Something that is driving me a bit bonkers, is which taxonomy do you use for something that is primarily B2B (business-to-business). Is it /craft/ or is it /shop/ ?
A few examples …
A personal acquaintance has a business that specializes in rebuilding automotive (and truck presumably) superchargers. This is very specialized, and I know it. Even if I can’t find a previous tag or keyword, where is the logical place to put it ? I’m reasonably sure that 99% plus of his business is done via freight packages, so he has no store-front to speak of. It really doesn’t feel like a shop to me. Having said that …
There are various businesses in my area that deal with agricultural machinery. Mostly for farm activities, but we do quite a bit of forestry & logging here, and there are those flavor of dealers also. Searching tag values under /shop/ for /machine/ yields a number of likely variants in use. This takes me back full circle that /shop/ is not necessarily for B2C (business-to-consumer), or perhaps it has been misused a bit.
I also tried to find something to represent a business that primarily rents power tools (everything from a hand drill up to self-powered lifts). There are several of these I can think of, but no obvious tag value. IIRC, I was creative and went with /shop=tool_rental/. Maybe this is more common around here, but I think these type of businesses exist in many areas. While this business does mostly B2B, I’m sure there is B2C walk-in as well.
There is another business that builds boats. Not so much the classic wooden boat type of facility, but they build plenty of pontoon boats, houseboats, floating docks, and specialty items. I have tagged them as /craft=boatbuilder/. I’m not sure if what they do is really so much a craft, as boat engineering and assembly. Mostly they use aluminum for the hulls.
OK, rant off.
