Resources

The ADL Initiative produces research-based reports, technical specifications, how-to guides, software prototypes, and policy guidance. In most cases, these resources are provided to DoD and Federal government organizations under permissive government licenses. In many cases, these resources are also available to the general public under open-source licenses.
