monitor
    - reads list of 'ResourceFirmware' once at startup
      and subscribes to Printer/Job/Resource alerts
    - reads 'ResourceState' and 'ResourceDataPresent' periodically
    - updates Resources, as required by specific alerts

(2) Local Operator Printer Monitor
    - reads list of all Resource types once at startup
      and subscribes to Printer/Job/Resource alerts
    - reads 'ResourceState' and 'ResourceDataPresent' periodically
    - updates Resources, as required by specific alerts

(3) Accounting Printer Monitor
    - TBD (a Resource may be either Service/Device or Job scope)
    - see new 'ResourcePersistence' element
