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 annual release:
- Rebrands DAIMS as the Governmentwide Spending Data Model (GSDM). The rebranding is being done to include legislation and policies that go beyond the DATA Act.
- Adds new data element Program Activity Reporting Key (PARK), the outcome of the work of OMB and Treasury to streamline the process for agencies to submit Program Activities and improve data quality to align with the President’s Budget. This change will include new and edited validation rules and will impact agency submissions of Files B and C. This will also impact how agencies manage and submit program activity for OMB review and approval.
- Updates File B and C, as well as Validation Rules, to allow for Prior Year Adjustments (PYAs) for USSGL balance rows to close the PYA gap in presenting resources and obligations over time on USAspending’s COVID-19 pages.
- Adds support for Broker-Generated File A to be automatically added to agency submissions. The Broker-Generated file is based on agency submissions to GTAS and will increase data accuracy and reduce agency reporting burden. If an Agency prefers to use their own File A in lieu of the Broker-Generated version, they will have the opportunity to replace the Broker-Generated File A.
- Provides guidance to agencies on how to report Congressional Districts that changed in January 2023 due to 2020 census data.
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.
