INFORMATION PROCESSING APPARATUS, METHOD OF CONTROLLING INFORMATION PROCESSING APPARATUS, AND PROGRAM

摘要

An information processing apparatus capable of adding a function by an extension program includes a registration unit, a setting unit, an execution unit, and a determination unit. The registration unit registers information on the extension program having an interface defined for each type of function. The setting unit sets a use condition of the extension program. The execution unit executes a process sequence by combining a plurality of extension programs according to a definition file defining the process sequence including a plurality of steps. The determination unit dynamically determines, when the process sequence is executed by the execution unit, extension programs that execute the respective steps of the process sequence according to information on the extension programs registered in the registration unit and the use conditions of the extension program set in the setting unit.
