Abstract

Methods and systems allow style and other formatting settings to remain latent until one or more particular style or formatting settings is instantiated by a user. Data representing each latent style or formatting object is persisted in a data structure apart from the user'"'"'s document. Each potential style setting or formatting setting may be set as locked for use for a given document or locked for non-use for a given document. Upon saving the document, no data is saved for the numerous available style and formatting settings in the document. When a particular style is called upon by a subsequent consuming application, that application may then instantiate the particular style or formatting setting based on the properties of that style or formatting setting available from the subsequent consuming application.

Claims

1. A method of representing formatting functionality available to an application program for applying to a document, comprising:

saving a document as an Extensible Markup Language (XML) representation whereby XML markup is applied to the document to represent text and data objects, properties and attributes including formatting styles applied to the document;

enumerating all formatting styles available to the document according to functionality of an application program creating or editing the document;

setting a default designation for the enumerated formatting styles as locked for use or locked for non-use;

for any of the enumerated formatting styles that may be used or that may not be used in contradiction to the default designation for all enumerated formatting styles, designating said any of the enumerated formatting styles as an exception to the default designation; and

saving data identifying the enumerated formatting styles, identifying the default designation, and identifying any exceptions to the default designation to a data structure separate from the document;

wherein when the default designation is set as locked for non-use, the any exceptions comprise a minority of the enumerated formatting styles and are available for use; and

wherein when the default designation is set as locked for use, the any exceptions comprise a minority of the enumerated formatting styles and are not available for use.

2. The method of claim 1, further comprising applying an XML markup to the document representing a count of the enumerated formatting styles, representing the default designation for the enumerated formatting styles, and representing formatting styles that are designated as exceptions to the default designation.

3. The method of claim 2, further comprising applying an XML markup to the document representing a pointer to the data structure.

4. The method of claim 3, further comprising:

opening the document by a subsequent consuming application;

parsing the document for XML markup representing a count of the enumerated formatting styles, representing the default designation for the enumerated formatting styles, and representing formatting styles that are designated as exceptions to the default designation; and

parsing the document for a pointer to the data structure for determining formatting styles enumerated for the document.

5. The method of claim 4, further comprising determining the default designation for the enumerated formatting styles.

6. The method of claim 5, further comprising determining whether any exceptions to the default designation are designated for the document.

7. The method of claim 6, whereby if a desired formatting style is available for use, instantiating the formatting style by the consuming application according to formatting functionality available to the consuming application associated with the desired formatting style.

8. The method of claim 7, further comprising formatting the document with the instantiated formatting style.

9. A computer program product comprising a computer-readable medium having control logic stored therein for causing a computer to represent formatting functionality available to an application program for applying to a document, the control logic comprising computer-readable program code for causing the computer to:

save a document as an Extensible Markup Language (XML) representation whereby XML markup is applied to the document to represent text and data objects, properties and attributes including formatting styles applied to the document;

enumerate all formatting styles available to the document according to functionality of an application program creating or editing the document;

setting a default designation for the enumerated formatting styles as locked for use or locked for non-use;

for any of the enumerated formatting styles that may be used or that may not be used in contradiction to the default designation for all enumerated formatting styles, designate said any of the enumerated formatting styles as an exception to the default designation; and

save data identifying the enumerated formatting styles, identifying the default designation, and identifying any exceptions to the default designation to a data structure separate from the document;

wherein when the default designation is set as locked for non-use, the any exceptions comprise a minority of the enumerated formatting styles and are available for use; and

wherein when the default designation is set as locked for use, the any exceptions comprise a minority of the enumerated formatting styles and are not available for use.

10. The computer program product of claim 9, further comprising computer-readable program code for causing the computer to apply an XML markup to the document representing a count of the enumerated formatting styles, represent the default designation for the enumerated formatting styles, and represent formatting styles that are designated as exceptions to the default designation.

11. The computer program product of claim 10, further comprising computer-readable program code for causing the computer to apply an XML markup to the document representing a pointer to the data structure.

12. The computer program product of claim 11, further comprising computer-readable program code for causing the computer to:

open the document by a subsequent consuming application;

parse the document for XML markup representing a count of the enumerated formatting styles, represent the default designation for the enumerated formatting styles, and represent formatting styles that are designated as exceptions to the default designation; and

parse the document for a pointer to the data structure for determining formatting styles enumerated for the document.

13. The computer program product of claim 12, further comprising computer-readable program code for causing the computer to determine the default designation for the enumerated formatting styles.

14. The computer program product of claim 13, further comprising computer-readable program code for causing the computer to determine whether any exceptions to the default designation are designated for the document.

15. The computer program product of claim 14, further comprising computer-readable program code for causing the computer to instantiate a desired formatting style by the consuming application according to formatting functionality available to the consuming application associated with the desired formatting style when the desired formatting style is available for use.

16. The computer program product of claim 15, further comprising computer-readable program code for causing the computer to format the document with the instantiated formatting style.
