Hi all,
we are in the process of drawing the next version of the LOD cloud
diagram. This time it is likely to contain around 180 datasets
altogether having a size of around 20 billion RDF triples.
For drawing the next version of the LOD cloud, we have started to
collect meta-information about the datasets to be included on CKAN, a
registry of open data and content packages provided by the Open
Knowledge Foundation.
The list of datasets about which we have already collected information
is be found here:
http://www4.wiwiss.fu-berlin.de/lodcloud/
In addition to basic meta-information about a dataset such as its size
and the number of links pointing at other datasets, we also collect
additional meta-information about the license of the dataset,
alternative access options like SPARQL endpoints or dataset dumps, and
whether there exist a voiD description of the dataset or a Semantic Web
Sitemap.
So if your dataset is not listed yet and you want to have it included
into the next version of the LOD cloud, please add it to CKAN until next
Wednesday (September 8th, 2010).
Also, if we have collected wrong information about your dataset or if
your dataset is only partially described up till now, it would be great
if you could add the missing information.
Guidelines about how to add datasets to CKAN as well as about the tags
that we are using to annotate the datasets are found here:

We thank all contributors in advance for their input and help, which
hopefully will allow us to draw the next version of the LOD cloud as
accurate as possible.
Cheers,
Anja Jentzsch, Richard Cyganiak, Chris Bizer
