Abstract
Digital ink annotations of digital documents are captured, processed, and stored for later retrieval. Elements within the digital documents are found and data concerning them are stored, in order that they may be associated with the digital ink annotation and serve as anchors for the digital ink annotations within the digital documents being annotated. Furthermore, a markup language schema is used for the efficient, standardized storage of the digital ink annotations. By these means, digital ink annotations are stored efficiently, retrieved, and rendered accurately across different types of browsers and operating systems, as well as across different size browser windows and output devices.
