Content Dictionary

A formal specification in the OpenMath standard that provides the definition, description, and properties of a collection of related mathematical symbols. Each Content Dictionary defines symbols used in a particular mathematical domain (such as arithmetic, linear algebra, or calculus) along with their formal mathematical properties, plain-text descriptions, and encoded examples. In accessibility applications, Content Dictionaries enable assistive technologies to generate meaningful spoken descriptions of mathematical symbols and to provide contextual information during aural navigation of mathematical expressions.
