Abstract

A method is provided for accessing files on a client node which is connected to a server node across a network channel. A first file is displayed on the client node, and context information indicative of this first document is stored. Rather than using a “hard” link which specifies a specific path/filename, a dynamic softlinking process is used to access a second file. A link, similar to a hyperlink, can be selected on the first displayed file to access a second file, where the link includes information indicative of the second file. To determine a file identifier for the second document, a data structure, having a plurality of file identifiers, is accessed using the context information and link information. The second file can then be retrieved from the server node via the network channel using the file identifer and displayed on the client node.

Claims

1. A method of operating a vehicle diagnostic system in order to access files in a vehicle information system having at least one client node connected to a server node across a network channel comprising the steps of:

establishing a diagnostic session for a motor vehicle, including coupling a diagnostic tool between the vehicle diagnostic system and the motor vehicle;

accessing a first file on said client node, said first file having vehicle information for a first type vehicle;

identifying vehicle context information associated with said first file, said vehicle context information is indicative of said first type of vehicle;

selecting a softlink in said first file, where the softlink is indicative of subject matter information for a second file and the softlink is not a unique file identifier for said second file;

determining a unique file identifier for said second file based on said vehicle context information and said subject matter information;

retrieving said second file from said server node via said network channel using said unique file identifier;

accessing said second file on said client node;

saving said vehicle context information and said subject matter information for said second file in a session object, thereby facilitating retrieval of said second file at a later time.

2. The method of claim 1 wherein said step of determining a file identifier further comprises accessing a data structure using said vehicle context information and said subject matter information, thereby retrieving said file identifier.

3. The method of claim 1 wherein said context information includes one or more vehicle identifiers selected from a group consisting of a vehicle model identifier, a vehicle make identifier, a vehicle year identifier, a vehicle engine identifier, and a vehicle identification number.

4. The method of claim 1 wherein said client node comprises a computer-human interface module for accessing said first and said second file, and a memory accessible by said interface module for storing said context information.

5. The method of claim 1 wherein said first file and said second file are stored in a database residing on said server node and are retrieved by said interface module using said file identifier.

6. The method of claim 1 wherein at least one of said first file and said second file are stored in hypertext markup format and said link is further defined as a hyperlink.

7. A method of obtaining vehicle diagnostic information by browsing documents containing vehicle information using a vehicle information system, the vehicle information system having at least one client node connected to a server node across a network channel comprising the steps of:

establishing a diagnostic session for a motor vehicle, including coupling a diagnostic tool between the vehicle diagnostic system and the motor vehicle;

displaying a first document on a client node, said first document having vehicle information for a first type of vehicle;

identifying vehicle context information from said first document, said vehicle context information is indicative of said first type of vehicle;

selecting a hyperlink in said first document, where said hyperlink is indicative of subject matter information for a second document and said hyperlink is not a unique file identifier for said second document;

combining the vehicle context information from said first document and said subject matter information from said second document in order to form a unique file identifier for the second document;

retrieving said second document from said server node via said network channel using said unique file identifier; and

displaying said second document on said client node.

8. The method of claim 7 wherein said step of determining a file identifier further comprises accessing a data structure using said vehicle context information and said subject matter information, thereby retrieving said file identifier.

9. The method of claim 7 wherein said context information includes one or more vehicle identifiers selected from a group consisting of a vehicle model identifier, a vehicle make identifier, a vehicle year identifier, a vehicle engine identifier, and a vehicle identification number.

10. The method of claim 7 wherein said client node comprises a computer-human interface module for displaying said first document and said second document, and a memory accessible by said interface module for storing said context information.

11. The method of claim 7 wherein said first document and said second document are stored in a database residing on said server node and are retrieved by said interface module using said file identifier.

12. The method of claim 7 wherein at least one of said first document and said second document are stored in hypertext markup format, and said link is further defined as a hyperlink.
