[Foundation-l] UvA what they need in log data from the Wikimedia Foundation

[GerardM]

Hoi,
It is the distribution in time of geographical needs that is critical. When
a particular article becomes relevant in a certain area, you want to address
the flood of requests by distributing the article to the peers that are
close to where the demand is. In this peering system, a node may have an
article but it is not necessary to have all articles.

As was mentioned before, work has been done on the data received from the
WMF. Based on the data a paper will be published in the near future. When it
is available, I will post a link.
Thanks,
    Gerard
