TL;DR
This paper introduces the Parameter Description Language (PDL) as an XML-based, expressive data model for describing web service parameters and constraints, aiming to enhance interoperability.
Contribution
It defines a rigorous, self-descriptive language for web service parameters, facilitating semantic understanding and complex constraint representation.
Findings
PDL provides a formal data model for parameters.
PDL enhances web service interoperability.
PDL supports complex parameter constraints.
Abstract
This document discusses the definition of the Parameter Description Language (PDL). In this language parameters are described in a rigorous data model. With no loss of generality, we will represent this data model using XML. It intends to be a expressive language for self-descriptive web services exposing the semantic nature of input and output parameters, as well as all necessary complex constraints. PDL is a step forward towards true web services interoperability.
