DATA Act Information Model Schema (DAIMS)
For DAIMS users: This is the current version. Submission Calendars by Fiscal Year are available on the Resources Page.
Version 2.1 of the DAIMS released June 4, 2021. This release is necessary to support recent legislative and policy changes, such as agency tracking and reporting of COVID-19 supplemental spending as required by the CARES Act, ARP Act, and OMB implementation guidance M-20-21 and M-21-20. This release also supports Grant Reporting Efficiency and Agreement Transparency Act (GREAT Act) implementation, 2 CFR updates, an OMB Memorandum on Improvements in Federal Spending Transparency for Financial Assistance (M-21-03), and Grants Management (GRM FIBF) business standards updates. This release also includes reporting requirements for transitioning to the Unique Entity Identifier (UEI) from DUNS and initial steps to help integrate Budget Object Class (BOC) reporting in the Governmentwide Treasury Account Symbol Adjusted Trial Balance System (GTAS) to reduce agency burden and improve overall BOC data quality. Changes will be implemented in phases based on the timelines from the OMB memoranda, GSA SAM, and GTAS.
Related to the COVID-19 response, this release includes tying off the M-20-21 requirements that were outside of the DAIMS v2.0 timeline, updates to the Disaster and Emergency Fund Code (DEFC), and exceptions required for the ARP Act based on M-21-20:
- Beginning in FY 2022, all agencies, including those without COVID-19 spending, must begin reporting Files A, B, and C to USASpending.gov on a monthly basis, including award outlay data in File C, for all Treasury accounts reportable under the DATA Act.
- Allowing up to a 3-character DEFC to enable future disaster/emergency spending tracking and align with GTAS. This includes the elimination of a temporary non-standard code (DEFC ‘9’) and requiring all actual DEFC (including non-COVID codes).
- Modified validations to align with SAM registration/recertification flexibilities provided for in M-21-20. This enables financial assistance records to be submitted when federal awarding agencies relax the timing of the requirement for active SAM registration at time of application (or waive it entirely in certain ARP programs) to expeditiously issue funding.
Related to the GREAT Act, 2 CFR updates, M-21-03, and GRM FIBF update, financial assistance reporting changes are:
- Enable reporting of Indirect Cost Federal Share Amount to promote transparency. This aligns with GRM FIBF standards which requires this be reported in FY22.
- Enable optional reporting of the Funding Opportunity Number (FON) to provide transparency through linkage to pre-award information. This aligns with GRM FIBF standards which requires this be reported in FY23.
- Enable the optional reporting of Funding Opportunity Goals Text for program goals at the funding opportunity level. This provides the alignment with GRM FIBF standards which requires this be reported in FY23
- Updates the Award Description and Period of Performance dates data elements to improve data quality through clearer guidance.
- Transition to Assistance Listing from CFDA.
Related to the Unique Entity Identifier and Budget Object Class, changes are:
The release also includes other minor updates to clarify documentation, update validation rules to improve data quality, address agency feedback, add domain values, address changes in source system files, and provide additional metadata for data consumers.
