hello @species
I think we also be aware to distinguish between initiatives and places.
eg. spektral in Graz is a place.
http://spektral.at/
the volxküche there is an initiative.
http://spektral.at/projekte-gruppen/
I think that Initiatives are much more volatile.
Many can be in one place, at one adress.
They easily start and end, or start being inactive.
… and I am not even sure, if it ok to put them on OSM?
I just noticed that difference here at food not bombs website, as I searched for the austrian chapters, and vienna website does not work, graz website had it´s last activities 2004.
