Founded in 1997, the DOI Foundation is a not-for-profit organization. We govern the Digital Object Identifier (DOI) system on behalf of the agencies who manage DOI registries and provide services to their respective communities. We are the registration authority for the ISO standard (ISO 26324) for the DOI system and we are governed by our Registration Agencies. The DOI Foundation is an international community of communities bound by a common interest in persistent infrastructure. So far, we have welcomed agencies that manage communities spanning entertainment, standards, the built environment, natural history collections, scholarly communications, and research data.
