Frame language
Appearance
Frame language is a meta-language. It applies the frame concept to the structuring of language properties.
Frame languages are usually software languages. In general, "frame" means "something what can/(has to) be fulfil". In such sense, for example: object-oriented languages are frame languages, but also every grammar is a frame language. In specific contexts, the authors of computer languages use the term "frame" arbitrarily and frequently intuitively, and in a metaphoric sense. Frame languages are rather focused on the recognition and description of objects classes, and relations and interactions are considered as "secondary".
