This section provides an overview of all the improvements, enhancements, fixes, and changes that appear in v2.1 of the Ed-Fi Data Standard.
Several changes to the data standard were made to improve and enhance capabilities for implementers. Significant changes include:
Additional detail and rationale for the changes discussed can be found in the following sections of this documentation.
The Common Education Data Standards (CEDS) initiative is a collaborative effort between the U.S. Department of Education and other federal agencies, state education agencies, local education agencies, private foundations, and vendors. CEDS produces a common vocabulary for education data, thereby streamlining data exchange and facilitating comparison across institutions and sectors. The Ed-Fi Alliance has participated in the CEDS initiative since the Alliance's inception, and the Ed-Fi Data Model has contained CEDS-aligned elements since v1.1.
In July 2016, CEDS v6.0 was released. Several elements and concepts were adopted, and Ed-Fi enumeration sets (types) were realigned.
Alignment of Data Standard v2.1 with CEDS v7.0 is underway. A mapping will be published in Q3 2017.
The Ed-Fi Extension Framework provides specific patterns implementers can use to customize the Ed-Fi Data Model while still retaining conformance to the Ed-Fi Data Standards. The Ed-Fi Data Standard v2.0 guidance allowed customizations in the field that proved problematic for implementers, particularly client systems. For example, v2.0 allowed required elements in the Ed-Fi Data Standard to be removed from an implementation. As another example, elements defined as optional could be changed to be required by an implementation.
The Ed-Fi Extension Framework guidance has been changed in v2.1 to remove a few problematic patterns such as the ones outlined above. Remaining patterns have not been changed. See the XML Schema - Extensions Framework Guide section of this documentation for the current patterns.
