Many of the world's great museums, cultural heritage sites, and other tourist locations offer their visitors some sort of companion mobile app. These apps have features that range from providing basic information to detailed exhibit data, guided tours, interactive displays and augmented reality. With very few exceptions, these apps are purpose-built for each specific venue. We describe a general extensible framework for mobile location-based information systems that provides a complete infrastructure for building apps of this type, with which only content creation is required to make a full-featured, venue-specific mobile app, but further customization is also possible and simple.
