LRM/RDA/RDF at the University of Washington Libraries: A Timeline

Last updated 2022-04-05

LRM/RDA/RDF is our preferred ontology for representing RDA description sets as linked data. This post is meant to serve as a quick reference to the work we have done in this area, with links to accompanying documentation and presentations.

2016 Published Mapping of RDA Core to BIBFRAME 2.0 (mapping)

2019-2020 Received a subgrant and participated as a cohort institution in LD4P2 (project wiki). We began our work on LRM/RDA/RDF in Sinopia and expanded our earlier RDA to BIBFRAME mapping.

2020 Published expanded RDA/RDF to BIBFRAME Mapping and corresponding RML-based transformation tool. (mapping) (transform tool) 

2020 Began Sinopia MAPs project to produce updated LRM/RDA/RDF application profiles for use in Sinopia (project)

2021 Presented on LD4P2 work at ALA BCM-IG (recording)

2021 Presented on local LRM/RDA/RDF projects at SWIB21 (recording)

2021 Moderated panel at BIBFRAME Workshop in Europe, “What role can RDA/RDF play in the transition to linked library data?” (question slides) (recording) (Zapounidou slides) (Dunsire blog post) (Zapounidou blog post)

2021 Launched MARC21 Bibliographic to LRM/RDA/RDF Mapping Project (project)

RDA, BIBFRAME, and Modeling Bibliographic Relationships

This is the second of of two posts1 on the panel discussion “What role can RDA/RDF play in the transition to linked library data?” which took place during the fifth annual meeting of the BIBFRAME Workshop in Europe, and featured comments from five distinguished panelists. This post briefly summarizes and discusses comments provided by Dr. Sofia Zapounidou, a librarian at the Aristotle University of Thessaloniki and member of the Standing Committee of the IFLA Cataloguing Section.2 She was asked to respond to the following question during the event:

RDA has been painstakingly aligned with the LRM; BIBFRAME3 has not. One of the most talked-about areas of concern is the absence of an expression entity in BIBFRAME. Could this, or other incompatibilities between RDA and BIBFRAME, have significant impacts?

Gordon Dunsire on property chains and shortcuts in RDA/LRM

This is the first of two posts on the panel discussion “What role can RDA/RDF play in the transition to linked library data?” which took place during the 5th annual meeting of the BIBFRAME Workshop in Europe [1], and featured comments from five distinguished panelists [2]. This post is a transcription of the response from Gordon Dunsire (former chair of the RDA Steering Committee and current member of the RSC Technical Working Group [3]) to a question posed at the BIBFRAME Workshop, followed by an annotated version (annotated by Theo Gerontakos) engaging some of the areas discussed.

The question:

RDA/LRM/RDF contains elements that are essentially reified property chains in RDA, known as shortcuts, while BIBFRAME features many property chains that are not reified as specific elements – what many people call “nested” data. What are the pros and cons of property chains and reification, and do they cause interoperability problems?

Using RML to transform RDA to BIBFRAME

We have been developing a mapping document to convert RDA-in-RDF created during testing of the Sinopia Linked Data Editor at the University of Washington Libraries to BIBFRAME. In order to implement this mapping, we have been experimenting with the RDF Mapping Language (RML) produced by Ghent University’s IDLab. Using RML, we are able to transform RDA data as represented in RDF/XML into BIBFRAME data in either Turtle or N-quads.

Our progress so far is viewable in our GitHub repository, including sample data for transformation, working mapping documents, and examples of the output we have gotten using RMLMapper. Our most extensive mapping document (workMonographMap.xml.ttl) is designed to transform data created using our monograph application profile for entities classed as an RDA Work.

We hope that our RML mapping documents can serve as examples to others who are trying to utilize RML, as the current specifications for RML are an unofficial draft (last updated July 2020). The examples in the specifications represent relatively simple transformations, leaving RML users to craft their own solutions for any data or transformation slightly more complicated.

A Very Brief Overview of Past Semantic Web Research at the University of Washington Libraries

2012:

2012-2014:

2014-2016:

  • UW Libraries’ Cataloging and Metadata Services (CAMS) staff provide feedback on BIBFRAME 1 and 2 through Library of Congress (LOC) listservs and GitHub code repositories
  • CAMS staff prepare BIBFRAME training materials and offer sessions
  • 100+ MARC records are converted to BIBFRAME 1 and reviewed by cataloging staff
  • CAMS staff create an RDA Input Form as a proof-of-concept, demonstrating output of both RDA-in-RDF and BIBFRAME from input data

2016:

  • LoC releases BIBFRAME 2
  • Test conversion of MARC records to BIBFRAME 2
  • Comparative testing of searches on BIBFRAME data converted from MARC and digital-collections XML
  • CAMS publishes a mapping of BIBCO Standard Record RDA elements to BIBFRAME 2.0
  • First directed fieldwork in semantic web standards and data by a University of Washington iSchool student
  • CAMS publishes draft best practices for language tags in bibliographic linked data
