How many versions of De Lijn have you applied? If you rely on the existence of the ref= tag in an OSM bus stop to tell that the 2014-04 version of the import has been applied to it, then you will have a problem to tell the same way if a 2015-xx version is applied. source=TEC 2014-04 is required unless you are prepared to change your algorithm with every new update. > I know that you know how to bulk add source tags, the explanation was > only there for when you were going to insisit on adding them yourself. > You can, if you want, but I'm not going to.
