A system for capturing and delivering location-based information and services captures wireless landmark information sent by mobile devices to build a map of locations based on the relationship between wireless landmarks that are visible to the mobile device at the same time. A wireless landmark may be a cellular telephone base site or local network (WiFi/Bluetooth) access point. The mobile device may capture a location signature using identifiers for all wireless local area networks in range as well as one or more cellular telephone transmitters. A location service resolves the location signature into a relative location that an application service may use to record incoming information or to send location-specific information such as traveler comments, reviews, or advertisements. The distance between two mobile devices may be calculated using weighted edge values, representing a number of 'hops' between location signatures.

WiFi and GSM landmarks and neighborhoods for location based services

A programming model that takes general purpose APIs and machine-generates new programming models based on user defined schemas that provide the developer with data and view separation, and a way to communicate to the host application using the domain of the problem being solved. The system comprises a schema component that the developer uses to define a schema that includes one or more domain terms related to the problem to be solved, and a mapping component that uses the schema to search and map selected constructs from one or more generic host application APIs to the corresponding problem domain terms. Once the mapping is completed, a generating component generates a new API that is used by a host application to facilitate developing an application document using terms related to the domain of the problem to be solved.

Schema-based machine generated programming models

Architecture that facilitates the creation of a customized document with embedded or linked code that can be run on a client or a server without invoking the host application. A programming model makes it transparent to the code whether it is running on the client or the server. The programming model automatically 'scales' to provide more features while running the document on the client and fewer features when running on the server. A transparent data island is automatically generated for the customized document that is embedded in the document and can be edited while requiring only a subset of all components of the host application to be running. A data binding mechanism is provided wherein changes that are made to the transparent data island while the host is not running can be moved back into the host document content when the document is reopened by the full host application.
