This document discusses the definition of the Parameter Description Language (PDL). In this language sentences and syntactical elements are organized into a rigorous data model. With no loss of generality, we will represent this data model using XML. It intends to be a description language for self-descriptive web services exposing the semantic nature of input and output parameters, as well as all possible complex con- straints. PDL is a step forward towards web services interoperability.
