A Concept Representation Language (CRL)

Formal languages, each with its own syntax and semantics, enable precise communications within specific domains. However, in model-based engineering and data fusion, no single language provides a comprehensive description: multiple formal languages are required, and these must be precisely related to one another. This begs the questions as to what formal language can be used to express the relationships between the elements of two or more formal languages? There is almost a total lack of such languages and, in their absence, most relationships are expressed procedurally with code that is specific to the referenced languages. This paper introduces a Concept Representation Language, capable of uniformly representing concepts and relationships at all levels of abstraction. The paper covers the motivation, design principles, and infrastructure provided by the language.
