data

Peering into Journal data

Our pilot sites in Jamaica run on the OLPC XS School Server. The XS provides backup services for all the different XO laptops registered to itself. The backup stores the Journal of each laptop. For those who are unfamiliar with the Journal, it is an application that acts as a filing system, except that it does not use the metaphor of files and folders.

When data tell stories

We finally got past a major hurdle of pulling metadata from the journals of the XOs at the two schools. The XS School Server collects journals of all the XO laptops and keeps the aggregate stored, in case we need to recover lost work, or push a child's work back into a newly-reflashed laptop.
