[ZOO-Discuss] any interest in a wps bakeoff?

Sun Jan 30 17:33:17 PST 2011

Not quite sure what is being suggested; the workshop sounds positive and all - but we are children of the internet age; and if we are going to collaborate across projects we will do better to set up on the internet and gather interested parties.

Meeting in a single location; especially one on the other side of the world; put me out of the picture for example.

I mean if each projects are well informed that this will occurs and are asked to contribute back to the effort. I also think this can a great help for each WPS projects that can get benefit if feedbacks are well returned back to each projects individually. Maybe some bugs can be found this way.

Unfortunately I'm unsure of the status for deegree and GeoServer WPS implementations as I didn't see mention of them in the WPS-GRASS-Bridge [1] made by Soeren Gebbert (in fact, strangely checking twice when writting this email I noticed that 52°n disappear, maybe the code moved somewhere else). Maybe it can really useful in the effort of comparing solutions as those three are providing same services based on the same libraries back-end.

I think it is a key point, indeed I think it is great to compare existing services and how they work / run but I think it can be also great to compare time required to develop and deploy new services. This can be a hard and long task to organize such a comparison. Indeed I think that somebody out of the ZOO-Project community should be involved to provide information on how to develop and deploy new services to get "real" feedbacks.
>> 
>> I also think that comparison between project should also imply full testing of WPS capabilities. I mean, does each projects support WSDL/SOAP or not (I know that ZOO-Project is not supporting yet but will really soon ! :D ), can we well use both GET and POST request from XML request sent to the server (using Header and Body or BodyReference if my memory is correct). Maybe some XML validation can be done also about the answer returned back to the client.
