       This paper presents an approach to support choreography in
       agricultural supply chains. It depicts a model for this kind of
       chain that considers both static and dynamic aspects, and their
       mapping to an underlying architecture. In particular, the model
       emphasizes mutual agreements, coordination of activities,
       quality enforcement and activity documentation. The
       architecture is centered on mapping chain elements to Web
       Services and their dynamics to the choreography of services. A
       case study, for soy supply chains, is used to motivate the
       approach.
