This document discusses using functions as a framework for describing institutional records based on the International Standard for Describing Functions (ISDF). It presents definitions of key concepts like function, provenance, and fonds. It also outlines how functions can provide a model for classifying and relating records, agents, places, and time periods within an archival metadata schema. Specifically, it shows how the ICA metadata model incorporates entities for records, agents, functions and their interrelationships. Finally, it provides an example of using functions to document the activities of a university.
