SalesForce to integrate with external RESTful service

Question

Being new to SalesForce Integration, I am trying to understand the capability of SalesForce to integrate with external RESTful service (WADL file) and execute to extract data to use in SalesForce UI functionality.

I understand that SalesForce is able to execute SOAP over HTTP (WSDL file) service to integrate but I see there is no solid documents online to explore whether SalesForce can also execute external WADL file.

Please advice me.

There's no built in feature to consume a WADL. You can however, just write your own Apex code to make restful callouts.
