Internet access in the developing world is often expensive and unreliable. CTED has created a system that puts portions of the internet on portable hard drives for school children to be able to access web pages on any topic in the form of an offline – searchable information portal.

This Contextual Information Portal (CIP) is an offline repository of web pages tailored to the particular context in which it is to be used. A CIP is intended to be paired with some server software (e.g. RuralCafe) and a user interface (e.g. a web browser) so that users can reliably interact with large amounts of context appropriate web content while being completely offline or behind a slow/intermittent connection. We have designed and implemented a CIP Generator for easily construction such portals.
