Following Cameron's invitation to suggest missing projects in the identifiers arena, I wanted to add to the list the OKKAM project, which is an EU project about assigning unique ids to entities (www.okkam.org). One of the goals is to provide an infrastructure (called Entity Name Server as an analogy to the DNS) that can be queried by describing an entity and that returns the entity's unique id. Such an infrastructure will be maintained beyond the duration of the project probably by an ad-hoc foundation. One of the entities we are focusing on are authors and we would like to provide the identification token described in this article OR collaborate with parties that are capable to provide it. Elsevier is one of the project partners and could contribute with Scopus data to the OKKAM repository.
