I already tried the first one before, but it takes some time to run (hence the question). Finally, it outputs 68639869, which is 73% of total Geonames triple count. On second invocation (after waiting 20 minutes), the same number is returned. But since the query is fast on second invocation, the result might be taken from cache. Kind regards, Jens -- Dipl. Inf.
