Users now interact with multiple Location-Based Services (LBS) through a myriad set of location-aware devices and interfaces. However, current LBS tend to be centralized silos with ad-hoc APIs, which limits potential for information sharing and reuse. Further, LBS subscriptions and user experiences are not easily portable across devices. We propose a general architecture for providing open and decentralized access to LBS, based on Tiled Feeds -a RESTful protocol for access and interactions with LBS using feeds, and Feed Subscription Management (FSM) -a generalized feed-based service management protocol. We describe two client designs, and demonstrate how they enable standardized access to LBS services, promote information sharing and mashup creation, and offer service management across various types of location-enabled devices.

“…Switching map providers (say, to Yahoo, Bing, or OpenStreetMaps), or to load additional data (say, navigation) from some other source, is non-trivial. A more robust way, using standard Web technologies and architectures, would provide a declarative notion of location information and allow clients to integrate services as needed [8]. The recently standardized geo URI scheme [10] is a first step in that direction.…”

Personalized location-based services

Location-Based Services (LBS) are based on a combination of the inherent location information about specific data, and/or the location information supplied by LBS clients, requesting location-specific and otherwise customized services. The integration of location-annotated data with existing personal and public information and services creates opportunities for insightful new views on the world, and allows rich, personalized, and contextualized user experiences. One of the biggest constraints of current LBS is that most of them are essentially vertical services. These current designs makes it hard for users to integrate LBS from a variety of service providers, either to create intermediate value-added services such as social information sharing facilities, or to facilitate client-side aggregations and mashups across specific LBS providers. Our approach, the Tiled Feeds architecture, applies the well-established, standard Web service pattern of feeds, and extends it with query and locationbased features. Using this approach, LBS on the Web can be exposed in a generalized and aggregation-friendly way. We believe this approach can be used to facilitate the creation of standardized, Web-friendly, horizontally integrated location-based services.

Scalable and Mashable Location-Oriented Web Services

Abstract. Web-based access to services increasingly moves to locationoriented scenarios, with either the client being mobile and requesting relevant information for the current location, or with a mobile or stationary client accessing a service which provides access to location-based information. The Web currently has no specific support for this kind of service pattern, and many scenarios use proprietary solutions which result in vertical designs with little possibility to share and mix information across various services. This paper describes an architecture for providing access to location-oriented services which is based on the principles of Representational State Transfer (REST) and uses a tiling scheme to allow clients to uniformly access location-oriented services. Based on these Tiled Feeds, lightweight access to location-oriented services can be implemented in a uniform and scalable way, and by using feeds, established patterns of information aggregation, filtering, and republishing can be easily applied.
