[owslib-devel] wps branch available

Thu Nov 10 02:11:49 PST 2011

 Hi to all

The namespace "http://www.openspatial.net/wps" is an old namespace and
has been dropped (if you look at the WPS1.0.0 document you have it in
the SOAP example in page 69).

In the OGC world the schema structure takes precedence over
documentation, meaning if it is in the schema then is an "absolute
truth", and the WPS using that namespace should be updated.

Luca, maybe you should use an "open mind" approach, using what ever
namespace is assigned to wps. See the example below on how to get the
namespace:

import urllib, stringIO
from lxml import etree
xmlIO=urllib.read("http://schemas.opengis.net/wps/1.0.0/examples/53_wpsExecute_request_ComplexValue.xml")
wpsXML=etree.parse(xmlIO)
wpsXML.getroot().nsmap["wps"]
>>'http://www.opengis.net/wps/1.0.0'
