Abstract

A document manager runs at a client computer and retrieves documents downloaded from a server computer across a communications medium. The documents can contain embedded links to objects, which are building blocks that make up or are associated with the documents. The client computer keeps a local copy of a standard-set of objects, so that when the client computer needs to present the linked objects to the user, the linked objects that are part of the standard-set do not need to be retrieved from the server by the client. When a linked object is needed, the document manager parses the embedded link to the object and extracts the file name of the object. The document manager then searches a name list, which contains all the names of objects in the standard-set. If the file name from the link is in the name list, the document manager uses the object of the same name in the local copy of the standard-set. If the file name is not in the name list, the document manager retrieves the linked object using the full embedded link.

Claims

1. A document manager for operation at a client computer, wherein the client computer is connected via a network to a document-server computer, the document manager comprising:

a name list of a plurality of objects in a standard-set, wherein the standard-set objects contain information for presentation to a user of the client computer; and

a browser that receives a document from the document-server computer, wherein the document comprises at least one embedded link, wherein the embedded link specifies an address of a linked object, and wherein the address points to an object-server computer in the network,

and wherein the browser extracts a file name of the linked object from the embedded link,

and wherein the browser determines whether the file name exists in the name list,

and when the file name is not in the name list, the browser uses the address to retrieve the linked object from the object-server computer and presents information in the linked object and information in the document to the user,

and when the file name is in the name list, the browser substitutes a corresponding standard-set object for the linked object and presents information in the corresponding standard-set object and information in the document to the user, wherein the corresponding standard-set object has a name identical to the file name, and wherein the information in the corresponding standard-set object is different from the information in the linked object.

2. The document manager of claim 1, wherein the plurality of standard-set objects are located in the client computer.

17. A method in a client computer for browsing, wherein the client computer is connected via a network to a document-server computer, comprising the machine executed steps of:

receiving a document from the document-server computer, wherein the document comprises at least one embedded link, wherein the embedded link specifies an address of a linked object, and wherein the address points to an object-server computer in the network;

extracting a file name of the linked object from the embedded link;

determining whether the linked object has a corresponding object in a plurality of standard-set objects by comparing the file name of the linked object to the names of the plurality of standard-set objects;

when a corresponding standard-set object does not exist in the plurality of standard-set objects, using the address to retrieve the linked object from the object-server computer and presenting information in the linked object to a user; and

when the corresponding object does exist in the plurality of standard-set objects, substituting a corresponding standard-set object for the linked object and presenting information in the corresponding standard-set object to the user instead of retrieving the linked object, and wherein the information in the corresponding standard-set object is different from the information in the linked object.

18. The method of claim 17, wherein the information in the corresponding standard-set object is customized to the language of the user of the client computer.

19. The method of claim 17, wherein the object-server computer equals the document-server computer.

20. The method of claim 17, wherein the object-server computer is different from the document-server computer.

21. The method of claim 17, wherein the information in the corresponding standard-set object is video.

22. The method of claim 17, wherein the information in the corresponding standard-set object is audio.

23. The method of claim 17, wherein the information in the corresponding standard-set object is graphic.

24. The method of claim 17, wherein the information in the corresponding standard-set object is text.

25. The method of claim 17, wherein the information in the corresponding standard-set object is code.

26. The method of claim 17, further comprising initially loading the plurality of standard-set objects from secondary storage associated with the client computer.

27. The method of claim 17, further comprising initially loading the plurality of standard-set objects from a standard-set server computer connected to the network.

28. The method of claim 17, further comprising providing the user with an option of selecting which subset of the plurality of standard-set objects to use wherein the standard-set objects comprise a plurality of subsets each customized for a different language.

29. The method of claim 17, further comprising adding the linked object to the plurality of standard-set objects.
