The Ed-Fi Unifying Data Model is the widely adopted, CEDS-aligned, open-source data standard developed by the educational community for the betterment of the community. The Unifying Data Model captures the meaning and inherent structure of the most important information in the K–12 education enterprise.

The Ed-Fi Unifying Data Model, along with the normative and non-normative guidance in the Ed-Fi Standards, serve as the foundation for enabling interoperability among secure data systems.

Please note that the current version of Data Standard v3.3 is v.3.3.0-a, which contains early access content. Data Standard v3.3. is built on top on v3.2, so its elements are mostly consistent with v3.2. See the What's New page for information on the early access content.

Data Model Documentation

The data model is referred to as the Ed-Fi Unifying Data Model, or UDM. The UDM is documented via 2 primary artifacts: the Ed-Fi Data Handbook and a set of Unified Modeling Language (UML) diagrams.

Additional documentation is provided in the Ed-Fi Unifying Data Model section in this space. This additional documentation provides narrative overviews of domains and key entities, as well as normative best practice guidance.

Version

The most recent version and name for the Ed-Fi Data Standard is Ed-Fi Data Standard for Suite 3 v3.3.0-a. 

This is an "early access" release, meaning it contains newer data model changes that have yet to be proven in field work. Organizations wishing to avoid such early material – which is naturally subject to change – are advised to stick to elements defined in the current release – see Ed-Fi Data Standard v3.2 for information on those elements.

REST API Bindings

Current REST API bindings are based on previous Data Standard releases. However, since this release is non-breaking, the current 3.3.0-a release is backwards-compatible with those bindings. The relevant RFC bindings can be found here:

Bulk / XML Bindings

In addition, a set of Bulk / XML standards (core entity XML definitions and interchange specifications) based on this release are available on Github.
