This tag would be useful to map different types of non-profit workshops.
Electronic open workshops like fablabs  and hackerspaces. There are about 500 electronic workshops worldwide (either hackerspaces or fablabs)
It could also point to various forms or workshops : private, public, non-profit, informal, association, etc. so long as they are non-profit.
Automobile repair workshops should be tagged shop=car_repair, bakery workshop shop=bakery, and more generally any commercial workshop should be tagged with the key "shop" and not "workshop".
The tag would define the type of workshop in question, like workshop=fablab or workshop=hackerspace.
If a workshop has several uses, workshop=*, fablab=yes, hackerspace=yes could be used to tag it.
Nodes, particularly buildings.
Here is a proposition :
I proposed a more targeted approach to tag the fablabs via the amenity category, and the tag amenity=fablab (see Tag:amenity=fab_lab), but I believe this approach to be more pertinent and more useful.

Because some workshops don't fit well into those categories, and in particular even if hackerspaces may (I'm not so sure myself) be considered as "leisure" because they are community-oriented (goal is social collaboration), it is not the case with fab labs. Those are different since they're machine-oriented (the goal is the fabrication). "Repair", "shop" and "industrial" do not fit at all, amenity would but hasn't it been overused ? (I'm told) And as for "craft" it would be close, but I'm not sure electronics and robotics crafts would be comparable to shoemaker, carpenter, locksmith or other similar crafts (wouldn't know how to explain it better in english though).

I understand fine and like amenity=workshop with workshop=fablab
