Abstract

A method and system are provided for defining a search space of a community in which a client may search for resources. A client providing a resource registers the resource with a core. The core then lists the resource with an advertising service, which serves multiple cores. A client searching for a resource can search in the client'"'"'s core and within the advertising service serving the clients core. In addition, a client searching for resources can define a community of advertising services remote to the client'"'"'s core, then designate the community when sending an attribute-based search for computer resources to the client'"'"'s core. In some embodiments, once a community is defined, a client can subscribe to an events within the community by searching for an event distributor within the community. The client is then notified of events occurring within the community that match the client'"'"'s event subscription.

Claims

1. A system for defining a search space, the system comprising:

a system core comprising one or more computers connected by a communication network;

a system core computer program executable by the system core, the system core computer program comprising computer instructions for;

receiving from a client a community name corresponding to a community;

receiving from the client an identification of an advertising service; and

adding the advertising service to the community, wherein the community comprises at least one advertising service that is remote to the client, where the advertising service is configured to service at least one core that is associated with a second client that is remote to the client, where the core comprises a protection domain for managing the second client, and where the core checks if a requesting client can access a resource of the second client.

2. The system of claim 1 wherein the system core computer program further comprises computer instructions for

setting the community as the client'"'"'s default community.

3. The system of claim 1 wherein an identification of an advertising service comprises a host name and a port number corresponding to a machine hosting the advertising service.

4. The system of claim 1 wherein the advertising service is associated with a plurality of cores and lists a resource available from one of the associated cores.

5. The system of claim 1 wherein the system core computer program further comprises computer instructions for:

receiving a query from the client to be run in the community; and

sending the query to each advertising service in the community.

6. The system of claim 5 wherein the query comprises an attribute of a resource.

7. The system of claim 5 wherein the system core computer program further comprises computer instructions for:

receiving from an advertising service in the community of an identification of a resource handler corresponding to a resource matching the query.

8. The system of claim 1 wherein the system core computer program further comprises computer instructions for:

receiving an event subscription request from the client; and

sending the event subscription request to an event distributor resource.

9. The system of claim 8 wherein the event subscription request comprises a community name and an attribute of an event.

10. The system of claim 8 wherein the system core computer program further comprises computer instructions for:

receiving from the event distributor of an event matching the event subscription request.

11. A method for defining a search space in a system core comprising one or more computers connected by a communication network, the method comprising:

receiving, from a client, a community name corresponding to a community;

receiving, from the client, an identification of an advertising service; and

adding the advertising service to the community, wherein the community comprises at least one advertising service that is remote to the client, where the advertising service is configured to service at least one core that is associated with a second client that is remote to the client, where the core comprises a protection domain for managing the second client, and where the core checks if a requesting client can access a resource of the second client.

12. The method of claim 11 further comprising:

setting the community as the client'"'"'s default community.

13. The method of claim 11 wherein receiving an identification of an advertising service comprises receiving an identification of an advertising service comprises receiving a host name and a port number corresponding to a machine hosting the advertising service.

14. The method of claim 11 wherein the advertising service is associated with a plurality of cores and lists a resource available from one of the associated cores.

15. The method of claim 11 further comprising:

receiving a query to be run in the community; and

sending the query to each advertising service in the community.

16. The method of claim 15 wherein receiving a query comprises receiving an attribute of a resource.

17. The method of claim 15 further comprising:

receiving an identification of a resource handler corresponding to a resource matching the query.

18. The method of claim 11 further comprising:

receiving an event subscription request from the client; and

sending the event subscription request to an event distributor resource.

19. The method of claim 18 wherein receiving an event subscription request comprises receiving a community name and an attribute of an event.

20. The method of claim 18 further comprising:

receiving from the event distributor an event matching the event subscription request.
