How about shop=butcher;alcohol ? Additional info (the fact it sells fish, beer/wine specifically) should be put in additional tags. Regarding search - ideally, I think the user should be able to say that they want "to eat a t-bone steak in mood lighting for under $20 less than 30min drive away", and any suitable restaurant would be returned - regardless of whether it be classified overall as e.g. "American" or "Steak/Grill". > That said, having a map where all stores are on it and mappers pick the > best and we get on with things gets us 95% of the value - but I wanted > to mention the semantics problem. Yeah...I think at this stage, it's useful to input as much detail as possible, even if you have to make up tags along the way, provided their meaning is explicit and self-explanatory. They must be self-explanatory to facilitate a possible future move to a more coordinated scheme, to get that last 5% of value without having to re-survey (highway=footway/cycleway/path should serve as a warning against non-explicit tag names!). _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
