[tdwg-tag] WPS for Names

Dear Kevin,

During the last year I was involved in a project which used some of the OGC
SWE (sensor web enablement) standards. Based on this experience I would say
using OGC standards is not an easy thing at all.
The main reason is that OGC specifications generally are quite 'generic' and
require to specify what they call application profiles which require
considerable efforts. What I found worst with OGC standards was that they
perfectly enable you to XML describe any thinkable metadata but when it
comes for example to deliver DATA via O&M you are left alone and you can
indeed deliver anything you would like to as long it fits in a result
element of type "any". As a result clients will perfectly be able to parse
requests and metadata but probably fail to handle the 'real' output, (the
data) when it come from outside your community even if the same 'standard'
is used.

>>>From what I have seen in the WPS specification this is also true for this
standard. You can nicely encode your requests etc but when it comes to
deliver the output of such a service the specs say:

10.3.1 Execute response parameters
The form of the response to an Execute operation request depends on the
value of the ResponseForm parameter in the execute request. In the most
primitive case, [...] RawDataOutput

So it seems that also WPS focuses on metadata and you would have to specify
(standardise ;) !!) the output format yourself.

best regards,
