Abstract

In an example embodiment, a method is provided for linking an annotation to a document object of a document. Here, a structured document format associated with the document is accessed and this structured document format defines document objects and object identifiers identifying the document objects. The annotation assigned to the document object is received and an object identifier that identifies the document object is identified. This object identifier comprises at least one other document object that is related to the document object. The object identifier is then associated with the annotation and this association links the annotation to the document object.

Claims

1. A method of linking an annotation to a document object associated with a document, the method comprising:

accessing a structured document format associated with the document, the structured document format defining a plurality of document objects and a plurality of object identifiers identifying the plurality of document objects;

receiving the annotation assigned to the document object in the plurality of document objects;

identifying an object identifier in the plurality of object identifiers that identifies the document object, the object identifier comprising at least one of the plurality of document objects that is related to the document object; and

associating the object identifier with the annotation, the association linking the annotation to the document object.

2. The method of claim 1, further comprising storing the annotation with the object identifier.

3. The method of claim 1, wherein the structured document format further defines a first position associated with the document object, the method further comprising:

calculating a second position of the annotation that is relative to the first position; and

associating the second position with the object identifier.

4. The method of claim 3, further comprising storing the second position with the annotation and the object identifier.

5. The method of claim 1, wherein the structured document format is a document object model.

6. The method of claim 1, wherein the plurality of document objects is organized following a hierarchical structure, and wherein the at least one of the plurality of document objects is an ascendant of the document object.

7. The method of claim 1, wherein the at least one of the plurality of document objects that is related to the document object is text.

8. The method of claim 1, wherein the at least one of the plurality of document objects that is related to the document object is a numerical value.

9. The method of claim 1, wherein the structured document format is accessed from a presentation module, the presentation module configured to render at least a portion of the plurality of document objects.

10. The method of claim 1, wherein the document cannot be modified from the presentation module.

11. A processing system comprising:

at least one processor; and

a memory in communication with the at least one processor, the memory being configured to store a presentation module and a synchronization module that are executable by the at least one processor,

the presentation module having instructions, that when executed by the at least one processor, cause operations to be performed, comprising;

accessing a document;

converting the document into a document object model, the document object model defining a plurality of document objects; and

generating an object identifier identifying at least one of the plurality of document objects, the object identifier comprising at least another one of

the plurality of document objects that is an ascendant of the at least one of

the plurality of document objects associated with the object identifier,

the synchronization module having instructions, that when executed by the at least one processor, cause operations to be performed, comprising;

receiving an annotation assigned to the at least one of the plurality of document objects; and

associating the object identifier with the annotation.

12. The processing system of claim 11, wherein the operation of generating the plurality of document objects comprises:

identifying the at least another one of the plurality of document objects that is the ascendant of the at least one of the plurality of document objects; and

appending the at least another one of the plurality of document objects to the object identifier.

13. The processing system of claim 11, wherein the synchronization module having instructions, that when executed by the at least one processor, cause operations to be performed, further comprising:

receiving a relative position of the annotation, the relative position being relative to a position of the at least one of the plurality of document objects; and

associating the relative position with the object identifier.

14. The processing system of claim 11, wherein the memory is configured to store an annotation module that is executable by the at least one processor, wherein the presentation module does not expose an application programming interface to the annotation module.

15. The processing system of claim 11, wherein the presentation module is a document viewer.

16. The processing system of claim 11, wherein the document cannot be modified from the annotation module.

17. The processing system of claim 11, wherein the document object model is a HyperText Markup Language (HTML) document object model.

18. The processing system of claim 11, wherein the document object model is an Extensible Markup Language (XML) document object model.

19. A method of positioning an annotation associated with a document object, the method comprising:

accessing a structured document format associated with a document, the structured document format defining a plurality of document objects, a plurality of object identifiers identifying the plurality of document objects, and a plurality of positions of the plurality of document objects in the document;

accessing the annotation and an object identifier assigned to the annotation;

comparing the object identifier with at least one of the plurality of object identifiers defined in the structured document format to identify a match of the object identifier with the at least one of the plurality of object identifiers;

accessing a position of the document object in the plurality of document objects based on the match; and

positioning the annotation based on the position of the document object.

20. The method of claim 19, further comprising updating the positioning of the annotation based on a refresh of the document.

21. The method of claim 19, further comprising repositioning the annotation based on a change in the position of the document object.

22. The method of claim 19, wherein the object identifier comprises at least another one of the plurality of document objects that is related to the document object.

23. The method of claim 19, further comprising accessing a relative position of the annotation, the relative position being relative to the position of the document object, wherein the positioning of the annotation is further based on the relative position.

24. A machine-readable medium that stores instructions, which when performed by a machine, cause the machine to perform operations comprising:

accessing a document;

converting the document into a document object model, the document object model comprising a plurality of document objects;

identifying at least one of the plurality of document objects associated with an annotation added to the document;

identifying at least another one of the plurality of document objects that is an ascendant of the at least one of the plurality of document objects; and

generating an object identifier identifying the at least one of the plurality of document objects based on the at least another one of the plurality of document objects, the object identifier configured to be associated with the annotation.
