The C2 (Command and Control) Core was a DoD project sponsored by Joint Forces Command and the Office of the Assistant Secretary of Defense/Network and Information Integration (OASD/NII) to develop an open standard-supporting, extensible markup language (XML)-based command and control (C2) data exchange. It represents the first major implementation of the Universal Core v2.0, a federal information sharing initiative. It supports the DoD Net Centric Data Strategy by enabling data to be visible, accessible, understandable, trustworthy and interoperable. The overarching goal of this project is to support national and coalition warfighters by improving joint interoperability at the data and information layer.
