WCS 1.1.1 GetCapabilities request does not support the sections

[nsavard]

"sections" parameter is not supported for a WCS 1.1.1 GetCapabilities request. This makes the capabilities response to not validate and the OGC test failed.

The request is: ​http://dev1.lan.mapgears.com/manwe/cgi-bin/mswcs111_ogc_cite?service=WCS&request=GetCapabilities&sections=OperationsMetadata,Contents

The OGC CITE test engine is: ​http://cite.opengeospatial.org/te2/

If desired, I would be willing to implement this feature. It clearly is something I should have done the first time around. Let me know.

comment:1 Frank, waiting for Tom to comment.

[tomkralidis]

Thanks Frank. I'll check your changes once committed.

I have implemented support in trunk for SECTIONS (r9291) and some testing in the autotest suite (r9291).

The support is case sensitive for the argument to Sections in the URL - should it be? If testing goes well in trunk, an I can back port this if it is deemed appropriate.

BTW, I get a lot of failures in the msautotest/wcs tests - alot related to filtering. Should the following be sufficient?

Nice! This works as expected. All results are valid XML (checked with XML Spy 2009).

Should be case-sensitive (i.e. Contents instead of CONTENTS).

What happens if the section value passed is an invalid one (i.e. sections=foo, or even sections=ServiceProvider,foo)? OWS 1.1 says (document 06-121r3 ​http://portal.opengeospatial.org/files/?artifact_id=20040), from Table 3:

Names	Definition	Data type and value	Multiplicity and use
sections Sections	Unordered list of zero or more names of requested sections in complete service metadata document	Sequence of Character String type, each not empty. Value is list of section names. Allowed section names are specified by each Implementation Specification	Zero or one (optional). When omitted or not supported by server, return complete service metadata

Norm: can you run the new build through the CITE test and see what gives?

RE comment:5

I noticed this also on Ubuntu Intrepid. Your switches are correct.

Tom and I noticed that these two tests failed a long time ago: test wcs_getcov_gdpng8_11.dat test wcs_getcov_grd_11_wgs84.dat

New:There have been a small changes in the following tests (checked in OpenEv): test wcs_16_repro.tif test wcs_16_ds.tif test wcs_16.tif

New: I cannot open these two images in OpenEv but when I do the GetCoverage request in the browser I can see the generated image. Don't know why. test wcs_bilinear.png test wcs_simple.png

Yes Tom I'll do it.

[nsavard]

RE comment:6

GetCapabilities section parameter works but the OGC CITE test failed with the error message as shown in the ticket description. It seems that the "Capabilities" tag is not expected.

[warmerdam]

Are we missing some sort of name space prefix for the Capabilities tag or something? I get quite lost in these aspects of XML. Tom? thoughts?

The namespace prefix is not needed in this case, since the default namespace is xmlns="​http://www.opengis.net/wcs/1.1".

Having said this, GeoServer seems to do the same thing:

​http://sigma.openplans.org/geoserver/ows?service=WCS&request=GetCapabilities&version=1.1.1&sections=OperationsMetadata,Contents

So I'm not sure what's up. Norm: can we get more details on the failed assertion? Or query the CITE folks?

One other thing we'll want to check is whether we should throw an exception if an unknown WCS section name is passed, i.e.:

​http://sigma.openplans.org/geoserver/ows?service=WCS&request=GetCapabilities&version=1.1.1&sections=OperationsMetadata,Contents,Foo

[nsavard]

Tom: I'll post a question to them.

[nsavard]

Tom: Before I sent an email I validated the capabilities response and found that there is a problem. Could you check ticket 3118 (​http://trac.osgeo.org/mapserver/ticket/3118)?

[nsavard]

I posted a question to the forum and I'm waiting for their answer.

[tomkralidis]

Norm: I wonder if you ran this test again pointing to the right schema (per #3118) if you get different results?

[nsavard]

Tom: I'm pointing to the valid schema. Am I? See my Web object below.

That's fine. Make sure you have the latest set of schemas (​http://schemas.opengis.net/SCHEMAS_OPENGIS_NET.zip). Or, if you comment out ows_schemas_location, the code will default the value to ​http://schemas.opengis.net/

[tomkralidis]

FYI I believe this may be related on #3086.

[warmerdam]

As I understand it, the only remaining issue is related to whether the cite test recognises the Capabilities in the returned document and this seems to be related to using the correct schemas.

This does not seem closely related to the original topic of this ticket. If schema problem persists and is not covered elsewhere, perhaps you could create a new ticket for the issue Normand?
