Abstract

An improved method for enumerating resources for use by a client is described. In an exemplary embodiment, the method includes method steps of: storing a source set of resources; receiving a request from the client for resources appropriate for the client; based at least in part on the request, determining a type for the client; based at least in part on the determined type, determining capabilities of the client; determining possible media types that may be derived from the source set of resources that are appropriate for the client; based on the possible media types and based on the set of resources, generating an extended set of resources; communicating the extended set of resources to the client; and processing requests from the client for access to resources from the extended set of resources.

consulting a device capabilities database for determining particular capabilities of the client.

13. The method of claim 12, wherein said device capabilities database is at a remote location from the client.

14. The method of claim 1, wherein said step of determining possible media types appropriate for the client includes:

using a model number of the client to look up device capability information for the client.

15. The method of claim 14, wherein said model number is transmitted as part of said initial request.

16. The method of claim 1, wherein said step of determining possible media types includes:

determining a virtual set of possible media types that are appropriate for the client.

17. The method of claim 1, wherein said virtual set comprises a superset of resources that includes media types that resources from the source set may be transformed into.

18. The method of claim 17, wherein said virtual set includes at least one image format that may be derived from an image format in the source set of resources.

19. The method of claim 18, wherein at least one image format is derived from an image format in the source set of resources using an image transformation.

20. The method of claim 19, wherein said image transformation includes transforming from a non-JPEG format to a JPEG-compatible format.

21. The method of claim 19, wherein said image transformation includes transforming from one bitmap format to another.

22. The method of claim 1, wherein said step of determining an extended set of resources includes:

determining an intersection between the source set of resources and said possible media types.

23. The method of claim 22, further comprising:

specifying preferred media types for the client; and

constraining the extended set of resources to only include preferred media types for the client.

24. The method of claim 23, wherein preferred media types for the client are specified by the client when requesting access to resources.

25. The method of claim 23, wherein preferred media types for the client are specified by a device capabilities database.

26. The method of claim 23, wherein preferred media types for the client are specified by a server that receives requests from the client.

27. The method of claim 26, wherein preferred media types for the client are specified at the time the client requests access to a particular resource from the extended set of resources.

28. The method of claim 1, wherein the client includes a mobile device running application software.

29. The method of claim 1, wherein the client includes a precompiler that binds resources to an application.

30. The method of claim 1, further comprising:

upon receiving a request from the client for access to a resource from said extended set of resources, creating the resource by transforming one of the resources from the source set of resources into a resource having a media type appropriate for the client.

31. The method of claim 1, wherein said step of determining an extended set of resources further comprises:

applying convergence to the extended said of resources in instances where resources may be combined together into fewer resources.

32. The method of claim 1, wherein said step of communicating information about the extended set of resources to the client includes:

transmitting a directory of virtual resources to the client.

33. The method of claim 32, wherein said client is unaware that the resources indicated on the directory are derived from the source set of resources.

34. The method of claim 1, further comprising:

upon receipt of a request for access to a resource, determining whether the resource belongs to a related group of resources; and

if the resource belongs to a related group of resources, enforcing a group-wide constraint on the resources.

35. The method of claim 34, wherein said group-wide constraint includes constraining resources belonging to the group to share a common palette.

36. The method of claim 1, wherein said step of determining possible media types appropriate for the client includes:

based at least in part on the request, determining a type for the client; and

based at least in part on the determined type, determining capabilities of the client.

37. The method of claim 36, wherein said type comprises a device type.

38. The method of claim 36, wherein said type comprises a browser type.
