Towards a Wiki Interchange Format (WIF) Opening Semantic Wiki Content and Metadata

Wikis are increasingly being used in world-wide, intranet and even in personal settings. Unfortunately, current wikis are data islands: people can read and edit them, but machines can only send around text strings without structure. Wiki migration, publishing from one wiki to another one and free choice of syntax hold back broader wiki usage. We define a wiki interchange format (WIF) that allows data exchange between wikis and between related tools. Different from other approaches, we also tackle page content and semantic annotations. The linking from formal annotations to parts of a structured text is analysed and described.
