document: Dtwiki : a disconnection and intermittency tolerant wiki Wikis have proven to be a valuable tool for collaboration and content generation on the web . Simple semantics and ease-of-use make wiki systems well suited for meeting many emerging region needs in the areas of education , collaboration and local content generation . Despite their usefulness , current wiki software does not work well in the network environments found in emerging regions . For example , it is common to have long-lasting network partitions due to cost , power and poor connectivity . Network partitions make a traditional centralized wiki architecture unusable due to the unavailability of the central server . Existing solutions towards addressing connectivity problems include web-caching proxies and snapshot distribution . While proxies and snapshots allow wiki data to be read while disconnected , they prevent users from contributing updates back to the wiki . In this paper we detail the design and implementation of DTWiki , a wiki system which explicitly addresses the problem of operating a wiki system in an intermittent environment . The DTWiki system is able to cope with long-lasting partitions and bad connectivity while providing the functionality of popular wiki software such as MediaWiki and TWiki .
