You're over-thinking this, Nathan. Think about it from a mapper's perspective. start_date should be the date it first became a railway. end_date should be the date it ceased to be a railway (that is, the tracks were removed). And you don't need start_date:railway, because you've already created a relation for most every railway, so put start_date on the relation. -- --my blog is at http://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
