Governmentwide Spending Data Model (GSDM)

Formerly known as the DATA Act Information Model Schema (DAIMS)

Please note that submission dates are published on the Resources Page

For GSDM users, this maintenance update:

1. Allows agencies the capability to submit older, backlogged awards by updating FABS validations rules to use the Federal Hierarchy’s Office Start and End Dates vs Expired Status to determine if the Office was active at the time the award was signed.
2. Updates Files B and C, as well as Validation Rules to align GSDM to OMB and GTAS requirements regarding two new USSGL accounts that were added to the SF-133 in FY23.
3. Updates validations A18, A19, and A35, to correctly check only the line with a PYA of X in File B.
4. Updates the RSS Required/Optional field for USSGL487200 and USSGL497200 to correctly reflect that it is "Optional (to be conditionally required for non-TOA (balance) rows for FY25).

This release also includes documentation fixes and enhancements. To understand all the changes and specific line-item details, agencies should review the GSDM Release Notes and the change logs of each document.

GSDM Technical Architecture

The Governmentwide Spending Data Model (GSDM) 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.

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

• GSDM Overview - What GSDM is, its scope, value, and approach
• GSDM Architecture - The GSDM conceptual model including a visual showing how domains, components, elements, and metadata go together in GSDM.
• GSDM 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.
