The Contract Data Requirements List (CDRL) is usually contained in Part III, Section J of the government solicitation you are bidding and the executed contract upon award.
The CDRL is a register of the deliverable data items. Each data item has a discrete numeric identifier, a data item description (DID) number and a delivery schedule to the customer.
The CDRL is commonly conveyed on DD Form 1423 by the Department of Defense (DOD) specifying the delivery address, number of copies required and the reviewing and approving authority for the data item within the government agency. It also specifies electronic addresses if electronic data delivery is necessary. Forms other than a DD Form 1423 may be used to convey data item requirements by agencies outside DOD. That form may be as simple as a listing of requirements.
You should review the listing to insure adequate definition and understanding exist for you to commit to the data requirements when you sign your contract. Data Item Descriptions (DID's) are available at:

Although it is unusual to negotiate separate pricing for contract data, your negotiated contract and resulting budget baseline must contain the resources to prepare and submit contractually required data items.
On contracts for new products, data item submissions represent major benchmarks on the contract schedule. Results of study, research, engineering design and development are submitted in the form of data items to the government for approval.
Once approved, data items form the specifications for continuing effort on the contract. Key design reviews on development programs are focused on the contents of data item submissions.
Data item submissions contain reports of contract cost and schedule performance, results of status meetings and records of ongoing deliveries. Data item deliveries are key factors in demonstrating successful performance under the contract.
In some instances, the number of data items and the level of detail in each are negotiable with the government. Such negotiations have a direct impact on cost even though data items are not normally priced separately in the contract.
The cost for data item preparation and submission is usually included in the pricing in Section B of the contract within the prices for contract line item deliverable to which the data items apply.
SDRL or "Subcontract Data Requirements List" is a prime contractor flow-down of the CDRL requirements to a subcontractor.
Generally the prime will structure the SDRL to insure that subcontractor data submissions support the prime contract CDRL technical content, schedule and other parameters.
The prime may also take the liberty to incorporate additional requirement to support their own internal systems of quality,cost and schedule control.
As with CDRL requirements, SDRL's should be carefully priced within the end item CLIN's to which they apply to insure cost coverage.
