Function-Based Dynamic Application Extension Framework

A method of developing a first application includes accessing a graphical user interface of a developer exchange system. The method includes, using the graphical user interface of the developer exchange system, selecting a first function from a plurality of functions in a function ontology. The method includes receiving, from the developer exchange system, processor-executable instructions for integration into the first application. The processor-executable instructions include (i) sending a function module request to the developer exchange system, (ii) receiving a function module provided by the developer exchange system, (iii) executing the provided function module, and (iv) presenting display data from the provided function module within the first application. The function module request identifies the first function. The method includes integrating the processor-executable instructions into the first application, including designating an area in which to display the display data to a user of the first application.
