The W3C Multimodal Interaction working group has posted the second public working draft of EMMA: Extensible MultiModal Annotation markup language. According to the abstract, "This document is part of a set of specifications for multi-modal systems, and provides details of an XML markup language for describing the interpretation of user input. Examples of interpretation of user input are a transcription into words of a raw signal, for instance derived from a speech or pen input, a set of attribute/value pairs describing their meaning, or a set of attribute/value pairs describing a gesture. The interpretation of the user's input is expected to be generated by signal interpretation processes, such as speech and ink recognition, semantic interpreters, and other types of processors for use by components that act on the user's inputs such as interaction managers."
