Re: Data format

Hi,

The content inside the WARC is encoded in N-Triples, see the sample code
(added to the files of the Yahoo! Group, see [1]) on how to extract it.

Once you have the N-Triples you can as you say process them using any
library. The sample code shows how to count the triples using Sesame.

Best,
Peter

Hi Jans, The plan is to have the entire dataset available for download in the WARC format as a set of files. (Some users may have limitations storing files...
