Agreed. It would be helpful to have a conversation on what the various
constituencies need (different from want) to see at their level. The
child, the parents/guardians, the teacher, the
principal/administrator, and educational bureaucracy. We should also
consider the needs of those of us who have to fundraise by showing
progress of ongoing effort.

True. Basic frequency counts such as frequency of use of activities,
usage by time of day, day of week, scope of collaboration are a few
simple one. Comparison of one metric vs the other will need more
thinking. That's where we should talk to the constituents.

If the visualization subsystem (underlying tech pieces) are common and
flexible, then we can start with a few basic templates, and make it
extensible, so we can all aggregate, collate, and correlate as needed.
I'll use an example that I'm familiar with. We looked at CouchDB for
two reasons: 1) It allows for sync over intermittent/on-off
connections to the Internet and 2) CouchDB has a "views" feature which
provides selective subsets of the data, and the "reduce" feature does
example Leotis had at the OLPC SF summit

A great start for a great year ahead!
