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.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
providing a plurality of data source application programming interfaces (API) to API creators, each of the APIs providing an interface to one or more data sources;
allowing the API creators to create a composite API that allows users to access multiple data source APIs using a single query, the composite API configured to generate intermediate queries to two or more intermediate APIs, wherein each intermediate API is configured to retrieve information from an associated data source based upon an intermediate query and to provide the information to the composite API, the composite API configured to return information from two or more data sources in response to the single query, wherein the response is in a format not available from any of the individual data sources; and
offering the composite API to users.

2. The computer-implemented method of claim 1 , further comprising:
identifying query parameters accepted by the composite API; and
identifying response parameters provided by the composite API.

3. The computer-implemented method of claim 2 , further comprising:
receiving a user selection of one or more query parameters and one or more response parameters to be used with the composite API.

4. The computer-implemented method of claim 1 , further comprising:
identifying, to the composite API, locations of one or more data sources required by the composite API.

5. The computer-implemented method of claim 1 , further comprising:
identifying one or more data sources that are available to users via the composite API.

6. The computer-implemented method of claim 1 , further comprising:
identifying one or more data sources that are required for use with the composite API.

7. The computer-implemented method of claim 1 , further comprising:
identifying a plurality of data sources that are available to users via the composite API; and
receiving information required to access to one or more of the plurality of data sources.

8. The computer-implemented method of claim 1 , wherein the selected APIs use a standardized protocol for querying data.

9. The computer-implemented method of claim 8 , wherein the protocol is Open Data Protocol (OData).

10. The computer-implemented method of claim 1 , further comprising:
combining billing requirements for the selected APIs into a billing model for the composite API.

11. The computer-implemented method of claim 1 , further comprising:
identifying a group of end-user license terms for each of the selected APIs; and
combining the end-user license terms for each of the selected APIs into a composite end-user license agreement (EULA) for the composite API.

12. The computer-implemented method of claim 1 , further comprising:
offering the composite API to users via a website.

13. The computer-implemented method of claim 1 , further comprising:
providing a data marketplace to users, the data marketplace offering a plurality of APIs; and
allowing users to upload the composite API to the data marketplace to be offered to other users.

14. In a computing environment where resources are distributed, a method for accessing datasets on resources distributed in the computing environment, the method comprising:
selecting a composite application programming interface (API) executing on a processor that provides access to one or more datasets through a plurality of intermediate APIs;
identifying the one or more datasets to the composite API;
providing a query to the composite API; and
receiving a response from the composite API, the response generated using data collected from the one or more datasets via the plurality of intermediate APIs, wherein the composite API is configured to provide an output resulting from the query to an intermediate API, and wherein the intermediate API is configured to convert the output into a format required by at least one of the plurality of APIs.

15. The method of claim 14 , further comprising:
selecting one or more query parameters to be supported by the composite API; and
selecting one or more response parameters to be supported by the composite API.

16. The method of claim 14 , wherein the one or more datasets comprise optional datasets, and the method further comprising:
selecting at least one of the optional datasets for use with the composite API.

17. The method of claim 14 , wherein the one or more datasets are identified using one or more of a pointer, an address, a file name, and a uniform resource locator (URL).

18. The computer-implemented method of claim 14 , further comprising:
providing a virtual marketplace offering at least one composite API;
receiving a subscriber query to a selected composite API via the virtual marketplace; and
providing a response from the composite API to the subscriber via the virtual marketplace.

19. A computer-readable storage device storing computer-executable instructions that when executed by at least one processor cause the at least one processor to perform a method for accessing datasets, the method comprising:
providing a plurality of data source application programming interfaces (API) to users, each of the APIs providing an interface to one or more data sources; and
allowing API creators to create a composite API that allows users to access multiple data source APIs using a single query, the composite API configured to generate intermediate queries to two or more intermediate APIs, wherein each intermediate API is configured to retrieve information from an associated data source based upon an intermediate query and to provide the information to the composite API, the composite API configured to return information from two or more data sources in response to the single query, wherein the response is in a format not available from any of the individual datasets.

20. The computer-readable storage device of claim 19 , further comprising:
receiving a user selection of a composite API; and
identifying, to the user-selected composite API, locations of one or more data sources to be accessed by the composite API.

21. The computer-readable storage device of claim 19 , further comprising:
combining billing requirements for the selected APIs into a billing model for the composite API.

22. The computer-readable storage device of claim 19 , further comprising:
identifying a group of end-user license terms for each of the selected APIs; and
combining the end-user license terms for each of the selected APIs into a composite end-user license agreement (EULA) for the composite API.

23. The computer-readable storage medium of claim 19 , further comprising:
allowing users to upload the composite API to a data marketplace to be offered to other users.

24. A dataset access system, comprising:
a processor; and
a memory coupled to the processor, the memory configured to store program instructions executable by the processor to cause the dataset access system to:
select a composite application programming interface (API) that provides access to one or more datasets through a plurality of APIs;
identify the one or more datasets to the composite API;
provide a query to the composite API; and
receive a response from the composite API, the response generated using data collected from the one or more datasets via the plurality of APIs, wherein the composite API is configured to provide an output resulting from the query to a first intermed
