van Fraassen, Bas C. (2016) [1971]. Formal Semantics and Logic (PDF). Nousoul Digital Publishers. p. 12. Metalogic can in turn be roughly divided into two parts: proof theory and formal semantics... The division is not exact; many questions have been dealt with from both points of view, and some proof-theoretic methods and results are indispensable in semantics.

Rulifson, Johns F. (April 1968). "A Tree Meta for the XDS 940" (PDF). Augmentation Research Center. Retrieved 30 November 2024. There are two classes of formal-language definition compiler-writing schemes. The productive grammar approach is the most common. A productive grammar consists primarrly of a set of rules that describe a method of generating all possible strings of the language. The reductive or analytical grammar technique states a set of rules that describe a method of analyzing any string of characters and deciding whether that string is in the language.
