The first question needs to be "What are you trying to solve?". Yes it
might be nice to have that information but in the end it should be there
for a reason.

I can see the purpose of finding broken clients/apis but i guess this
information is obsolete after 14 days (3 hours at the commit rate in the
client svn).

So you'd want client version, and data source (API, ROMA, XAPI) and
better put the url in there or some generator name from the osm file as
i'd guess we'll see ROMAs grow like mushrooms.

For finding clients a metadata xml file uploaded parallel to the tileset
and deleted after some time would be sufficient. No need to keep that
data forever ...
