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 release focuses on implementing regulatory mandates and OMB policy updates, which will allow agencies to ensure full compliance with these changes.

The key drivers for this 2024 release are to reflect:

1. updates to the Financial Assistance Broker Submissions (FABS) to ensure compliance with recent OMB policy and/or 2 CFR,
2. updates to the Interface Definition Document (IDD) to ensure continued alignment with FPDS v1.5 in terms of metadata such as FPDS definitions, XML Tags, domain values, etc.
3. guidance on a new Data Broker report for comparing File B and GTAS data elements, such as Budget Object Class,
4. continued rebranding of the GSDM and Data Broker.

This release also includes minor documentation edits 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.

To learn more:

• 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.
