Based on the Dublin Core metadata element set, the Publications Office of the EU has defined its own OP Core metadata element set. It consists of 16 elements that resources managed and published by the Publications Office through its OP Portal can and should contain. Extensions for specific domains, such as the legal or the general publications domains that go beyond the basic 16 OP Core metadata elements are being defined and will be published on the MDR website as soon as they are ready.
