The Operative Field is a disciplinary map by Lee Sharks of fields that study signs producing effects.
It includes speech-act theory, Peircean semiosis, document theory, rhetoric, platform studies, metadata engineering, prompt engineering, computational law, training-layer literature, and operative philology.
Each field is compared by the object that acts, substrate, target, mechanism, and effect on a shared meaning commons.
The paper does not claim these disciplines are subdivisions of operative semiotics. It proposes one comparative framework for their overlapping concern with signs that intervene.
