Today on the Linking Open Data mailing list, Kingsley Idehen of OpenLink Software announced that he is preparing to load the entire LOD cloud into Virtuoso 6.0 Cluster Edition. The datasets are being added to a table on the ESW wiki, making it convenient for anyone doing Semantic Web research to get a hold of the datasets. Once all the datasets are added we should have a better idea of how much linked data there really is out there. This may also raise the bar for other triple stores and force them to develop methods for storing several billion triples.

Here are his instructions for adding your dataset to the table:

• Go to: http://esw.w3.org/topic/DataSetRDFDumps
• Add your data set to the table (if it isn't already listed) or correct erroneous entries
• Add a URL entry to the "Archive URL" column
• Add a Publisher URI to the "Publisher / Maintainer" column (used for the construction of Attribution Triples)

If you don't have a URI for yourself, you can get one by registering and you will receive one.
