DATA Act Information Model Schema (DAIMS) v1.2


Version 1.2 of the DAIMS architecture is the current release and includes the data standard conceptual model, specifications, and schema management. The DAIMS architecture is designed to meet the needs of the business users and technical systems.

It serves as the foundation for the DAIMS data standards. It is extensible through domain, component, element, and metadata. Additional descriptive content on the DAIMS architecture will be released as necessary.

DAIMS includes:

DAIMS Overview – provides an overview of the data standards and data architecture.

DAIMS Architecture – provides an overview of the data standards and data architecture.

Information Flow – provides an overview of the reporting timeframes and sources of the data included in the DAIMS across the federal enterprise.

DAIMS Reporting Guidance includes:

Reporting Submission Specification (RSS) – includes a listing of the data elements with specific instructions for federal agencies to submit content in the appropriate format.

The RSS is a human-readable version of the data standards. The previously separate Terse Labels (shortened versions of the data element names), Domain Values (permissible values for a sub-set of the DAIMS data elements), and DAIMS Diagrams (visual representations of how the data elements from the RSS fit together in context) have been incorporated to improve usability.

Interface Definition Document (IDD) – contains a listing of the elements, with supporting metadata, that explain what data will be pulled from government-wide systems for procurement and sub-awards and from the Broker itself (via FABS) for financial assistance.

The IDD is a human-readable version of the data standard for the award related content. The previously separate Terse Labels (shortened versions of the data element names) and DAIMS Diagrams (visual representations of how the data elements from the IDD fit together in context) have been incorporated to improve usability.

Validation Rules – documents the business rules employed by the DATA Act Broker for field and cross-file validations.
