International audienceChoreographies allow designers to specify the protocols followed by participants of a distributed interaction. In this context, adaptation may be necessary to respond to external requests or to better suit a changing environment (a self-update). Adapting the behavior of a participant requires to update in a coordinated way possibly all the participants interacting with him. We propose a language able to describe a choreography together with its adaptation strategies, and we discuss the main issues that have to be solved to enable adaptation on a participant code dealing with many interleaved protocols
