In 2019, the PCC launched a URIs in MARC Pilot to engage metadata practitioners in formally applying techniques to further the PCC’s linked data transition.  In the years prior to 2019, several PCC task groups and committees had been laying the groundwork for practical implementation of linked data:
PCC Linked Data Advisory Committee
PCC Task Group on Identity Management in NACO
PCC Task Group on URIs in MARC
PCC Task Group on Linked Data Best Practices
Other PCC groups, including the Standing Committees, were also looking at linked data topics.

The URIs in MARC Pilot was a logical outgrowth of this groundwork.

Much of the work on linked data is in response to the PCC Strategic Directions 2018-2021, specifically Strategic Direction 3, Apply understanding of linked data, and Strategic Direction 4, Accelerate the movement toward ubiquitous identifier creation and identity management and the network level. As a result of the efforts of various PCC groups, resources available to catalogers now include a set of recommendations outlined in the Final Report of the PCC Task Group on Linked Data Best Practices, and in the FAQ and Formulating URIs documents developed by the PCC URI Task Group on URIs in MARC. In addition, in 2020, the authorities subgroup of the URIs in MARC Pilot created a document with best practices on recording URIs in the 024 field of NACO Authority Records.

The PCC URIs in MARC Pilot tested and developed PCC best practices for some of the areas the Linked Data Best Practices Group had identified, and some of the topics addressed in the FAQ developed by the PCC URI Task Group on URIs in MARC:

  1. Use of RWO URIs vs traditional library identifiers
  2. Use of identifiers from traditional as well as nontraditional sources
  3. How to record alternative identifiers from multiple sources
  4. Preference among vocabulary sources
  5. Use of the 024 field in NACO authority records to end the temporary moratorium on adding 024 fields 
  6. Implications for local and shared practice
  7. Other use cases

Pilot members worked with bibliographic records and/or authority records. The bibliographic work was done in participants’ local systems, or WorldCat, or both. Pilot participants were drawn mostly from PCC institutions or partner communities. 

Reports of subfield $0 and $1 editing activity in non-local environments (shared files) was obtained during the initial months of the pilot and was used to identify any policy issues that need discussion in the PCC Task Group on Identity Management in NACO. 

The PCC URIs in MARC Pilot had immediate oversight and guidance from the PCC Task Group on Identity Management in NACO, with consultative roles by the Linked Data Advisory Committee, the Standing Committee on Standards, and OCLC.

Much of the exploration the PCC has done on linked data is now open to PCC members at the practitioner level, to continue to chart a PCC path forward into a linked data future. We have seen growing interest in this type of work in recent times. For example, members from the former PCC ISNI Pilot are already applying linked data concepts in their work.
