Abstract: Data is published by publishers to an information service configured to receive data sets and allow consumers to consume the data sets via queries. Structural information of the data sets (e.g., column information) is presented to the publishers to select which information of the data sets can be a search parameter and which information can be returned in query results. Query interfaces are automatically created based on the selections by the publisher, and the back end databases are optimized for such query interfaces, e.g., creation of indexes based on the search parameters or query results selected by the publisher. A query aggregator can automatically combine a given query interface with other query interfaces to form more complicated (but still permitted) queries based on the intersection of permissions for the given query interface and the other query interfaces.

Abstract: Embodiments are directed to providing access to supplemental query data that is relevant to a data query. In one scenario, a computer system receives an input indicating that a data query is to be processed, where the input provides various search criteria. The computer system then generates the data query according to the search criteria in the received input. The computer system further sends the data query to a second computer system which is configured to process the data query and receives the results of the data query. The results indicate that additional data elements relevant to the search criteria have been identified. The computer system then displays an indication of various steps that are to be taken in order to access the identified additional data elements.

Abstract: Embodiments are directed to establishing a metadata repository that aggregates metadata for a plurality of data sources, inferring data source metadata at a metadata repository and to providing recommendations to data managers based on aggregated inputs. In one scenario, a computer system establishes a reference to one or more data sources, where each data source includes data elements. The computer system receives a data request for specified data elements stored on the data sources and accesses the established references to determine which data source the specified data elements are stored on. The computer system then retrieves at least one of the specified data elements from its determined data source and sends the retrieved data elements to a specified computer system, along with an indication of additional data elements that are relevant to the received data request, and a further indication of how those additional data elements are to be accessed.

Abstract: Embodiments described herein are directed to generating and displaying a user interface that allows data managers to provide supplemental metadata for data sources. In one scenario, a computer system generates a UI that shows an indication of data elements to which a metadata catalog is linked. The metadata catalog includes references to different data sources that store data elements. The UI receives an input indicating that metadata for at least one of the data sources is to be modified. The modification includes providing additional metadata for a specified data source, providing documentation for a specified data source and/or providing an entry point for an access request workflow. The computer system performs the received data source metadata modification according to the received input and, upon determining that the metadata has been modified, displays the updated metadata for the data sources in the UI.

Abstract: Tracking lineage of data. A method may be practiced in a network computing environment including a plurality of interconnected systems where data is shared between the systems. A method includes accessing a dataset. The dataset is associated with lineage metadata. The lineage metadata includes data indicating the original source of the data, one or more intermediary entities that have performed operations on the dataset, and the nature of operations performed on the dataset. A first entity performs an operation on the dataset. As a result of performing a first operation on the dataset, the method includes updating the lineage metadata to indicate that the first entity performed the operation on the dataset. The method further includes providing functionality for determining if the lineage metadata has been compromised in that the lineage metadata has been at least one of removed from association with the dataset, is corrupted, or is incomplete.

Abstract: A location collection system is described herein that provides a uniform facility for reporting location data to a cloud-based service from a variety of devices, and that provides a uniform facility for accessing aggregated location data collected by the cloud-based service. The system collects location information related to a user and reports the location information to a central service to provide a variety of useful services to the user. By providing a big, secure location vault in the cloud, the system enables big data analytics to be used to allow current and future questions to be asked of this data and to correlate this with other data to enable new scenarios not yet enabled. Thus, the location collection system provides a model to report, gather, and analyze location data across devices and users.

Abstract: Embodiments are directed to selecting and applying data-specific presentations, to adaptively selecting visual presentations based on historical data and to providing rendering hints for data presentations. In one scenario, a computer system receives an indication that a visual presentation is to be applied to a specified portion of data. The computer system analyzes the specified data to determine which of a plurality of data presentations is most relevant for the specified data. The relevance is based on relevancy factors including one or more of the following: end-user profile, structure of the specified data and patterns within the specified data. The computer system then applies the determined appropriate visual presentation to the specified data.

Abstract: Querying a finite set of data sources. A method includes receiving a query from a user. The method further includes determining a set of two or more data sources from the finite set of data sources that together can be used to satisfy the query. The method further includes translating at least a portion of the query from the user to semantically appropriate queries for the two or more data sources. The method further includes receiving results from the two or more data sources to the semantically appropriate queries. The method further includes aggregating the results, and presenting the aggregation to the user.

Abstract: Brokering requests between a user and a content provider. Methods include receiving, at the middleware system, a request for data from a user that is formatted in a first request format and requests data from a content provider. The request is translated to a second request format that is compatible with the content provider and sent to the content provider. A response is received from the content provider that includes hierarchically-structured content. The hierarchically-structured content is converted into tabular content by performing first queries on the hierarchically-structured content to identify repeating nodes, and mapping the repeating nodes to rows in the tabular format, and by performing second queries on the hierarchically-structured content to identify individual columns in the tabular format.

Abstract: Individual datasets are accessed using an application programming interface (API). Multiple APIs may be combined into a composite API that allows a user to access multiple datasets using a single query. The composite API may be designed to provide a simpler way to consume information from multiple datasets in response to a particular scenario or problem. The composite API may comprise multiple levels of intermediate APIs that call on each other to access desired datasets. A user may select the datasets that the composite API accesses and/or the composite API may require certain specific datasets. The composite API may be offered for sale or use by other users via a website, such as a data market.

Abstract: Embodiments are directed to providing a plurality of data provisioning tiers for datasets and to throttling access to dataset data based on the dataset's data provisioning tiers. In an embodiment, a computer system receives an input that specifies a maximum number of queries that a user is allowed to perform on a given dataset over a specified period of time. The computer system generates data provisioning tiers for the dataset based on the received input. Each data provisioning tier indicates a maximum number of queries that the user is allowed to perform on a given dataset over a specified period of time. The computer system also applies the generated data provisioning tiers to the dataset so that the user is limited to the maximum number of queries specified in the data provisioning tier.

Abstract: Methods, systems, and computer program products are provided for enabling users to enhance datasets available at a data service. A data service maintains and publishes datasets provided by content providers. Users may be enabled to annotate datasets maintained by the data service, and to extend the datasets. A suggestion of a dataset may be provided to users based on information received from a community of users. Users may be enabled to generate assets, such as reports and applications, based on one or more datasets of the data service. Furthermore, users may be enabled to share annotated datasets and/or extended datasets in websites, applications, and devices.

Abstract: A data fulfillment system is described herein that identifies data needs of data marketplace consumers and actively seeks out and attempts to fulfill those needs by adding new data and data providers to the marketplace. After a user enters a search, the system captures the search term(s). If no matching data is found, the data fulfillment system presents to the consumer a screen to suggest a new data offering and to provide a description of data for which the consumer was looking. The system then mines these consumer wants to seek partnerships programmatically by seeing who has this data or operates in this space. Thus, the data fulfillment system provides implicit and explicit ways for consumers to provide information describing data offerings that they want and for potential providers to learn about opportunities to fill current data gaps.

Abstract: The subject disclosure is directed towards a technology by which data sensed at a device may be used to determine the likely location of the device, independent of whether GPS data is also available. In one aspect, information representing the sensed device data is sent to a remote service, where it is compared with similar information for known locations to find a matching location. In another aspect, the information is locally processed against locally cached information to find a matching location.

Abstract: A single integrated offering includes a dataset license and a license to an application tailored for using the dataset. The dataset licensor and the application licensor are distinct entities. However, the integrated offering is electronically purveyed under a single offering price, in a public online marketplace and/or on licensor websites. In some cases, purveyance includes obtaining a purchaser's consents to the licenses, disclosing one or both of the licensors' identities, provisioning a purchaser with the dataset and the application, making payments to licensors, tax authorities, and/or other parties in response to a purchaser's payment, and reporting dataset/application usage to the licensors. Purveyor code permits cancelation of a purchase of the integrated offering only as a unified whole.
