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
