Title:

 GML 3.2 implementation of XML schemas in 07-000


Source:

 CSIRO

Work item code: 
Category:

Other

Date:  2008-08-25

 B
Use one of the following categories:
F (Critical correction)
A (corresponds to a correction in an earlier
release)
B (Addition of feature),
C (Functional modification of feature)
D (Editorial modification)

Detailed explanations of the above categories can
be found in the TC Policies and Procedures.

Reason for change:

 A GML 3.2 binding of the SensorML schemas is required for applications that
wish to use the current version of GML 3.2. It is also necessary to underpin an
orderly revision process for SensorML and SWE Common, in which
implementation specifics are handled separately from functional changes.

Summary of change:  1. Add ANNEX E "GML 3.2 XML Schemas for SWE Common (Normative)"
containing the schema documents in the accompanying zip document
Proposed namespace http://www.opengis.net/swe/1.0/gml32
Dependencies
- GML 3.2 http://www.opengis.net/gml/3.2
2. Add ANNEX F "GML 3.2 XML Schemas for SensorML (Normative)" containing
the schema documents in the accompanying zip document
Proposed namespace http://www.opengis.net/sensorML/1.0/gml32
Dependencies:


http://www.opengis.net/gml/3.2
- SWE Common http://www.opengis.net/swe/1.0/gml32
- GML 3.2

Consequences if
not approved:

 1. GML 3.2 applications incompatible with SensorML and SWE Common
2. Confused process for functional upgrades

Abstract specifications
Best Practices Document

 The strategy of issuing GML 3.2 bindings of the current schema, separate from
upgrades to the model, appears to be consistent with recent updates to OGC's
versioning and namespace policies.
The details of the namespace pattern have been discussed with Clemens Portele
and Paul Daisey.
One minor issue that emerged is that use of the schema/@version tag may be
improved. Per OGC policy the namespace name shall be changed for both major
and minor upgrades. This means that the namespace name is the key identifier
for a schema, and the version attribute can be used to supplement this with the
bug-fix number, rather than reproducing information encoded or implied by the
namespace name.
