Abstract: Techniques for storing information representing a venue are described. A venue data provider may upload venue data to a venue data service. The venue data can include locations, geometries, and business categories of the buildings and floors. The venue data service can validate the venue data, and request a survey service to survey the venue using the validated venue data. A survey can include recording measurements of an environment variable at various locations of the venue. The location service can generate location fingerprint data from the survey. The location fingerprint data can include expected measurements of the environment variable at various locations of the building. The venue data service can provide the location fingerprint data to a mobile device such that the mobile device can determine a location of the mobile device in the venue using sensor readings of the environment variable.

Abstract: Techniques are disclosed for development of code for deployment on target devices within native code containers that provide access to native resources on the target devices. The native code containers on the target devices may provide only limited development capabilities. Thus, the disclosed development techniques may make use of a device that offers extended development capabilities in comparison to the native code containers on the target devices. A bridge may be established to connect an extended development capability device to a target device. The disclosed bridge may allow developers to benefit from extended development capabilities, while also enabling certain appropriate features to be tested on the target device in the environment in which they will eventually be used.

Abstract: Disclosed are various embodiments for taking measurements associated with the execution of an application on one or more client devices. A measurement policy and/or a transmission policy may be defined by a developer with associated with an application. The measurement policy and/or transmission policy may be used by the one or more client devices in taking measurements, aggregating measurements into measurement collections, and/or transmitting measurements. The measurements may be used in the derivation of statistical information.

Abstract: This disclosure is directed to providing notifications to mobile devices, which may piggy-back on other communications exchanged between a mobile device and one or more servers. By piggy-backing, or otherwise adding small amounts of additional data to routine communications, the mobile device may avoid polling the server for notifications of pending messages for the mobile device or reduce a frequency of polling for the notifications. When polling is used to supplement the piggy-backing, a frequency of the polling may be based on a variable threshold amount of time.

Abstract: Techniques for enriching venue data are described. The venue data can include records describing physical features of a venue and records describing conceptual features of the venue. A data enrichment engine can enrich the venue data using probe data by automatically correcting inconsistencies in the venue data or adding additional information to the venue data. The probe data can include crowd-sourced data from multiple mobile devices. The probe data can include motion sensor data, application launch data, and site survey data.

Abstract: Techniques for validating venue data are described. The venue data can include records describing physical features of a venue and records describing conceptual features of the venue. A validation engine can detect conflicts between records in the venue data or conflicts between records in the venue data and external data. The conflict can include a physical conflict between two physical features, e.g., when a floor of a building is larger than a footprint of the building, a conceptual conflict between two occupants of a venue, e.g., when an airport baggage claim area is located next to a high school, or a relationship conflict between an occupant and a venue in which the occupant is allegedly located, e.g., ski resort located in an office building. The conflict can be defined in conflict rules. The validation engine can learn the conflict rules from historical venue data and truth references.

Abstract: Disclosed are various embodiments for an ingestion process modifying digital items. A computing system receives an uploaded digital item configured to communicate with a testing server application when executed. The ingestion process reconfigures the digital item to communicate with a production server application when executed.
