module ActiveFedora::Rdf
##
# Module to include configurable class-wide properties common to
# Resource and RDFDatastream. It does its work at the class level,
# and is meant to be extended.
#
# Define properties at the class level with:
#
# configure base_uri: "http://oregondigital.org/resource/", repository: :parent
# Available properties are base_uri, rdf_label, type, and repository
