Location has become an important concept for many Web-based applications, in particular because of the increasing popularity of mobile Internet access. So far, however, location concepts are reinvented in many different places and these diverging concepts make it hard to use location-based services and data in a truly open way. The Second International Workshop on Location and the Web (LocWeb 2009) targets the capabilities and constraints of Web-based location-oriented services, looking at browser-based applications, as well as at native applications using Web services. The focus of this workshop is on exploring approaches for handling the complexity of location-based services and, more specifically, looking at location abstractions, location sharing, privacy issues, and interface design issues.
