Hi folks,                                     Thursday (22 January 2004)

[per our review at yesterday's WBMM telecon, further review of last IPP
Resource object draft, and various IETF MIBs]

I have just posted a revised Resource XML Schema v0.20, 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-20040122.xsd

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

To do:  propose additional elements for Font resources (Ira).

Cheers,
- Ira

[changes from v0.10 to v0.20]

(1) Minor editorial fixups;

(2) Deleted the complicated state 'stopped' from 'ResourceStateType',
    per Tom Hastings comments from CIP4 JDF experience in December 2003;

(3) Corrected modelling from order-dependent parallel attributes in IPP
    Resource object for resource data by creating 'ResourceData' group:

    <xsd:element name="ResourceData">
      <!-- ResourceData - group -->
      <xsd:complexType>
        <xsd:sequence>
          <xsd:element ref="ResourceDataURI"
            minOccurs="1" maxOccurs="1"/>
          <xsd:element ref="ResourceDataFormat"
            minOccurs="1" maxOccurs="1"/>
          <xsd:element ref="ResourceDataFormatVersion"
            minOccurs="0" maxOccurs="1"/>
          <xsd:element ref="ResourceDataCompression"
            minOccurs="1" maxOccurs="1"/>
          <xsd:element ref="ResourceDataKOctets"
            minOccurs="1" maxOccurs="1"/>
          <xsd:element ref="ResourceDataPresent"
            minOccurs="1" maxOccurs="1"/>
        </xsd:sequence>
      </xsd:complexType>
    </xsd:element>

(4) Added 'ResourceDataFormat' and 'ResourceDataFormatVersion' elements
    to 'ResourceData' group (e.g., 'application/pdf' and 'PDF-is/1.0'
    for a logo), per Jerry Thrasher at WBMM telecon on 21 January 2004;

(5) Moved 'ResourceDataPresent' element from 'ResourceStatus' group
    (single-valued) to 'ResourceData' group (multi-valued),
    for correct object modelling;

(6) Added 'ResourceCopyright' element to 'ResourceDescription' group,
    for support of intellectual property notices (e.g., for a font);

(7) Added 'ResourceVersion' element to 'ResourceDescription' group,
    for support of version notices (e.g., for a firmware build);

(8) Added 'ResourceDocumentFormats' element to 'ResourceDescription'
    (e.g., 'application/pdf' for a font), per IPP Resource object;

(9) Added 'ResourceData' group (may be multi-valued) to end of
    'ResourceDescription' group, for correct object modelling;


------------------------------------------------------------------------
[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
