Ward Cunningham's vision for the wiki was that it would be "the simplest online database that could possibly work". We consider here a common manifestation of simplicity: the assumption that the objects in a wiki that can be edited (e.g., Wikipedia articles) are relatively independent. As wiki applications in new domains emerge, however, this assumption is no longer tenable. In wikis where the objects of interest are highly interdependent (e.g., geographic wikis), fundamental concepts like the revision and undoing must be refined. This is particularly so when fine-grained access control is required (as in enterprise wikis or wikis to support collaboration between citizens and government officials). We explore these issues in the context of the Cyclopath geowiki and present solutions that we have designed and have implemented or are implementing.
