Yes, but that's the easy and not too important part.
I think splitting a route relation could work as follows:
1/ Download all ways that are members of the relation:
wget 'http://www.informationfreeway.org/api/0.5/relation[name=Frankenweg]' \
2/ Open frankenweg.osm in josm.
3/ Mark the northern part of the route and cut it.
4/ Save the rest as frankenweg-s.osm (for south part).
5/ Empty the josm window.
6/ Paste the cut northern part (see 3/).
7/ Create the new route relation "Frankenweg-Nord" and make all ways
member of this new relation.
*** Now I'd like to upload this relation. Does this work?
8/ Empty the josm window. Load frankenweg-s.osm and create the other
relation, say "Frankenweg-Süd", etc. pp.
9/ Remove all members from the old "Frankenweg" relation.
*** How can I accomplish this?
10/ Make "Frankenweg-Nord" and "Frankenweg-Süd" members of the old
*** Which tags should you use?
11/ Add a note to the old "Frankenweg" relation explaining that this is
a 'relation collection' metarelation, etc. pp.
