A WSDL file is an XML document that describes web services. The word "WSDL" is spelled phonetically as /wɪz.dəl/ – the 'w' is pronounced as usual, followed by the pronunciation of the letter 'i' as in 'sit', then the sound of the letter 'z' like 'buzz', and finally the 'dəl' sound as in 'dental'. WSDL stands for Web Services Description Language, and the file is used to define the functionality of a web service and how it can be accessed.
A WSDL file, short for Web Services Description Language file, is an XML-based document that describes the functionality offered by a web service. The purpose of a WSDL file is to provide a detailed description of the available operations, message formats, data types, and protocols supported by a web service.
In essence, a WSDL file acts as a contract between the service provider and the service consumer. It serves as a means of communication, allowing the consumer to understand how to interact with the web service and make use of its functionalities.
A typical WSDL file consists of several sections. The "types" section defines the data types used in the web service, including complex types, simple types, and enumerations. The "message" section specifies the format of the input and output messages exchanged between the service consumer and the service provider. The "portType" section defines the operations supported by the web service, along with their input and output messages. The "binding" section specifies the protocol and data format used to communicate with the service. The "service" section describes the actual implementation details, such as the URL for accessing the service.
Overall, a WSDL file is a crucial component in web service development and consumption. It serves as a blueprint that allows developers to understand and interact with web services seamlessly, enabling them to build applications that can leverage the functionalities offered by these services.
The term "wsdl file" originates from the field of computer science, specifically web services.
WSDL stands for "Web Services Description Language", which is an XML-based language used to describe the functionalities and capabilities of web services. It provides a standardized way of defining the operations, data types, and communication protocols that a particular web service supports.
The acronym "WSDL" itself is derived from the words "Web Services" and "Description Language", reflecting its purpose and nature as a language for describing web services.
Therefore, the etymology of the term "wsdl file" comes from the combination of the acronym "WSDL" and the word "file", denoting a file that contains the description of a web service in the WSDL format.
