In United States Government contracts, the Contract Data Requirements List (CDRL) is a list of authorized data requirements for a specific procurement that forms a part of the contract. It consists of either a single DD Form 1423-1 or a series of individual CDRL forms containing data requirements and delivery information. The CDRL is the standard format for identifying potential data requirements in a solicitation, and deliverable data requirements in a contract. Subpart 215.470 of the Defense Acquisition Regulations System (DFARS) document requires the use of the CDRL in solicitations when the contract will require delivery of data. Guidance on how to fill in and handle the DD Form 1423-1 is provided in publication 5010.12-M.
