Abstract

A method and system for accessing multiple types of content from a broad range of client program modules. A client program module can access multiple types of content without the client program module having a knowledge of what type of content it is accessing. A user can dynamically add or change services to the system. The method and system can also serve as a standard way of exchanging content between services and client program modules.

Claims

1-20. -20. (Cancelled)

21. A method of enabling a client program module to access one or more service containers that provide a total data content unknown to the client program module and not expected to be accessed by the client program module when the client program module was created, one or more service containers providing at least a partial data content that is unknown to the client program module, comprising the steps of:

(a) requesting a list of available service containers;

(b) creating the list of available service containers based on a common access privilege between the client program module and each service container;

(c) selecting a service container from the list of available service containers, wherein the service container selected includes the at least partial data content unknown to the client program module; and

(d) if the access to the at least partial data content enables the program module to access the total data content in the service container that was selected;

(i) initializing the service container selected such that the client program module is enabled to access and use the total data content;

else

(ii) selecting an other service container from the list of available service containers that comprises at least further partial data content unknown to the client program module and initializing the other service container selected such that the client program module is enabled to access and use the further partial data content of the other service container selected, and repeating this step as needed until the client program manager is enabled to access and use the total data content of the service containers selected.

22. The method of claim 21, further comprising the step of registering the service containers, which includes the steps of:

(a) writing loader identifications and object locations to a registry;

(b) adding files from the location corresponding to the loader identifications and object locations; and

(c) updating a cache file.

23. The method of claim 21, further comprising the step of initiating a service manager, which responds to a request for the list of available service containers by creating the list of available service containers.

24. The method of claim 21, wherein the step of creating the list of available service containers comprises the steps of:

(a) comparing privilege data of the client program module with privilege data of objects stored in a storage medium; and

(b) in response to a match between the privilege data of the client program module with the privilege data of the objects, recording each respective match in the list.

25. The method of claim 21, wherein the step of creating the list of available service containers comprises the steps of:

(a) comparing a cache file with a registry;

(b) updating the cache file to reflect the registry, if the cache file does not match the registry;

(c) determining services in the cache file that match a privilege identification of the client program module; and

(d) compiling a list of object locations, loader identification data, and objects in hierarchical order, from the cache file.

26. The method of claim 21, wherein the step of initializing the service container selected comprises the step of loading a plurality of service objects that comprise the service container selected.

27. The method of claim 26, wherein the service objects have a predefined relationship that includes one of the following:

(a) the service objects must be executed in a predefined order; and

(b) the service objects are in a master-slave relationship.

28. The method of claim 21, wherein the service container comprises at least one of:

(a) a code object that performs a specific function;

(b) an associated data object; and

(c) a loader identification.

29. The method of claim 21, wherein a service container that provides foreign language translation functionality as the at least partial data content comprises:

(a) a stemmer object;

(b) a look-up object; and

(c) a character set conversion object.

30. The method of claim 21, wherein the step of initializing comprises the step of managing one or more service containers such that the at least partial data content of each service container is passed bi-directionally between the service manager, the service container, a cache file, and the client program module, using a variant parameter and one of the following:

(a) a first method wherein a first variant parameter is input to the service container by the service manager and a second variant parameter is output from the service container to the service manager;

(b) a second method wherein the at least partial data content is passed into an object; and

(c) a third method wherein the at least partial data content is received by querying an object.

31. The method of claim 21, further comprising the step of instantiating the at least partial data content from one or more service containers using a cache file such that the total data content is accessed in the cache file.

32. A memory medium having machine executable instructions for carrying out the steps of claim 21.

33. A system that enables a client program module to access one or more service containers that provide a total data content unknown to the client program module and not expected to be accessed by the client program module when the client program module was created, one or more service containers providing at least a partial data content that is unknown to the client program module, comprising:

(a) a processor; and

(b) a memory coupled to the processor, the memory storing machine instructions causing the processor to;

(i) enable the client program module to request a list of available service containers;

(ii) create the list of available service containers based on a common access privilege between the client program module and each service container;

(iii) select a service container from the list of available service containers, wherein the service container selected includes the at least partial data content unknown to the client program module; and

(iv) if the access to the at least partial data content enables the program module to access the total data content in the service container that was selected;

(1) initialize the service container selected such that the client program module is enabled to access and use the total data content;

else

(2) select an other service container from the list of available service containers that comprises at least further partial data content unknown to the client program module and initialize the other service container selected such that the client program module is enabled to access and use the further partial data content of the other service container selected, and repeat this step as needed until the client program manager is enabled to access and use the total data content of the service containers selected.

34. The system of claim 33, wherein the machine instructions further cause the processor to register the service containers, by:

(a) writing loader identifications and object locations to a registry maintained in the memory;

(b) adding files from the location corresponding to the loader identifications and object locations; and

(c) updating a cache file in the memory.

35. The system of claim 33, wherein the machine instructions further cause the processor to initiate a service manager, which responds to a request for the list of available service containers by creating the list of available service containers.

36. The system of claim 33, wherein the machine instructions further cause the processor to:

(a) compare privilege data of the client program module with privilege data of objects stored in a storage medium; and

(b) in response to a match between the privilege data of the client program module with the privilege data of the objects, record each respective match in the list.

37. The system of claim 33, wherein the machine instructions further cause the processor to:

(a) compare a cache file with a registry maintained in the memory;

(b) update the cache file to reflect the registry, if the cache file does not match the registry;

(c) determine services in the cache file that match a privilege identification of the client program module; and

(d) compile a list of object locations, loader identification data, and objects in hierarchical order, from the cache file.

38. The system of claim 33, wherein the machine instructions further cause the processor to load a plurality of service objects that comprise the service container selected.

39. The system of claim 38, wherein the service objects have a predefined relationship that includes one of the following:

(a) the service objects must be executed by the processor in a predefined order; and

(b) the service objects are in a master-slave relationship.

40. The system of claim 33, wherein the service container comprises at least one of:

(a) a code object that performs a specific function;

(b) an associated data object; and

(c) a loader identification.

41. The system of claim 33, wherein a service container that provides foreign language translation functionality as the at least partial data content comprises:

(a) a stemmer object;

(b) a look-up object; and

(c) a character set conversion object.

42. The system of claim 33, wherein when the machine instructions further cause the processor to manage one or more service containers such that the at least partial data content of each service container is passed bi-directionally between the service manager, the service container, a cache file, and the client program module, using a variant parameter and one of the following:

(a) a first method wherein a first variant parameter is input to the service container by the service manager and a second variant parameter is output from the service container to the service manager;
