Abstract

Methods and apparatus are provided for supporting text-based context links for application programs. In some embodiments, an application executing on a first computer system may receive a request to open a context link to a text element in a document. The application may determine, based on a list of context links, whether more than one data object is associated with the text element. If so, a list of data objects associated with the text element and distinguishing information may be displayed, a selection of a data object from the displayed list may be received, and a selection of an action relating to a context link for the selected data object may be received. In some embodiments, the context link list is created by parsing a document into text elements at the first computer, storing entries representing a plurality of text elements on a list, and transmitting the list to a second computer to determine in the second computer if the text elements are associated with data objects. In some embodiments, before transmitting a data element to a second computer to determine an association with a data object, a software cache is checked to determine if the text element has already been transmitted, with text elements removed from the software cache if the software cache is larger than a threshold amount.

Claims

1. A method comprising:

receiving at an application program executing on a computer system a request to open a context link to a text element that is part of a document being operated on by the application program;

determining whether more than one data object of a data object type is associated with the text element and, if so, performing the following;

displaying a list of data objects of that data object type that are associated with the text element;

displaying information to distinguish listed data objects;

receiving a selection of a data object from the displayed list; and

receiving a selection from a list of actions relating to a context link for the selected data object.

2. The method of claim 1, wherein the method further comprises recording that the selected data object is a default data object for future requests to open a context link to that text element.

3. The method of claim 1, wherein the method further comprises:

determining that an additional text element has been entered into the document;

determining that the additional text element is associated with more than one data object of a data object type; and

creating a context link from the additional text element to each of the associated data objects.

4. The method of claim 3, wherein said creating a context link comprises creating an entry for the text element in a list, wherein said entry records information to distinguish a data object associated with the text element from other data objects that are associated with the text element.

5. The method of claim 1, wherein all context links are supported by a single dynamic link library file.

6. A method comprising:

parsing a new document being operated on by an application program at a first computer into text elements;

storing an entry on a first list for each of a plurality of the text elements, wherein each entry represents a text element;

transmitting the first list from the first computer to a second computer to determine in the second computer if the text elements represented on the first list are associated with data objects in the second computer;

receiving an indication at the first computer from the second computer whether text elements represented on the first list were determined to be associated with a data object; and

creating an entry in a context link list at the first computer for each of the text elements that were determined to be associated with a data object, wherein entries on the context link list indicate that a text element is associated with at least one data object as a context link.

7. The method of claim 6, wherein the method further comprises determining if a representative of all the text elements in the document has been transmitted to the second computer and, if not, repeating said transmitting, receiving and creating until representatives of all the text elements in the document have been transmitted to the second computer.

8. The method of claim 6, wherein the first list that is transmitted does not contain more than one entry that represents an instance of any particular text element.

9. The method of claim 6, wherein at least one entry in the context link list associates a text element with more than one data object.

10. The method of claim 6, wherein said storing an entry on a first list for each of the plurality of text elements comprises:

determining for each of the plurality of text elements whether the text elements are represented in a software cache, wherein each text element that is represented in the software cache was previously transmitted to the second computer for determining if the text element is associated with a data object; and

storing a text element on the first list of text elements only if that text element was not found to be represented in the software cache.

11. The method of claim 10, wherein said transmitting the first list further comprises adding entries to the software cache for the text elements represented on the first list.

12. The method of claim 11, wherein said transmitting the first list further comprises determining whether the size of the software cache is greater than a threshold amount and, if so, removing entries from the software cache.

13. The method of claim 12, wherein removing entries from the software cache further comprises removing a plurality of entries for least recently used text elements from the software cache.

14. The method of claim 13, wherein removing entries from the software cache further comprises removing entries from the software cache that have been in the software cache for more than a threshold amount of time.

15. The method of claim 6, further comprising:

receiving at the application program a request to open a context link to a text element;

determining whether more than one data object of a data object type is associated with the text element and, if so, performing the following;

displaying a list of data objects of the data object type that are associated with the text element;

displaying information to distinguish the listed data objects from each other;

receiving a selection of a data object from the displayed list;

receiving a selection of an action relating to a context link for the selected data object for one of the listed actions; and

transmitting a request from the first computer to the second computer to perform an action on the selected data object.

16. A method comprising:

parsing a new document being operated on by an application program at a first computer into text elements;

determining if a text element is represented in a software cache, wherein the text elements represented in the software cache were previously transmitted to a second computer for determining if those text elements are associated with a data object;

if the text element is not represented in the software cache, performing the following;

transmitting a representative of the text element from the first computer to the second computer to determine in the second computer if the text element is associated with one or more data objects;

determining whether the size of software cache is greater than a threshold amount and, if so, removing entries from the software cache;

adding the transmitted text element to the software cache; and

receiving a response at the first computer from the second computer that indicates whether the transmitted text element was determined to be associated with a data object and, if so, creating an entry in a context link list at the first computer to indicate that the text element is associated with at least one data object as a context link.

17. The method of claim 16, wherein removing entries from the software cache comprises removing a plurality of entries for least recently used text elements from software cache.

18. The method of claim 16, wherein removing entries from the software cache further comprises removing entries from the software cache that have been in the software cache for more than a threshold amount of time.

19. The method of claim 16, wherein said transmitting a representative of the text element from the first computer to the second computer comprises transmitting a list representing that text element and a plurality of other text elements to the second computer to determine in the second computer if the text elements are associated with data objects.

20. The method of claim 16, further comprising:

receiving a request to open a context link to a selected text element;

determining whether more than one data object of a data object type corresponds to the selected text element and, if so, performing the following;

displaying a list of data objects of the data object type that are associated with the selected text element;

displaying information to distinguish listed data objects;

receiving a selection of a data object from the displayed list;

receiving a selection of an action relating to a context link for the selected data object; and

transmitting a request from the first computer to a second computer to perform the selected action on the selected data object.
