Hi Kingsley,

The last time I checked the cartridges, I had the impression that they were
not very much interlinked with the rest of the LOD cloud and about half of
them were down.

The links to DBpedia were rather strange. For instance the first link I
found owl:sameAs'ed Yahoo finance balance sheet with Dbpedia bed sheet,
which is even for me as a big supporter of owl:sameAs links a bit too much
Semantic gap.

Did you improve the quality of the external links in the meantime and do the
cartridges regularly deliver data?

Another problem is that many of the sources are not really Open Data as
various license restrictions apply.

Cheers

Chris

Anja,

You have MySpace and Flickr Wrappers but still don't include all the 
Virtuoso Sponger Cartridges (which are wrappers) to the Cloud [1] ?

Also, the LODD data sets page should be linked to: 
http://esw.w3.org/topic/DataSetRDFDumps, so we can track down the dumps 
with ease re. the Virtuoso LOD hosting instance.
