The Dialogue Game Description Language (DGDL)

The Dialogue Game Description Language (DGDL) is a domain specific language for describing dialectical games. The latest version DGDL+ is an extended, refined and simplified, implementation of the original DGDL specification described in “A domain specific language for describing diverse systems of dialogue” (Wells & Reed, Journal of Applied Logic, 10 (4), pp 309–329).

The DGDL+ specification and several example dialogue games in DGDL+ can be downloaded below.
