This paper focuses on the interpretation of metaphor in discourse. We build on previous work (Agerri, Barnden, Lee, & Wallington, 2007) to offer a formalization in a computationally-oriented formal semantic framework of a set of mappings that we claim are required for the interpretation of map-transcending metaphor. Such mappings are domain-independent and are identified as invariant adjuncts to

More-over, these mappings interact with rhetorical relations in order to explain cases in which recognizing their structure is not sufficient to provide an interpretation of a metaphorical discourse.
