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.
That was a point in time.
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.
We have 30 RDfizers written at different points in time.
If an RDFizer is imperfect (like most of LOD) simple feedback will do. I
don't even remember the last time I looked the RDFizer for Yahoo Finance.
Okay, one bad and very very old cartridge, 29 to go :-)
Did you improve the quality of the external links in the meantime and do the
cartridges regularly deliver data?
If OpenLink has one attribute, I don't think "static" would be the one
:-) These cartridges changes on a daily basis depending on a myriad of
circumstances (including feedback).
As with all things, feedback would be very helpful.
Another problem is that many of the sources are not really Open Data as
various license restrictions apply.
The ones that concern you re. open data to should be relayed to me, at
the very least we don't want to be violating anyones publishing rules etc..
Kingsley
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.
