Hi Peter,

thanks for the response. But, my question rises many more  
representation/reasoning issues, some cover issues of your previous  
email. More generally, to do it automatically

1. the query has to be represented in some formal user local language
2. a user local system (agent?) should be able to identify a subset  
of relevant resources (web services?) to which to submit the query  
(this is called automated  resource selection in IR - Information  
Retrieval)
3. Then, the local query has to be reformulated (using ontology  
alignment mappings) for each identified resource and submitted
4. each resource provides back a ranked list, which then has to be  
merged (this is called rank aggregation + data fusion in the literature)
5. (optional) the data has then to be translated back into the user's  
local vocabulary (again, using ontology alignment mappings)

I know and that's an option, but see also the DLMedia system ....
