[OpenLayers-Dev] ESRI // WCS DescribeCoverage 1.1.0

[Christopher Eykamp]

Hello,

I am getting the attached response from an ArcGIS WCS server, with 
request DescribeCoverage and protocol version 1.1.0.  OpenLayers (latest 
1.x from GitHub) cannot retrieve the Title or Abstract attributes 
because the namespaces referenced in the 
OpenLayers.Format.WCSDescribeCoverage.v1_1_0 object conflict with what 
is referenced in the document.

Specifically, the OpenLayers namespaces object includes this line:

     ows: "http://www.opengis.net/ows/1.1"

This in turn is used to generate a namespaceAlias lookup, which will 
return "ows" when looking up "http://www.opengis.net/ows/1.1". However, 
in this case, I need "ows" to be mapped to 
"http://www.opengis.net/ows".  If I make that change in the namespaces 
definition, tests break.  Unfortunately, given the way the aliases are 
defined, I cannot add a second namespace that maps to "ows", which might 
fix my problem.

I am unsure how to proceed.  I can't tell if I am encountering a 
misbehaving server, or if this is just a limitation of the way 
OpenLayers is architected (hard-coded namespaces that can only have one 
namespace map to a given alias).  Or have I misunderstood something at a 
more fundamental level?

Thanks for your advice!

Chris
