Thanks, I looked into this extension but I cannot see how it solves one of my
problems. Here is an example:

Here some data:

{{#set_internal:Part of model | Has qty=1 | Has id=3003    | Has color=green }}
{{#set_internal:Part of model | Has qty=1 | Has id=3660    | Has color=green }}

And a query:

{{#ask:[[Part of model::+]][[Has color::green]]
|mainlabel=-
|? Part of model
|? Has qty
}}

Then the resulting table will list both parts like this:

Part of model | Has qty
--------------+--------
4017-1        | 1
4017-1        | 1

But I want the sum of all green parts in a model:

Part of model | Has qty
--------------+--------
4017-1        | 2

Is there a way in semantic mediawiki to aggregate or group tabular results like
this?

cheers, josch
