The document describes a hybrid and semantic location management system (HS-LMS) for mobile user-generated geo services (MUGGES). The HS-LMS allows for a consistent location concept between micro-applications called "mugglets" by mapping different location aspects like coordinates, symbols, and semantics. It also enables reasoning between related locations through ontologies describing political, administrative, and geographic relationships. The system aims to provide better search capabilities and attribute information for mugglets through relationships defined in the location ontologies.
