GML/XML is *not* the issue, you know that: It's almost any application outside OSM database. It's about reusability and consistency!
I love the approach of key-value pairs (and I like beers too... ;->). I agree with Martijn that before all, spaces must be kept out. I agree too with Frederik: Colons can be included as namespace delimiters. Namespace, tags and keys reminds us, that OSM is a database and *not* a Wiki on an island (whereas I'm loving Wikis used as they are)! So I'm sorry, guys, but I have to insist: I propose distinctly to restrict key names (elemement, tag) to the set 'aAbBcCdDeEfFgGhHiIjJkKlLmMnNoOpPqQrRsStTuUvVwWxXyYzZ_', now plus colon as namespace delimiter, allowed once and not at the beginning or the end. -- Stefan BTW: Restrincting tags in del.icio.us to ASCII did not restrain the success of social bookmarking in any way IMHO. 2008/2/12, Andy Robinson (blackadder) <[EMAIL PROTECTED]>: > > Stefan Keller wrote: > >Sent: 12 February 2008 12:36 AM > >To: [email protected] > >Subject: [OSM-dev] Restrict key names on order to retain reusability of > OSM > > > >Hi all, > > > >I just have finished a converter of OSM xml format to GML and I BOLDLY > >suggest to constrain the allowed characters of tags (= key-names) to the > >following XML related set: > >'aAbBcCdDeEfFgGhHiIjJkKlLmMnNoOpPqQrRsStTuUvVwWxXyYzZ_' in order to > retain > >reusability. > > No chance, GML is going to have to get with the times.
