Organization Information gone Wild: ROR, Entity IDs and The Organization Ontology

While building services for individuals from academia, uniquely identifying a person is a challenge that was widely addressed in several contexts like eduGAIN. Sometimes, alongside the “who?”, information systems also need reliable information about the “from where?”. During the past years several alternative standards came up to tackle that problem from different directions. In this paper we would like to introduce some of them: Research Organization Registry (ROR), eduGAIN Entities and The Organization Ontology and give an opinionated overview of how they can work together.
