The Schools Interoperability Framework, or SIF, is an open specification that enables disparate K-12 applications to interact and share data. Applications communicate on a SIF Zone through an intermediary known as an agent.

Uva Core is an open solution that simplifies writing SIF agents by abstracting the nuts and bolts of the SIF specification to high-level classes, allowing schools, vendors, and integrators to write powerful agents with nothing more than a basic understanding of SIF and a little Java.
