Another thing to remember is that the relation analyzer and relation browsers don't support super-relations *yet*. My gut feeling is that if we start using super-relations in a consistent manner, it's more likely that the analyzer (and hopefully the API) will begin supporting them consistantly. In the long run, using super-relations to create relation hierarchy would allow us to separate physical attributes of a way (or node) from the logical attributes of a route. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

what is wrong with 2 relations? I didn't say 2 are needed but why do you think 2 is bad?

It is not possible to get the history from the server Sorry, the data for the relation with the id 94043, took too long to retrieve. any split of any road segment for a bridge, speed limit change … requires a new version and increases the number of members. do you still think a potential inconsistency has any relevance compared to this? ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Apart from the obvious you aren't uploading/download every single object referenced by the relation every time you edit it, and the references to objects in the relation should still be reasonbly small so I don't see what the fuss is all about. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Then why didn't you report a bug so less information is attempted to be returned? You still have the problem, breaking it up into 2 relations didn't fix it, and as time passes even more changes will occur, the number of objects isn't the main problem. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
