Abstract

A system and method for controlling generation of and access to localized application values to applications. The system includes an administrative interface linked to a running application and to a communications network that is configured for receiving requests for application data from the application. The interface responds by determining obtaining localized application values from a cache or if not cached, from a central database or repository of network localized application values that is also linked to the communications network. Code or mechanisms are provided for creating and populating data structures or objects for storage in the cache. Mechanisms or background threads are also provided for monitoring changes to localized application values in the repository and automatically updating element values in the cache as and when they change.

Claims

1. A computer system for providing localized application data to computing devices linked to a data communications network, comprising:

a client device linked to the communications network including a running application, an administrative interface in communication with the application and the communications network, and a local memory for storing localized application values used by the application; and

an application value repository linked to the communications network for storing localized application values used by the computing devices;

wherein the administrative interface is operable to receive a request from the application for application values and to respond by selectively retrieving the localized application values corresponding to the request from the local memory and the application value repository, wherein the localized application values are selected based upon a geographical area and a language selection included in the request, and wherein the application localized values stored in the application value repository include property values.

2. The computer system of claim 1, wherein the client device further includes an update mechanism operable to monitor the localized application values at the application value repository and to update the localized application values in the local memory.

3. The computer system of claim 1, wherein the localized application values stored in the local memory are selected based on prior requests from the application and are removed from the local memory when a last accessed time parameter indicates a period of inactivity has been exceeded.

4. The computer system of claim 1, wherein the client device further includes a mechanism operable to generate a localized eXtensible Markup Language (XML) file comprising at least a portion of the localized application values.

5. The computer system of claim 4, wherein the application value repository further stores a stylesheet that is adapted for combining with the XML file to produce a localized stylesheet.

6. The computer system of claim 1, wherein the localized application values include user roles indicating data access levels for users of the application, the user roles being localized to allow variation based on geographical locations selected by the users of the application and being used by the administrative interface in the selective retrieving of the localized application values.

7. The computer system of claim 1, further comprising a second client device linked to the communications network running the application, wherein users of the second client device select different geographical areas than the client device and wherein the localized application values retrieved by the second client device from the application value repository differ from the localized application values retrieved by the client device based on the different geographical areas.

8. A method in a computer system for controlling generation of and access to localized application data, comprising:

receiving a request for application data from an application;

determining if localized application values corresponding to the request are present in local memory of the computer system;

when determined present, retrieving the localized application values from the local memory;

when determined not present, retrieving the localized application values from an application value repository; and

returning retrieved localized application values to the application;

wherein the request includes an application name, a geographical area code, a language code, and at least one element name which are used in the retrieving steps to provide localized application values matching the geographical area code and the language code.

9. The method of claim 8, further comprising when not present, creating an empty data structure, populating the data structure with the localized application values from the repository, and storing the populated data structure in the local memory.

10. The method of claim 9, wherein the data structure includes a list of element values appropriate for application name, geographical area, and language information provided in the request.

11. The method of claim 10, wherein the populating includes obtaining a geographical hierarchy from the repository and checking nodes in the geographical hierarchy for the listed element values beginning at a node corresponding to the supplied geographical area and language information and moving upward to and ending at a top node.

12. The method of claim 8, further including updating the localized application values in the local memory to reflect modifications to the localized application variables in the application value repository.

13. The method of claim 12, wherein the updating is performed at a time when the updating is determined to not affect performance of the application as perceived by a user of the application.

14. The method of claim 8, further including constructing a data structure from the retrieved localized application values and storing the constructed data structure.

15. The method of claim 14, further including monitoring for changes in the localized application values corresponding to the retrieved localized application values and repeating the constructing after a change is identified in the monitoring to create a refreshed data structure.

16. An interface for providing localized data to an application operating on a computer system, the interface comprising computer readable program code devices for:

receiving a request for application data from an application;

determining if localized application values corresponding to the request are present in a cache structure of the computer system, the localized application values comprising values specific to a geographical area and language identified in the request;

when determined present, retrieving the localized application values from the cache;

when determined not present, retrieving the localized application values from an application value repository; and

returning retrieved localized application values to the application.

17. A computer readable medium containing a data structure for storing and providing current localized application values to one or more applications running in a geographically disburse computer network, the data structure comprising:

an application cache storing application combinations representing each combination of names of the running applications, geographical areas utilized in the computer network, and codes identifying languages supported within the computer network;

an element value cache storing element values comprising localized application values required by the running applications, wherein each of the element values comprises a localized value for a node in a tree structure in which each of the nodes corresponds to a combination of a geographical area, a supported language, and a staged or released value.

18. The data structure of claim 17, further including an application user cache storing user roles that indicate for users of the applications the localized application values the users can access based on the staged or released value.
