select ?g ?mg where { ?g a nrl:InstanceBase . OPTIONAL { ?mg nrl:CoreGraphMetadataFor ?g . graph ?g { ?r ?p ?o. } } FILTER(!bound(?r) || !bound(?p) || !bound(?o)) . } LIMIT 100
This seems to be faster, but just by around 10-20 milliseconds. It's difficult to determine which query is faster.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The new GraphMaintainer is created at startup and will slowly remove empty graphs which are left over from the pre-DMS days. It uses a delay between each removal operation to not impose on the user's work at all. Thus, it takes forever to remove the graphs but that is no big deal.</pre>
