1. What is the CDER Library?

The Common Data Element Repository (CDER) Library was jointly authorized by the Council on Financial Assistance Reform (COFAR) and the Office of Management and Budget (OMB) in June 2014, to facilitate implementation of the DATA Act and encourage use of common data standards.  OMB assigned the Department of Health and Human Services (HHS) to provide tactical leadership for the DATA Act Section 5 Grants Pilot; CDER Library is part of the Pilot, and was designed to serve as an authorized source of data elements and data definitions used by the Federal government in agency interactions with the public. Initially populated with financial assistance information, the repository is designed to include data standards that have been approved through implementation of the DATA Act. CDER Library is managed by HHS in its role as executing agent for the OMB Section 5 Grants Pilot.

2. How does the CDER Library complement other sources of data standards; for example, Uniform Grants Guidance, OMB A-11?

The CDER Library is a repository of Federal government-wide, standardized data elements that consolidates information from authorized sources into a single library.

3. Where does CDER Library data come from?

Approved data elements in the public and Federal sections come from the Uniform Grants Guidance repository. Data elements available in the Federal section come from Federal agency forms or grant system documentation (e.g., online data collection systems). Currently, the Federal section includes data elements and forms from the following agencies/systems:

4. What is data harmonization?

Data harmonization is a standardized analysis process completed by the Department of Health and Human Services (HHS) to satisfy the requirements of the Digital Accountability and Transparency Act (DATA Act). The process identifies details about data elements reported to the Government and suggests ways to standardize, or harmonize, all data attributes across reporting mechanisms in the Federal grant life-cycle so information can be consistent across all forms and systems. The harmonized data elements proposed and hosted in the Common Data Elements Repository (CDER) Library move closer to Government-wide standardization.
