1. A system for creating a data structure comprising:
- an input configured to receive at least first and second ink strokes;
a processor configured to parse the received ink strokes and to determine at least a first and a second property associated with the ink strokes; and
a storage configured to store the ink strokes in a data structure with at least one tag identifying and delimiting data associated with said at least first and second property, thereby allowing said system to ignore data not understood,the data structure further including a portion containing index data associated with said at least first and second property of the handwritten ink information, the tag data having 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 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.

Abstract
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.

4. A system for using a data structure comprising:
-
a storage configured to store first and second ink strokes in a data structure with at least one tag identifying at least a first and a second property, the data structure including a portion containing index data associated with said at least first and second property of the handwritten ink information, the tag data having a reference to the index data; and
,a processor configured to retrieve the ink strokes and said at least one tag and apply said first property of the handwritten ink information associated with the index data to the tag data and the first ink stroke based on the reference and apply the second property of the handwritten ink information associated with the index data to the tag data and the second ink stroke based on the reference when rendering said ink strokes, 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.
