Labelz are small self-adhesive labels one can put on things that are somewhere in publicly used enviroments like hackerspaces, offices, workshops and so on. The label should make it possible to understand who owns this thing, what you are allowed to do with it, what to do if it is broken, if you can move it someplace else, and things like that.
For information about earlier versions of Labelz, please look into the history of this Wiki article.
