We show how software development based on algebraic specification can formally be represented in the development language Deva. We have formalized essential parts of the algebraic specification language Spectrum and a semantic development relation. The use of such a representation is three-fold: It makes developments amenable to consistency checks by machine, it documents the development for human readers, and it makes explicit the correspondence of development steps and resulting proof obligations.
