As with WFS, WMS, or WPS, vendors have the option of extending WCS capabilities with custom parameters. This way some extra functions can be delivered to users to help them manage their coverages.
In the case of WCS, GeoServer offers a basic customization; you can use a vendor parameter to filter out results according to a namespace.
Create a request for the WCS capabilities with cURL:
$ curl -u admin:geoserver -XGET -H 'Accept: text/xml' -G http://localhost:8080/geoserver/wcs \ -d service=WCS \ -d version=1.0.0 \ -d request=GetCapabilities \ -d namespace=NaturalEarth \ -o coverages.xml
Now open the file that stores the results and check that only the coverages from the
NaturalEarth
namespace are listed:… <wcs:CoverageSummary> <ows:Title>blueMarble</ows:Title> <ows:Abstract>Generated from GeoTIFF</ows:Abstract> <ows:Keywords> <ows:Keyword>WCS</ows:Keyword> <ows:Keyword...
