Ah, I grepped for too much of the value.
Good to see *some* connection from source to sink.
Now, to help clean that up...

I think “Satellite” would be worthy of its own class.
I’d tuck it under the appropriate DBPedia superclass, but can I also tuck it
under the external class pext:ArtificialSatellite?

I’m logged into http://mappings.dbpedia.org/index.php/OntologyProperty:CosparId
but don’t appear to have edit permissions.
DO I NEED MORE PERMISSIONS?

I installed the extension, but
http://mappings.dbpedia.org/server/statistics/en/?show=100000 doesn’t show the
"Infobox spaceflight", which is the one that is used in
http://en.wikipedia.org/wiki/GOES_7. Any idea why it’s missing from the list?

(I can’t edit, DO I NEED MORE PERMISSIONS?)
What’s the difference between the info box mapping page ^^ and
http://mappings.dbpedia.org/index.php/OntologyProperty:CosparId ?
And, why doesn’t http://dbpedia.org/ontology/cosparld resolve or point to
either of these utility pages?
Would be helpful to get to the control pages from the data itself (so we can
reduce traffic on this list :-)
Regards,
Tim
