Plain language

One method to satisfy checkpoint 4.1 is to use a "controlled language" or a reduced word vocabulary. Many industries have controlled languages. For example the aerospace industry uses controlled languages to write technical manuals. Avi Arditti selected the following resources for introduction to this topic.

Concept codes

The WWAAC has been working on the idea of standardizing concept codes to facilitate translation of text into symbols. Lisa Seeman is also interested in this and has produced an example schema.

W3C Annotea work

If text was annotated with concept codes, then a browser could request the annotations (concept codes) for a web page display the appropriate symbols instead of or alongside text. The Annotea project is W3C work to create an annotation client (in Amaya) and methods to store and retrieve annotations.
