Abstract

A method of browsing electronically-accessible resources using descriptions of the resources. These descriptions have descriptor components, which have attributes representative of at least two axes of access to the resources. These descriptions also have links to the corresponding resources. The method first reads the descriptions and displays a number of items (1608). Each one of these items are associated with a corresponding descriptor component of the read description that has an attribute. The method allows the browsing (1602,1603) of the descriptions and their corresponding electronically-accessible resources via the links using the displayed items.

Claims

1. A method of browsing electronically-accessible resources using descriptions of the resources, said method comprising the steps of:

generating descriptions of the electronically-accessible resources, the generated descriptions being separate from the content of the resources and comprising descriptor components classified as either table-of-contents descriptor components or index descriptor components, each said table-of-contents descriptor component having a link to a corresponding portion of the electronically-accessible resources;

displaying items for selection, each displayed item corresponding to a table-of-contents descriptor component of a generated description;

receiving a selection of one or more of said displayed items;

displaying further items for selection, the further items corresponding to index descriptor components that are associated with one or more table-of-contents descriptor components corresponding to the selected one or more of said displayed items;

receiving a selection of one of said displayed further items;

providing a representative value associated with said selected further item;

forming a query from the index descriptor component corresponding to said selected one of said displayed further items and said provided representative value;

searching said generated descriptions to return one or more table-of-contents descriptor components that satisfy said query and are contained in the one or more table-of-contents descriptor components corresponding to the selected one or more of said displayed items; and

displaying for selection one or more still further items corresponding to said returned one or more table-of-contents descriptor components.

2. The method as claimed in claim 1, wherein each generated description is represented in a tree of descriptor components, and one or more of the descriptor components have descriptor components as descendants.

3. The method as claimed in claim 1, comprising the further step of viewing, in response to a selection of one of said still further displayed items, the portion of the electronically-accessible resources corresponding to a returned table-of-contents descriptor component linked to by the selected one of said still further displayed items.

4. The method as claimed in claim 1, wherein the descriptions of the electronically-accessible resources are generated using a description scheme as a template, and the description scheme uses a declarative description definition language which contains definitions for descriptor components of the generated descriptions of the electronically-accessible resources.

5. The method as claimed in claim 4, wherein the attributes of the descriptor components are defined in the description scheme.

6. The method as claimed in claim 4, wherein the attributes of the descriptor components are persistent items of the description scheme.

7. The method as claimed in claim 4, wherein the attributes of the descriptor components are instantiated by an application when required.

8. The method as claimed in claim 7, wherein the attributes of the descriptor components are instantiated using a rule that is associated with the description scheme.

9. The method as claimed in claim 1, wherein the electronically-accessible resources comprise digital audiovisual content.

10. The method as claimed in claim 1, wherein the electronically-accessible resources comprise an electronic document or resource available over the World Wide Web.

11. The method as claimed in claim 1, wherein the electronically-accessible resources comprise information about an electronic device.

12. The method as claimed in claim 1, wherein a descriptor component is classified to be a table-of-contents descriptor if the descriptor component contains a reference to a resource or a section of a resource.

13. The method as claimed in claim 12, wherein a descriptor component is classified to be an index descriptor if the descriptor component is not classified to be a table-of-contents descriptor.

14. The method as claimed in claim 1, wherein the corresponding portion of the electronically-accessible resources is a spatially localized extent of the resources.

15. The method as claimed in claim 1, wherein the corresponding portion of the electronically-accessible resources is a temporally localized extent of the resources.

16. An apparatus for browsing electronically-accessible resources using descriptions of the resources, said apparatus comprising:

a processor;

means for generating descriptions of the electronically-accessible resources, the generated descriptions being separate from the content of the resources and comprising descriptor components classified as either table-of-contents descriptor components or index descriptor components, each said table-of-contents descriptor component having a link to a corresponding portion of the electronically-accessible resources;

means for displaying items for selection, each displayed item corresponding to a table-of-contents descriptor component of a generated description;

means for receiving a selection of one or more of said displayed items;

means for displaying further items for selection, the further items corresponding to index descriptor components that are associated with the one or more table-of-contents descriptor components corresponding to the selected one or more of said displayed items;

means for receiving a selection of one of said displayed further items;

means for providing a representative value associated with said selected further item;

means for forming a query from the index descriptor component corresponding to said selected one of said displayed further items and said provided representative value;

means for searching said generated descriptions to return one or more table-of-contents descriptor components that satisfy said query and are contained in the one or more table-of-contents descriptor components corresponding to the selected one or more of said displayed items; and

means for displaying for selection one or more still further items corresponding to said returned one or more table-of-contents descriptor components.

17. The apparatus as claimed in claim 16, wherein said means for generating the descriptions represents each description in a tree of descriptor components, and one or more of the descriptor components have descriptor components as descendants.

18. The apparatus as claimed in claim 16, further comprising viewing means for viewing, in response to a selection of one of said still further displayed items, the portion of the electronically-accessible resources corresponding to a returned table-of-contents descriptor component linked to by the selected one of said still further displayed item.

19. The apparatus as claimed in claim 16, wherein the descriptions of the electronically-accessible resources are provided using a description scheme as a template, and the description scheme uses a declarative description definition language which contains definitions for descriptor components of the descriptions of the resources.

20. The apparatus as claimed in claim 19, wherein the attributes of the descriptor components are defined in the description scheme.

21. The apparatus as claimed in claim 19, wherein the attributes of the descriptor components are persistent items of the description scheme.

22. The apparatus as claimed in claim 19, wherein the attributes of the descriptor components are instantiated by an application when required.

23. The apparatus as claimed in claim 22, wherein the attributes of the descriptor components are instantiated using a rule that is associated with the description scheme.

24. The apparatus as claimed in claim 16, wherein the electronically-accessible resources comprise digital audiovisual content.

25. The apparatus as claimed in claim 16, wherein the electronically-accessible resources comprise an electronic document or resource available over the World Wide Web.

26. The apparatus as claimed in claim 16, wherein the electronically-accessible resources comprise information about an electronic device.

27. The apparatus as claimed in claim 16, wherein a descriptor component is classified to be a table-of-contents descriptor if the descriptor component contains a reference to a resource or a section of a resource.

28. The apparatus as claimed in claim 27, wherein a descriptor component is classified to be an index descriptor if the descriptor component is not classified to be a table-of-contents descriptor.

29. A computer storage medium, having a computer program recorded thereon, where the program is executable to perform a procedure for browsing electronically-accessible resources using descriptions of the resources, said computer program comprising:
