'''SDL''' (short for '''S'''pecification and '''D'''escription '''L'''anguage) is an [[specification language]] targeted at the unambiguous specification and description of the behaviour of reactive and distributed systems. It is defined by the [[ITU-T]] (Recommendation Z100Z.100.) Originally focused on telecommunication systems, its current areas of application include process control and real-time applications in general.

SDL provides both a graphical ''Graphic Representation'' (SDL/GR) as well as a textual ''Phrase Representation'' (SDL/PR), which are both equivalent representations of the same underlying semantics. A system is specified as a set of interconnected abstract machines which are extensions of [[finite state machine]]s (FSM).
