Direct Known Subclasses:

DefaultIdentifierTranslator

public class PrefixingIdentifierTranslator
extends IdentifierConverter<org.apache.jena.rdf.model.Resource,FedoraResource>

A very simple IdentifierConverter which translates JCR paths into Fedora subjects with a configurable resource namespace (e.g., a baseURL). When a REST API context is available for constructing URIs, org.fcrepo.http.commons.api.rdf.HttpResourceConverter should be used instead.
