[Freegis-list] geospatial web services help requested

[Markus Müller]

Hi Christoper,

I pick questions nr. 4) ;-)

The OGC started developing Web Services ( OGC Webservers = OWS) a while 
before the now "mainstream" Web Services standards such as SOAP and WSDL 
existed. There most OWS are non-soap, but either KVP (Keyword Value Pair 
encoding = CGI style) or XML encoded. During the last years the 
discussion about usage of SOAP and corresponding standards took place at 
almost all meetings of OGC and there was no general answer found if 
using SOAP makes sense or is a necessity for OWS. So there is now a slow 
transition towards these standards, the newer OWS specification such as 
Catalog Serivce now include a SOAP binding, so it is possible to 
implement them with or wittout SOAP. Similar bindings will be developed 
during the next months and years for most/all OWS.

Hope this is the answer you are looking for.


regards

Markus
