Towards a strategy language for Maude Narciso Marti-Oliet (joint work with Jose Meseguer and Alberto Verdejo) We describe a proposal for a strategy language for Maude, to control the rewriting process and to be used at the object level instead of at the metalevel. We also describe a prototype implementation built over Full Maude using the metalevel and the metalanguage facilities provided by Maude. We include a series of examples that illustrate the main features of the proposed strategy language. This language has been put to work in the implementation of operational semantics for the ambient calculus and for the parallel functional language Eden. Related papers: N. Marti-Oliet, J.
