Ink is stored in a data structure that permits later retrieval by applications. The ink includes stroke information and property information. Properties may be associated globally with the ink strokes and/or with each stroke individually. Aspects include a data structure that supports ink for multiple applications. Using the storage system, method, and data structure, various applications may expand on ink to include additional attributes while permitting the ink to be used in applications not supporting the additional attributes. When encountering an unknown tag, the applications will skip past the end of the tag and its associated data to start reading the next tag.

The invention claimed is: 1. A method for using a data structure for storing ink, said data structure being read and processed by a computer, said data structure relating to storing at least a first ink stroke and a second ink stroke of handwritten ink information, comprising the steps of: identify
The invention claimed is: 1. A method for using a data structure for storing ink, said data structure being read and processed by a computer, said data structure relating to storing at least a first ink stroke and a second ink stroke of handwritten ink information, comprising the steps of: identifying a tag in the data structure, said tag delimiting data associated with the tag and including a reference to index data associated with a first property of the first ink stroke and a second property of the second ink stroke of the handwritten ink information; retrieving a size of the data associated with the tag; and if an application recognizes the tag, then reading the data associated with the tag, otherwise skipping the tag by skipping past the data based on the size of the data, wherein the first property of the handwritten ink information associated with the index data is applied to the tag data and the first ink stroke based on the reference and the second property of the handwritten ink information associated with the index data is applied to the tag data and the second ink stroke based on the reference, and wherein the properties include at least one of a specific color, line width, drawing attribute, count of points, stroke size, a shape of pen tip, a type of pen tip, a point at which a stylus starts a stroke, stroke coordinates, pressure, angle of pen, and interval of time between coordinates. 2. The method according to claim 1, further comprising the steps of: retrieving a version number of said tag; if said application is compatible with said version of the tag, then reading the data associated with the tag, otherwise skipping the tag by skipping past the data based on the size of the data. 3. The method according to claim 1, further comprising the steps of: retrieving information relating to a global unique identifier used within the data of said tag; if said application is compatible with said global unique identifier, then reading the data associated with the tag, otherwise skipping the tag by skipping past the data based on the size of the data. 4. The method according to claim 1, wherein said data includes metric information. 5. The method according to claim 4, wherein said reading step includes determining if said metric information is compatible with said application. 6. The method according to claim 1, wherein said data includes GUID information. 7. The method according to claim 6, wherein said reading step includes determining if said GUID information is compatible with said application. 8. The method according to claim 1, wherein said data includes drawing attribute information. 9. The method according to claim 8, wherein said reading step includes determining if said drawing attribute information is compatible with said application. 10. The method according to claim 1, wherein said data includes stroke descriptor information. 11. The method according to claim 10, wherein said reading step includes determining if said stroke descriptor information is compatible with said application. 12. The method according to claim 1, wherein said data includes ink space mapping information. 13. The method according to claim 12, wherein said reading step includes determining if said ink space mapping information is compatible with said application. 14. The method according to claim 1, wherein said data includes compression information. 15. The method according to claim 14, wherein said reading step includes determining if said compression information is compatible with said application. 16. The method according to claim 3, wherein said data includes compression information. 17. The method according to claim 16, wherein said reading step includes determining if said compression information is compatible with said application. 18. The method according to claim 1, wherein said data includes custom property information. 19. The method according to claim 18, wherein said reading step includes determining if said custom property information is compatible with said application.
