A method of automatically consuming and processing web services includes parsing a first document describing a web service to identify a first set of attribute-value pairs describing a function offered by the web service and a second set of attribute-value pairs specifying instructions for processing result data returned by the function for rendering in a user interface element; constructing an invocation request object for invoking the first function based upon the first and second sets of attribute-value pairs; and processing the result data returned by the first function based upon the second set of attribute-value pairs to generate a set of code executable to render a presentation of the result data in the user interface element. The second set of attribute-value pairs includes a first attribute-value pair specifying a data type for the result data and a second attribute-value pair specifying a first instruction for processing the result data.
