InkML supports a complete and accurate representation of digital ink.
In addition to the pen position over time, InkML allows recording of information about device characteristics and detailed dynamic behavior to support applications such as handwriting recognition and authentication. For example, there is support to record additional information such as pen tilt and pen tip force (often referred to as "pressure") and information about the recording device such as accuracy and dynamic distortion. InkML also provides features to support rendering of digital ink captured optically to approximate the original appearance. For example, stroke width and color information can be recorded.
InkML provides means for extension. By virtue of being an XML-based language, users may easily add application-specific information to ink files to suit the needs of the application at hand.
