Abstract

An apparatus, system, and method are disclosed for modular distribution and maintenance of non-“object code only” (OCO) dynamic components. OCO components comprise compiled executable modules. Non-OCO components comprise user readable and/or editable components. The modular distribution of non-OCO components comprises updating a skeleton data set comprising text and component fields such that user customizations and developer customizations are preserved. The modular distribution further allows for the generation of an output data in response to a reportable operational event, wherein the output data set is based on the skeleton data set and user customizations and developer customizations stored in customization data sets.
