Abstract: A proactive repository stores authenticated information regarding Entities and their properties. A set of conditions and policies is associated with the information in the repository. These conditions govern the release of information to an authorized recipient. Release conditions include various forms of activation, such as activation of emergency services dispatch, a change in condition of a public utility, a change in geophysical or meteorological conditions, etc. At least one responsible third party can authenticate Entities, agents agencies and the like, validate associated credentials, and store received information in the repository. A first proactive repository can be stored within a second proactive repository. A proactive repository can provide the facilities of a multi-modal notification delivery system.
