The Contract Data Requirements List (CDRL) is a list of authorized data requirements for a specific procurement that forms part of a contract. It is comprised of either a single DD Form 1423 or a series of DD Forms 1423 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. DFAR Subpart 215.470 requires the use of the CDRL in solicitations when the contract will require delivery of data.


Form:  DD Form 1423 – Contract Data Requirements List (CDRL)


CDRLs should be linked directly to Statement of Work (SOW) tasks and managed by the Program Management Office (PMO) data manager. Data requirements can also be identified in the contract via Special Contract Clauses (e.g., Defense Federal Acquisition Regulations Supplement (DFARS)), which define special data provisions (such as, Rights in Data, Warranty, etc.).


The purpose of the CDRL is to provide a standardized method of clearly and unambiguously delineating the Government’s minimum essential data needs. The CDRL groups all of the data requirements in a single place rather than have them scattered throughout the solicitation or contract.


Data Item Description (DID)
A DID is a completed document that defines the data required of a contractor and is included in a CDRL. The document specifically defines the data content, format, and intended use. There are standard DIDs for all topics that can be found in the ASSIST Database by entering their 5-digit DID number or searching for them by inputting “DI” into ASSIST – Quick Search.

Q. Is there a website that lists all data item descriptions?
A. All active and canceled DIDs are indexed in the ASSIST database. Once logged on, to print a preformatted listing of all DIDs in Adobe PDF format, click on the [DIDs] link on the left side of the page to get to the [DIDs Menu] and then click on the link for the [DIDs Browser]. The DIDs Browser allows you to generate a list of active DIDs, canceled DIDs, or all DIDs (both active and canceled). This same screen allows you to filter results by standardization area, preparing activity, or preparing service, or to search for DIDs by keywords. The resultant list will be generated in HTML but may be saved as a preformatted report in Adobe PDF format by clicking on the [Report] button at the bottom of the screen. The list may also be exported in Microsoft Excel format by clicking on the [Spreadsheet] button at the bottom of the screen. (Note: If you have never before used ASSIST, you’ll first need to register for a user account and password.)
Q. Where can I find an online copy of DoD 5010.12-L, “Acquisition Management Systems and Data Requirements Control List (AMSDL)”?
A. The AMSDL which formerly listed all DIDs, was canceled in 2007, as all DIDs have been incorporated into the ASSIST database.
