The Common Data Element Repository (CDER) Library is an online searchable repository of federal government program data elements/terms, definitions, and attributes. The 4 founding principles of the CDER Library are:

  1. Provide framework for, and access to, agreed-upon data standards
  2. Improve federal data transparency
  3. Promote consistency of federal business elements/terms, definitions, attributes
  4. Assist the Federal Government in Paperwork Reduction Act (PRA) processing
