• Modal Specifications with Data (MSDs) as a specification formalism.
• A specification theory with explicit data for possibly infinite-domain variables.
• A modal specification theory with parallel composition, conjunction and quotient.
• A modal specification theory with refinement, consistency and pruning.
• A symbolic predicate-based representation of our formalism.
Modal specification is a well-known formalism used as an abstraction theory for transition systems. Modal specifications are transition systems equipped with two types of transitions: must-transitions that are mandatory to any implementation, and may-transitions that are optional. The duality of transitions allows for developing a unique approach for both logical and structural compositions, and eases the step-wise refinement process for building implementations. We propose Modal Specifications with Data (MSDs), the first modal specification theory with explicit representation of data. Our new theory includes the most commonly seen ingredients of a specification theory; that is parallel composition, conjunction and quotient. As MSDs are by nature potentially infinite-state systems, we propose symbolic representations based on effective predicates. Our theory serves as a new abstraction-based formalism for transition systems with data.
