Hello,

Having just seen the bigger and better LOD cloud [1]. I was wondering whether QDOS should have a link to DBpedia, as we emit owl:sameAs relationships from celebs to dbpedia resources: see Barak Obama's turtle file [2]. QDOS currently has around 100,000 people, about half of which are linked to dbpedia resources.

Cheers,

Mischa

Hi Kingsley,

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

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

Hi all,

we are currently updating the LOD cloud. Find the draft here:
http://www4.wiwiss.fu-berlin.de/bizer/pub/lod-datasets_2009-02-27.png

We have already added:

1. the RKBExplorer cloud
2. the Bio2RDF cloud
3. the LODD cloud
4. GeoSpecies
5. LIBRIS

Statistics on triple and link count (as well as target sources) are
missing for the following sources:
- Faviki
- RDFohloh
- OpenCalais
- LIBRIS

Did we forget any new data sources or links between data sources?

Keep in mind: A data source qualifies for the cloud, if the data is
available via dereferencable URIs and if the data source is
interlinked with at least one other source (meaning it references URIs
within the namespace of the other source).

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.
