MarcEdit and MARCNext provide linked data tools for catalogers to experiment with BIBFRAME and linked data concepts. The MARCNext tools allow visualization of metadata in various BIBFRAME formats and embedding URIs. The Link Identifiers tool embeds URIs from sources like VIAF, ID.LOC.GOV, and FAST in authority fields. The SPARQL Browser allows querying SPARQL endpoints. The Zepheira training plugin transforms records for the LibHub initiative. However, many linking services are still evolving and local implementations vary, posing challenges for widespread adoption.
