The Entity Name System (ENS), applying the OKKAM razor principle, makes the systematic reuse of globally unique identifiers possible. The ENS stores the identifiers for entities and provides a collection of core services to support their creation, maintenance and pervasive reuse. The ENS is the result of a community effort, supported primarily by Okkam SRL and the University of Trento (Italy).
Each entity identifier in the ENS is persistently coupled with a set of attributes (i.e. a description) necessary to support matching, and therefore reuse. Among these, there are several geospatial features gathered from a set of sources including Geonames. These can be used to retrieve entities' identifiers based on their location.

A wide set of services are offered to support applications to retrieve entity identifiers. These are available to developers as SOAP Web Service or HTTP REST-like Web services, and to final users through web applications. You can try to query the ENS by the search-interface. If you want to edit description associated with identifiers, sign up to access our Entity Toolkit.
