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 computer-readable medium having a data structure thereon for storing an ink object, said data structure being read and processed by a computer, said data structure relating to storing a first stroke and at least a second stroke of handwritten ink information, said information including at least one tag delimiting tag data, where at least some of said handwritten ink information is not recognized by said computer, said data structure comprising: a first portion having an ink object identifier, said ink object identifier indicating a type of ink object; a second portion identifying a size of said tag data, said size permitting said computer to skip over said tag data when said computer does not recognize said tag data; a third portion having index data associated with a first property and a second property of the handwritten ink information; and a fourth portion having said tag data in said ink object, the tag data including a reference to the index data, wherein the first property of the handwritten ink information associated with the index data is applied to the tag data and the first 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 stroke based on the reference, the property comprising 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 computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion relating to a version of the ink object. 3. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing global properties. 4. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing a global unique identifier. 5. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing an ink space rectangle. 6. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing drawing attributes. 7. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing stroke descriptors. 8. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing metrics. 9. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing the compression used. 10. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing local properties. 11. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing a drawing attribute index. 12. The computer readable medium according to claim 1, wherein said data structure is encoded. 13. The computer readable medium according to claim 1, wherein said data structure further comprises a fifth portion describing predefined and custom GUIDs.
