Part A to be completed once.  Iterate Part B as needed.

PART A
1. Evaluators:
         For DGIWG - Stefan Strobel – 
stefan.strobel at strobel-geoinformatics.de, Emmanuel Devys - 
Emmanuel.Devys at ign.fr,                                Dimitri Sarafinof

2. Submission: [09-146r3, OGC® Coverage Implementation Schema 1.1]

PART B
1. Requirement: General / Relationship with 19123 + Backward 
compatibility with Coverage model (UML)
2. Implementation Specification Section number: General
3. Criticality: Major
4. Comments/justifications for changes: The document submitted is both 
bringing improvements and changes to the 19123/Topic 6 model and 
significantly extending/modifying the schema proposed by GMLCOV.
The evolutions in coverage model and schema are considered of interest 
and welcome, as they clarify the 19123 model and significantly extend 
the schema proposed by GMLCOV
It is required that the coverage model is made either backward 
compatible, or to provide the replacement model otherwise. In this case, 
the requirement of providing UML models (a UML model for the revision of 
19123/AS Topic 6) is recommended as a subsequent action.

  PART B
1. Requirement: General / Backwards compatibility
2. Implementation Specification Section number: General
3. Criticality: Major
4. Comments/justifications for changes: The document submitted is not 
backwards compatible with GMLCOV (e.g. RectifiedGridCoverage). The minor 
revision number is therefore questionable.
Either provide backwards compatibility for deprecated elements or make 
it clear that CIS 1.1 is not backwards compatible by following OGC 
naming conventions calling it CIS 2.0.

PART B
1. Requirement: General / Backwards compatibility 2
2. Implementation Specification Section number: General
3. Criticality: Major
4. Comments/justifications for changes: The document submitted is not 
backwards compatible with GMLCOV (e.g. RectifiedGridCoverage).
Providing a mapping between GMLCOV (CIS 1.0) and CIS 1.1 is considered 
essential.
At a minimum a mapping between the GMLCOV schema and the CIS 1.1 schema 
for key implemented elements (in GMLCOV): GridCoverage, 
RectifiedGridCoverage, MultiPointCoverage, MultiSurfaceCoverage needs to 
be provided.
This should be supported by providing UML models (a UML model for the 
revision of 19123 will be needed anyway) and tools that support an 
automatic mapping between schemas.

PART B
1. Requirement: General / Terminology
2. Implementation Specification Section number: General
3. Criticality: Major
4. Comments/justifications for changes: The document submitted is not 
backwards compatible with GMLCOV. The changes in terminology 
(regular/rectified; irregular/referenceable) with the introduction of 
CIS 1.1 need to be clarified/harmonized.
