Abstract

In an example embodiment, three roles are defined for each of the following: resource discovery: provider, aggregator, and consumer. The provider is the one whose resource information will be shared. Rather than the provider needing to implement the complicated API, however, an aggregator may provide that role. The aggregator defines the API and is able to gather resource information from potentially multiple providers (and also, in some embodiments, other aggregators). The consumer then accesses the aggregator to obtain resource information rather than directly accessing the provider.

Claims (49)

1. A system comprising:

at least one hardware processor; and

a computer-readable medium storing instructions that, when executed by the at least one hardware processor, cause the at least one hardware processor to perform operations comprising, at a resource discovery aggregator:

identifying an endpoint for a resource discovery provider;

issuing a request to the endpoint;

in response the issuing of the request, receiving a configuration file from the endpoint, the configuration file indicating one or more locations of one or more resource discovery documents and one or more access strategies that can be used to access the one or more resource discovery documents, each resource discovery document indicating one or more capabilities of the resource discovery provider, wherein the one or more capabilities are implemented as one or more Application Program Interfaces (APIs) separate and distinct from the resource discovery document;

comparing the one or more access strategies to a list of one or more access strategies supported by the resource discovery aggregator to identify at least one matching access strategy present in both the one or more access strategies in the configuration file and the list;

using the at least one matching access strategy and the one or more locations to access the one or more resource discovery documents;

storing, at the resource discovery aggregator, information from the one or more resource discovery documents;

receiving, from a resource discovery consumer, a request for capability information;

in response to the receiving, retrieving the capability information from the stored information; and

sending the capability information to the resource discovery consumer.

2. The system of claim 1 , wherein the one or more access strategies in the configuration file include at least one pull transport access strategy.

3. The system of claim 1 , wherein the one or more access strategies in the configuration file include at least one push transport access strategy.

4. The system of claim 1 , wherein the one or more access strategies in the configuration file include at least one event-based transport access strategy.

5. The system of claim 1 , further comprising periodically repeating the using the at least one matching access strategy to access the one or more resource discovery document and the storing of the information from the one or more documents.

6. The system of claim 1 , wherein a uniform resource indicator for the endpoint is registered with a registry.

7. The system of claim 6 , wherein the endpoint has a fixed relative uniform resource locator.

8. A method comprising, at a resource discovery aggregator:

identifying an endpoint for a resource discovery provider;

issuing a request to the endpoint;

in response the issuing of the request, receiving a configuration file from the endpoint, the configuration file indicating one or more locations of one or more resource discovery documents and one or more access strategies that can be used to access the one or more resource discovery documents, each resource discovery document indicating one or more capabilities of the resource discovery provider, wherein the one or more capabilities are implemented as one or more Application Program Interfaces (APIs) separate and distinct from the resource discovery document;

comparing the one or more access strategies to a list of one or more access strategies supported by the resource discovery aggregator to identify at least one matching access strategy present in both the one or more access strategies in the configuration file and the list;

using the at least one matching access strategy and the one or more locations to access the one or more resource discovery documents;

storing, at the resource discovery aggregator, information from the one or more resource discovery documents;

receiving, from a resource discovery consumer, a request for capability information;

in response to the receiving, retrieving the capability information from the stored information; and

sending the capability information to the resource discovery consumer.

9. The method of claim 8 , wherein the one or more access strategies in the configuration file include at least one pull transport access strategy.

10. The method of claim 8 , wherein the one or more access strategies in the configuration file include at least one push transport access strategy.

11. The method of claim 8 , wherein the one or more access strategies in the configuration file include at least one event-based transport access strategy.

12. The method of claim 8 , further comprising periodically repeating the using the at least one matching access strategy to access the one or more resource discovery document and the storing of the information from the one or more documents.

13. The method of claim 8 , wherein a uniform resource indicator for the endpoint is registered with a registry.

14. The method of claim 13 , wherein the endpoint has a fixed relative uniform resource locator.

15. A non-transitory machine-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform operations comprising, at a resource discovery aggregator:

identifying an endpoint for a resource discovery provider;

issuing a request to the endpoint;

in response the issuing of the request, receiving a configuration file from the endpoint, the configuration file indicating one or more locations of one or more resource discovery documents and one or more access strategies that can be used to access the one or more resource discovery documents, each resource discovery document indicating one or more capabilities of the resource discovery provider, wherein the one or more capabilities are implemented as one or more Application Program Interfaces (APIs) separate and distinct from the resource discovery document;

comparing the one or more access strategies to a list of one or more access strategies supported by the resource discovery aggregator to identify at least one matching access strategy present in both the one or more access strategies in the configuration file and the list;

using the at least one matching access strategy and the one or more locations to access the one or more resource discovery documents;

storing, at the resource discovery aggregator, information from the one or more resource discovery documents;

receiving, from a resource discovery consumer, a request for capability information;

in response to the receiving, retrieving the capability information from the stored information; and

sending the capability information to the resource discovery consumer.

16. The non-transitory machine-readable medium of claim 15 , wherein the one or more access strategies in the configuration file include at least one pull transport access strategy.

17. The non-transitory machine-readable medium of claim 15 , wherein the one or more access strategies in the configuration file include at least one push transport access strategy.

18. The non-transitory machine-readable medium of claim 15 , wherein the one or more access strategies in the configuration file include at least one event-based transport access strategy.

19. The non-transitory machine-readable medium of claim 15 , further comprising periodically repeating the using the at least one matching access strategy to access the one or more resource discovery document and the storing of the information from the one or more documents.

20. The non-transitory machine-readable medium of claim 15 , wherein a uniform resource indicator for the endpoint is registered with a registry.
