Web Services Description Language

The Web Services Description Language (WSDL /ˈwɪz dəl/) is an XML-based interface definition language that is used for describing the functionality offered by a web service.

Description

The acronym is also used for any specific WSDL description of a web service (also referred to as a WSDL file), which provides a machine-readable description of how the service can be called, what parameters it expects, and what data structures it returns.

It thus serves a purpose that corresponds roughly to that of a method signature in a programming language.
