Hey Tony,
I would like to use this list until such time that WAD kicks us off. Our
testing will be very useful to others involved in pilots.
Notes on the Library Server: The library server is for Nepali stuff that
isn't currently in digital form. We are working w/ publishers and
authors to get children's literature digitized and put on an Internet
accessible library. This will be an ongoing process. The library may
scale to a very large size so for now we are planning to have a
centralized server and use aggressive caching on the school server.
Localization: Our development team http://www.olenepal.org/team.html is
working w/ teachers to develop localized English and math activities. We
would like to localize Moodle as well but that is out of scope for what
we can accomplish in the next 2 months.
The library interface is already localized but I am using the English
page because I can't read Nepali very well.
We could really use your ideas on redundancy. that would be very helpful
