Molly is an open-source framework for developing mobile portals based on open data. It aggregates information from various sources like OpenStreetMap, RSS feeds, and APIs to provide services like contact search, news, weather, library search, and transport information to mobile users. Originally developed at Bangor University and St. George's, University of London, Molly uses a RESTful API to allow native mobile apps to access this data and is focused on progressive enhancement for mobile devices.
