From Wikipedia, the free encyclopedia

Here is a list of rules and queries to check them

A line listed in the japan railway infobox should be a railway line

[edit]

Query to find Tokyo Metro (an operator) listed as a line

SELECT ?station ?page WHERE {
     ?station dbpedia2:line <http://dbpedia.org/resource/Tokyo_Metro> .
     ?station foaf:page ?page
}

This works but exposes some where two infoboxes are required.
