Confusion between CITE tests, specification and schemas published online

[aaime]

Some extensions declare different namespaces in the PDF specification (followed by CITE tests) and in the published schemas.

For example, interpolation:

• In the specification, page 1 (these are not XML namespaces, but it's easy to confuse them):

This document establishes the following requirements and conformance classes:
interpolation, of URI http://www.opengis.net/spec/WCS_service-extension_ interpolation/1.0/req/interpolation; the corresponding conformance class is interpolation,
with URI http://www.opengis.net/spec/WCS_serviceextension_interpolation/1.0/conf/interpolation

• In the specification, page 3, Table 2, the "int" prefix is bound to http://www.opengis.net/wcs/interpolation/1.0

• https://schemas.opengis.net/wcs/interpolation/1.0/wcsInt.xsd declares
  xmlns:int="http://www.opengis.net/WCS_service-extension_interpolation/1.0

• https://schemas.opengis.net/wcs/interpolation/1.1/wcsInt.xsd declares:
  xmlns:int="http://www.opengis.net/WCS_service-extension_interpolation/1.1

• The test for interpolation in this repository declares xmlns:int="http://www.opengis.net/wcs/interpolation/1.0".

I'm going to guess the schemas at schemas.opengis.org are wrong... could you confirm?

Thank you for reporting.

I also come to the conclusion that the namespace used in the schemas at schemas.opengis.org are wrong.
However, this question should be answered the SWG (CC @pebau). Thus, I propose to contact the SWG directly.

indeed, quite confusing - not only for you. By way of history, when these specs were written coverages happened to be the first users of a ModSpec in beta (at best) - see how ModSpec discussion is still going on today.

I always had asked for a recipe "OGC URLs for dummies", so suitable for me. We should look at that as the ground truth for inspection, verification, and - should it be necessary - fixing.

@dstenger, @ghobona : can you point us to the authoritative OGC URL reference? Based on that, I am available for getting hands URL-dirty.
