The namespace info:eu-repo is registered at http://info-uri.info
This name space is an authoritive placeholder for semantic terms, controlled vocabularies and identifiers.
By using this namespace all the terms used have a "web presence". Therefore it is no longer an arbitrary string, but contains meaning. This utilisation makes it future-proof.
The INFO URI namespace has been DISCONTINUED since 22 May 2010!! The website info-uri.info writes: "it has been deemed appropriate to close the registry to further "info" namespace registrations. The "info" registry will continue to be supported for the foreseeable future, although prudent adopters should consider migrating their resource identity requirements towards mainstream Web practices over the long term."
The already existing info:eu-repo namespace will NOT be DISCONTINUED. But will migrate toward mainstream Web practices applicable for Linked Data. Steps involve in prefixing the name space by the purl.org URL. Second to create OWL descriptions for each element in the namespace, making it possible for machines to understand the identified content.
The info:eu-repo URIs are persistent identifiers for non-informational resources. Such non-informational resources include classifications and "real world objects". One important category is concepts; concepts are classes or properties. For these a subclass of the info:eu-repo URIs is introduced: the info:eu-repo/semantics URIs. The info URIs are not resolvable which makes them ideal as persistent identifiers of abstract things like concepts. On the other hand there is a need to link the URIs to their semantics. In the Semantic Web this is done by a redirection to a RDF document in which the semantic relations of the object for which the URI stands are described. We propose a service that supports URIs of the following form: http://purl.org/info:eu-repo/... (which is the same as http://www.purl.org/info:eu-repo/... - default hostname is "www"). The URI http://purl.org/info:eu-repo/semantics URIs results in a 302 redirection to a RDF document in which the concepts for which the URIs stand are described.The namespace is an authoritive placeholder for semantic terms, controlled vocabularies and identifiers. By using this namespace all the terms used have a "web presence". Therefore it is no longer an arbitrary string, but contains meaning. This utilisation makes it future-proof.The purpose of the info:eu-repo registry is not to create a comprehensive, complete ontology. Instead its purpose is to fill holes. The registry introduces terms with which existing ontologies can be complemented and connected with each other.
