Government 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 version 1.1.1 focuses on the following improvements: 

  • Updating the Unique Award Key to use Agency Top-tier rather than Agency Sub-tier to reduce improperly linked awards on USAspending since Federal Award Identification Number (FAIN) is not unique government-wide. This addresses a GAO audit recommendation to improve data quality on USAspending. 
  • Governmentwide Treasury Account Symbol Adjusted Trial-Balance System (GTAS) requirements about SF-133 updates for two new United States Standard General Ledger (USSGL) accounts 480210 and 497210 that will be added to the SF-133 in FY26. 
  • Migration of subaward reporting from Federal Funding Accountability and Transparency Act (FFATA) Subaward Reporting System (FSRS) to SAM.gov. 

This update also includes small documentation edits and enhancements. To understand all the changes and specific line-item details, agencies should review the change logs of each document and the document linked below:
