I have been hearing about SchoolTool more often, lately.
They have a big vision: “a common information systems platform for school administration from California to Calcutta, via Cape Town! We hope to provide a single tool that will be readily adapted to the specific regulatory requirements and practices of different countries and regions, but that retains enough common functionality to make a shared development effort worthwhile.”
This makes sense to me as an ideal application for an Open Source approach. SchoolTool (like GroupServer) uses Zope and Python. It has a standards-based calendar module called SchoolBell.
Is anyone using SchoolTool in Aotearoa/NZ?
