Hi, Are the joins and processing such that you could handle them by preparing a database view to be used as data source? In the future also SQL queries will be supported. You are talking about GetFeatureInfo, which is a WMS request, and WFS. Which one are you going to use? One difference in their behaviour is that Geoserver sends allways all the attributes with GetFeatureInfo but with WFS the list of attributes can be given in the request. It is not allways possible to make a view that is optimal for GetFeatureInfo because some attributes may be necessary for rendering and styling and therefore they must be included in the view even if they are unnecessary for GetFeatureInfo.

It is a pain to set up- no GUI - and there are some minor issues that the documentation doesn't quite prepare you for, but it is quite powerful. There are a couple of us now on the list working our way through the tutorial, flushing out bugs and having visions of app-schema GUIs dancing in our heads, so you won't be alone. See http://docs.geoserver.org/stable/en/user/data/app-schema/index.html Tara Alessandro Ferrucci wrote: Hello, I am interested in writing a WFS-like service which will do a bit more than pull from 1 postGIS database... I would like to do some application-level joins and possible processing/massaging of the data before it goes back to the client. would I need to define a custom OWS service in my geoserver instance? Can I still make this service look like a WFS call assuming that I format it in a format adhering to the WFS spec?
