So roughly speaking the query for the Documents section should be all subtypes of nfo:Document but NOT nfo:Presentation Currently this is simply not possible in Zeitgeist, because we do logical OR between all subject templates.

The deal is that the designers think that the Documents section should not contain Presentations (which makes quite good sense if there is a separate section for this). Also we'd like to have an "Other" section with unclassified stuff. But since nfo:Presentation is a subclass of nfo:Document a query for all documents would also include all presentations (which is "correct", but not what we want in this particular case). So roughly speaking the query for the Documents section should be all subtypes of nfo:Document but NOT nfo:Presentation Currently this is simply not possible in Zeitgeist, because we do logical OR between all subject templates. What I'd propose to do to make these kind of queries possible, is to switch to logical AND between subjects, but keep it at logical OR between events. So in code I'd like the following code to work: su1 = Subject.new_for_values(interpretation=DOCUMENT) su2 = Subject.new_for_values(interpretation="!"+PRESENTATION) ev = Event() ev.subjects.append(su1) ev.subjects.append(su2) # now query for [ev]. As you probably realize we have the same problem (but even stronger) in the "Other" section where we want to exclude all the listed sections and match everything else. ___ Mailing list: https://launchpad.net/~zeitgeist Post to : zeitgeist@lists.launchpad.net Unsubscribe : https://launchpad.net/~zeitgeist More help : https://help.launchpad.net/ListHelp
