Some locations in Buenos Aires, Argentina are used for social dancing of tango (dance:style=tango). They usually have names and I understand how to map them.
Dancing events (“milongas”) are regular events on these locations - for example a week or once a month. There could be a milonga happening every Monday by one organizer and another one happening every Tuesday by a different one. Usually each of these events come up by different names to differentiate themselves. These event names are sometimes known by people better than the event location itself.
Example of a location - El Beso Club where Cachirulo milonga happens every Tuesday 9:00 PM - 3:00 AM and Perfume de Mujer every Wednesday 2:00 PM to 8:00 PM.
I would like to ask how to tag these event names. Use them in alt_name? Is it desirable to do so?
Is it possible to indicate opening hours per each of these even name or just add all of them to the node itself?
I suspect that there is no suitable tagging for this at the moment. At best add a mention in description.
But in my opinion, there are some other places in general where something happens on a regular basis that should not be mapped.
my 2 cents: OpenStreetMap is a geo database and is not intended to reflect the film program in a cinema, the fitness classes in a gym, the swimming training in an indoor swimming pool or the dance classes in a dance school.
I don’t think even a weekly market or a Christmas market is a correct reason to add this on the map.
Weekly markets modify the street with extreme regularity, affecting accessibility, parking and routing through certain streets for example. While milongas also may be quite regular, they only affect the amenity in question. If we tag milongas, we would also have to tag for example, named parties at clubs that happen every second Friday, or ladies nights, or theatrical performances that are long running, or any number of things. I’m not entirely opposed, it just opens a big can of worms that would probably need its own tagging scheme altogether.
