Thank you for the links. Note that the page about the selling options raises more questions than it answers (how common are the listed options?). While it is incidental that auction houses may also be equipped with a stockyard if they also hold livestock auctions, this is not a necessity for some of the options. Although, I acknowledge that the few USA livestock "market" POI I've checked in OSM were placed near barns by farm owners, so calling them "auction houses" seem a bit stretch.
It looks like we are going to be having separate tagging conventions for livestock auctions compared to livestock markets, as it would probably not be comfortable for mappers in the USA and Australia to add auction=yes to every livestock auctioning marketplace without presets. The working of a common market is different from an auction house. In the former, the seller bring a few of their own home produce, remains at their table all day long, waiting for potential customers and working with average prices. This method can work even in case of very low attendance, as unsold items could be brought to market on the next day as well. While auctioning of items can be a much quicker undertaking, especially for big producers having a large number of items for sale. From the viewpoint of a buyer, you can come to the marketplace at any time when it is open to purchase a given good, while you will need to attend an auction according to a fixed schedule if you want to get something, although at the end of the day, you may leave empty handed. I don't feel strongly about the exact tags we will use for this purpose, although putting livestock auctions below the general concept describing auction houses that can auction various things can have its advantages. For example: amenity=auction_house + auction=livestock;grain amenity=auction + auction=livestock;grain I'm not sure what other kind of merchandise you sell through auctions, the most common ones around here deal with vehicles, antiques, art, jewelry or real estate. Here's the alternative: amenity=livestock_auction The problem with this one is that I have a feeling that mappers would try to abuse it by typing livestock_market by choice or by accident, however that is a separate concept in other parts of the world. As hinted earlier, most towns around here hold frequent livestock markets ("állatpiac") at a fixed place similar to how common markets ("piac") are being held on certain days. For smaller communities and less common livestock, livestock trade shows (fairs, "állatbörze"/"állatvásár") are being organized in various regions, sometimes on areas dedicated for this purpose, while at other places on common grounds. On both of these, haggling is the common purchase method, not auctioning. According to our tax office, we also have a legal category for livestock auctions ("állatárverés"), although they seem to be rarely held. This is how a livestock market/fair looks like: https://www.programturizmus.hu/ajanlat-dunafoldvari-orszagos-allat-es-kirakodovasar.html https://www.szoljon.hu/cimke/allatvasar/ Here's how common they are, although many do not possess online presence: https://www.programturizmus.hu/ajanlat-allatvasar.html http://www.vasarokfesztivalok.eoldal.hu/cikkek/orszagos-vasarok--a---k-/ According to Wikipedia and personal experience, It is customary to classify marketplaces by function: marketplace=livestock/antique/farmers/fish/flea/flower/craft I feel that farmers' market, fish market and crafts market are related and may perhaps be combined into a single category of "producers' market", but do share what you think about this. This term is mostly used in connection with farmer's (and artisanal handicraft) markets in Hungary, as fish markets are rare, but we have a lot from every other category.
