This paper offers practical insights to enable governmental agencies and other parties to develop
the foundational legal documents for an IDS. The two primary foundational legal documents are
the memorandum of understanding (MOU) and data use license (DUL). The MOU is the agreement
among the parties that are contributing data to the IDS (“Data Contributors”) and the party that
is administering the IDS (“Lead IDS Agency”). The DUL is the agreement between the IDS and a
researcher, evaluator, or other outside party (“Data Licensee”) that sets forth the terms and conditions
under which it may gain access to data from the IDS for a specific purpose.
