Hi folks, Tuesday (9 September 2003)
Below is a second draft of section 10 "Conformance" for the PSI Spec,
revised after our partial review at today's PSI telecon.
Dave Hall now plans to get a completed draft of the PSI spec out by 26
September, for review at the PWG face-to-face in New York on 7 October.
Changes to section 10.1 from first draft (26 August):
(1) Added new sentence to first paragraph (about documentation);
(2) Moved the first two requirements (documentation) in section 10.1
to a new paragraph for product literature recommendations;
(3) Added new requirements and recommendations for XML and WSDL;
(4) Added three new 'Rationale' paragraphs to section 10.1
(explaining the choices of requirement versus recommandation);
(5) Rewrote several requirements and recommendations for clarity.
Comments?
Cheers,

10. Conformance
This section specifies the conformance requirements (necessary for basic
interoperability) and conformance recommendations (useful for improved
interoperability) for all implementations of the PSI/1.0 protocol. This
section also specifies the conformance recommentations for PSI product
literature (useful for informed customer purchasing decisions).
10.1 PSI/1.0 Common Conformance
The following common conformance REQUIREMENTS apply to every PSI/1.0
implementation (Client, Print Service, or Target Device). Every PSI/1.0
implementation:
(1) MUST support (produce and consume) valid [XML1.0] documents;
(2) MUST support (publish URLs for) valid [WSDL1.1] interfaces;
(3) MUST support (produce and consume) valid [SOAP1.1] messages;
(4) MUST support the [HTTP/1.1] binding of [SOAP/1.1];
(5) MUST support the Printer Object and all mandatory elements,
as defined in section 7.1;
(6) MUST support the Job Object and all mandatory elements,
as defined in section 7.2;
(7) MUST support the Document Object and all mandatory elements,
as defined in section 7.3;
(8) MUST support pwg-psips and pwg-psitd URL schemes for Target Devices,
as defined in section 8.2.4;
(9) MUST support the http URL scheme for References,
as defined in section 8.3.1.
Rationale: Customers should be able to purchase PSI-based products
with basic interoperability guaranteed for those PSI products.
The following common conformance RECOMMENDATIONS apply to every PSI/1.0
implementation (Client, Print Service, or Target Device). Every PSI/1.0
implementation:
(1) SHOULD support [XML1.1] or later XML versions;
(2) SHOULD support [WSDL1.2] or later WSDL versions;
(3) SHOULD support [SOAP1.2] or later SOAP versions;
(4) SHOULD support non-HTTP bindings of [SOAP1.1] or later SOAP
versions;
(5) SHOULD support device discovery via the PSI Service Root URL
as defined in section 5.1;
(6) SHOULD support device discovery for specific supported environments,
for example using [SLP2.0];
(7) SHOULD support secure sessions over [TLS1.0] or later TLS versions,
as defined in section 5.2;
(8) SHOULD support the ipp URL scheme for Target Devices,
as defined in section 8.2.5;
(9) SHOULD support the ftp URL scheme for References,
as defined in section 8.3.2.
Rationale: Customers should be able to purchase PSI-based products
with improved interoperability probable for those PSI products.
The following common conformance RECOMMENDATIONS apply to product
literature. All products that claim PSI/1.0 conformance:
(1) SHOULD publish the role-independent checklist of conformance claims,
as defined in applicable paragraphs of this section 10.1 above,
in installation, packaging, or other literature (e.g., Web pages);
(2) SHOULD publish the role-specific checklist of conformance claims,
as defined in applicable sections 10.2, 10.3, and/or 10.4 below,
in installation, packaging, or other literature (e.g., Web pages).
Rationale: Customers should be able to purchase PSI-based products
with specific interoperability verified for those PSI products.
10.2 PSI/1.0 Client Conformance
The following conformance REQUIREMENTS apply to a PSI/1.0 Client.
Every PSI/1.0 Client implementation:
(1) MUST support the client role in the QueryEndPointsInterface,
for access to PSI/1.0 Print Services and PSI/1.0 Target Devices,
as defined in section 5.3;
(2) MUST support the client role in the ServiceCapabilitesInterface,
for access to PSI/1.0 Print Services and PSI/1.0 Target Devices,
as defined in section 5.4;
(3) MUST support the client role in the JobControlInterface,
for access to PSI/1.0 Print Services and PSI/1.0 Target Devices,
as defined in section 5.5.
10.3 PSI/1.0 Print Service Conformance
The following conformance REQUIREMENTS apply to a PSI/1.0 Print Service.
Every PSI/1.0 Print Service implementation:
(1) MUST support the client role in the QueryEndPointsInterface,
for access to PSI/1.0 Print Services and PSI/1.0 Target Devices,
as defined in section 5.3;
(2) MUST support the client role in the ServiceCapabilitesInterface,
for access to PSI/1.0 Print Services and PSI/1.0 Target Devices,
as defined in section 5.4;
(3) MUST support the client role in the JobControlInterface,
for access to PSI/1.0 Print Services and PSI/1.0 Target Devices,
as defined in section 5.5;
(4) MUST support the server role in the QueryEndPointsInterface,
for access from PSI/1.0 Clients and PSI/1.0 Target Devices,
as defined in section 5.3;
(5) MUST support the server role in the ServiceCapabilitesInterface,
for access from PSI/1.0 Clients and PSI/1.0 Target Devices,
as defined in section 5.4;
(6) MUST support the server role in the JobControlInterface,
for access from PSI/1.0 Clients and PSI/1.0 Target Devices,
as defined in section 5.5;
(7) MUST support the server role in the TargetDeviceSupportInterface,
for access from PSI/1.0 Target Devices,
as defined in section 5.6.
10.4 PSI/1.0 Target Device Conformance
The following conformance REQUIREMENTS apply to a PSI/1.0 Target Device.
Every PSI/1.0 Target Device implementation:
(1) MUST support the client role in the QueryEndPointsInterface,
for access to PSI/1.0 Print Services,
as defined in section 5.3;
(2) MUST support the client role in the ServiceCapabilitesInterface,
for access to PSI/1.0 Print Services,
as defined in section 5.4;
(3) MUST support the client role in the JobControlInterface,
for access to PSI/1.0 Print Services,
as defined in section 5.5;
(4) MUST support the server role in the QueryEndPointsInterface,
for access from PSI/1.0 Clients and PSI/1.0 Print Services,
as defined in section 5.3;
(5) MUST support the server role in the ServiceCapabilitesInterface,
for access from PSI/1.0 Clients and PSI/1.0 Print Services,
as defined in section 5.4;
(6) MUST support the server role in the JobControlInterface,
for access from PSI/1.0 Clients and PSI/1.0 Print Services,
as defined in section 5.5;
(7) MUST support the client role in the TargetDeviceSupportInterface,
for access to PSI/1.0 Print Services,
as defined in section 5.6.
