The Chinese character description languages are several proposed languages to most accurately and completely describe Chinese (or CJK) characters and information such as their list of components, list of strokes (basic and complex), their order, and the location of each of them on a background empty square. They are designed to overcome the inherent lack of information within a bitmap description. This enriched information can be used to identify variants of characters that are unified into one code point by Unicode and ISO/IEC 10646, as well as to provide an alternative form of representation for rare characters that do not yet have a standardized encoding in Unicode or ISO/IEC 10646. Many aim to work for Kaishu style and Song style, as well as to provide the character's internal structure which can be used for easier look-up of a character by indexing the character's internal make-up and cross-referencing among similar characters. CDL Character Description Language is a font technology, based on XML, co-created by Tom Bishop and Richard Cook for Wenlin Institute, Inc, designed for describing any CJK character, but suitable for describing any glyph. This XML-based declarative language defines the stroke order of each component (a subunit of the glyph similar to a radical, but not necessarily bearing the semantic significance of a true radical), as well as assembly of previously defined components to build up ever more complex characters. Many of these components are characters in their own right, in addition to serving as building-block components. The background looks like a square of 128 pixels on each side. In this background: Each of about 50 strokes can be drawn in SVG. A basic component is composed by calling several strokes. In this component, each stroke is described by its bottom-left and top-right corner. Transformations are possible (reduction, enlargement, etc.). There are more than 1,000 basic components. A character is composed by calling several components. In this character, each component is described by its bottom-left and top-right corner. In order for a component to fit into its proper portion of the Chinese character's rectangular block, a component may be transformed (e.g., horizontal or vertical reduction or enlargement) upon its use as a building-block embedded within a containing more-complex character. Accordingly, a set of less than 50 strokes allow one to construct a set of about 1,000 components which may in turn be embedded within tens of thousands of characters' descriptions.
