Markus, I believe this kind of pings should be happening upon update, not on a nightly basis. Can you incorporate it into saving process?
I did not see many people who did ping the semantic web yet (email below).
In short, just run the maintenance script SMW_pingSemWeb.php:php SMW_pingSemWeb.php -h http://ontoworld.org -t ptsw,sindwith "http://ontoworld.org" being your server basename (no path).
Doing this would help us to get a better lower estimate about how much
SMW-based semantic data is out there, and we would really appreciate that.
Again, note that this does not expose any data that is not public yet anyway.
Thank you for supporting the project,
P.S. You can find the results at
http://pingthesemanticweb.com/stats/namespaces.php (your wiki should rise up
there instantly :-)
