WS-CDL

The Web Services Choreography Description Language (WS-CDL) was a specification by W3C of a language that describes a choreography.

The members of the Working Group described it as follows:

The Web Services Choreography Description Language (WS-CDL) is an XML-based language that describes peer-to-peer collaborations of participants by defining, from a global viewpoint, their common and complementary observable behavior; where ordered message exchanges result in accomplishing a common business goal.

The effort to standardize WS-CDL was abandoned in 2009, leaving v1.0 as a 'candidate recommendation' only.

The WS-CDL is of interest to the PL community, because the Working Group invited many PL experts from academia to contribute to the effort (including Robin Milner, Kohei Honda, Nobuko Yoshida, and Marco Carbone).
