DAIMS Technical Architecture

The DATA Act Information Model Schema (DAIMS) is the authoritative source for the terms, definitions, formats, and structures for hundreds of distinct data elements that tell the story of how federal dollars are spent.

DAIMS gives federal agencies guidance about what data to report to Treasury, where to get that data, and how to submit it.

To learn more:

• DAIMS Overview  – What DAIMS is, its scope, value, and approach
• DAIMS Architecture  – The DAIMS conceptual model including a visual showing how domains, components, elements, and metadata go together in DAIMS
• DAIMS Information Flow  – A technical flowchart showing how data comes into, flows through, and is reported out, including how often that happens and where the data come from.
