The Library of Congress > BIBFRAME > Implementation, Tools, and Downloads > Implementation Register

The BIBFRAME implementation register is established to list BIBFRAME implementations - existing, developing, and planned. It will be maintained here. Any organization implementing a BIBFRAME project or application can be listed. If an organization has multiple BIBFRAME projects it may have each listed in a separate entry. See Implementation Register Guidelines

University College London Department of Information Studies

  • Application: Linked Open Bibliographic Data Project

  • Implementation details: A team from UCL Department of Information Studies has been awarded an Elearning Development Grant (ELDG) from UCL ELE (E-Learning Environments) to develop a Linked Open Data bibliographic dataset based on BIBFRAME. BIBFRAME enables semantic-interlinking of bibliographic datasets on the Web, and improves the interaction with web users by enabling them to access, retrieve and update bibliographic records online. The aim of this project is to develop a BIBFRAME dataset as an Open Educational Resource, which will help students learn the new standard in an interactive way, and at the same time become familiar with state-of-the art web technologies. An important aspect of the project is working with students from the MA LIS programme to develop and evaluate the resource. Full details:

  • Implementation status: Currently in Phase 1 Pilot,: creating a subset of data that will be published on the web.

University of Illinois at Urbana-Champaign Library

  • Description: The University of Illinois at Urbana-Champaign Library has been working to examine aspects of the BIBFRAME model related to ebooks. The intent is to test if ebooks works well with the BIBFRAME vocabulary, and the BIBFRAME model. We will convert our 300,000 ebooks from MARC to BIBFRAME. We will develop an interface for users to search for those 300,000 ebooks via the BIBFRAME model. We plan to provide the community with issues during conversion, as well as issues with work, instance, annotation, and authority for ebooks.

Music Library Association (MLA)

Description: The Music Library Association is working to examine aspects related to music in the Library of Congress’s MARC to BIBFRAME Transformation Service as part of a broader effort to develop BIBFRAME profiles for music. We plan to provide feedback on conversion issues, use cases, and functional requirements, as well as to contribute to the BIBFRAME vocabulary and data model.
Our pilot project begins with an in-depth look at how medium of performance is handled in the MARC-to-BIBFRAME conversion process. We will examine technical issues such as grouping, ordinality and cardinality, and how these aspects translate to musical designations such as soloists, accompaniment, number of players to a part, instrumental and voice doubling, and instruments sharing.

The National Library of Medicine

  • Description:  Short Term (4-6 month) BIBRAME Experimentation Plans:
    1. Develop a more modular approach to the BIBFRAME vocabulary, by paring down the existing vocabulary to core concepts in wide use among different communities. Rather than trying to make BIBFRAME encompass all vocabulary needs of every community, we think it would be beneficial to investigate the viability of a modular approach in which a core BIBFRAME vocabulary is extended by other rdf vocabularies (e.g. MODS.rdf, RDA.rdf, PRESOO.rdf, etc.) for concepts specific to a community or resource.  We believe this approach will encourage the adoption of BIBFRAME outside the library community.
    2. Modify the Zepheira marc2bibframe conversion code to reflect a core BIBFRAME vocab and run a sample set of existing MARC records.
    3. Modify the LC BIBFRAME Editor or create an NLM profile on the Zepheira Scribe tool to represent core  BIBFRAME vocabulary terms and NLM-specific needs, and then create new bibliographic data. 
    4. Develop a transformation to convert MARC authority records into BIBFRAME supplemented by other vocabularies as needed.
    5. Set up a triple store on a server in order to save, query, and relate NLM’s BIBFRAME test data and authority files.

Columbia University Libraries

  • Description: As part of the 2CUL Technical Services Initiative, a collaboration between Cornell and Columbia University Libraries, we are testing the BF vocabulary and data model by converting MARC and MODS records for all formats from Columbia’s broad collections. We will also assess available BIBFRAME tools and test the BIBFRAME Editor for the creation of new BIBFRAME descriptions. We will provide feedback on conversion issues encountered using the tools, the BF vocabulary, and the data model. The intent of Columbia’s participation is to contribute to vocabulary & tool development.
  • Implementation status: Formation of a team consisting of staff members with rare book, serial, law and non-MARC expertise. Training in progress. Record conversion in progress. (A progress report can be expected in early  2015.)

Princeton University Library

  • Application: NjP BIBFRAME Analysis, second phase

  • Description: Princeton is converting and reviewing existing MARC records with a focus on music material, rare books, and non-roman script records.  Princeton will also test the BIBFRAME Editor for creation of new bibliographic data.  The intent of Princeton’s experimentation will be to analyze the BIBFRAME vocabulary and model with regard to cataloging standards.
  • Implementation status: We tested individual and bulk record conversion and reported conversion issues to LC.  We are working to establish a connection between the BF editor and a data store and will provide feedback.  We are evaluating the possibility of using the editor for production work rather than just testing by creating original descriptive data for small projects. We have begun discussing use cases which could demonstrate the benefits of linked data for our users, and we are experimenting with enriching our bibliographic data with URIs in preparation for large-scale conversion.

German National Library

  • Application: BIBFRAME prototype in DNB OPAC

  • Description:  From the full presentation of a record in the OPAC of the German National Library, there is now an action option called "BIBFRAME-Repräsentation dieses Datensatzes" ("BIBFRAME Representation of this Record").  By clicking a link the record is converted from Pica+ into BIBFRAME (in RDF/XML) and offered for download. 
    Behind the link is a conversion process triggered "on the fly", itself based on a mapping from PICA+ to BIBFRAME.

  • Link:

  • Status: This is a starting point for further developments, notably, to synchronize with the "Vocabulary 1.0" published by the Library of Congress in January 2014.

Biblioteca Nacional de Cuba “José Martí” (BNJM)

  • Application. Retrospective conversion using BIBFRAME

  • Description: BNJM is working to implement BIBFRAME as part of a strategy to finish the retrospective conversion of its printed catalogs. The current online catalogs include bibliographic references since 1998 and the previous bibliographic references remain in printed cards catalogs. The library will also test the conversion of existing MARC records (from 1998) to the Linked Data Model of BIBFRAME using the conversion made available by the Library of Congress (LC) .
    We are digitizing the printed card catalogs and creating a virtual catalog of card images or CIPAC (Card Images Public Access Catalog). In order to link the cards with the Web of Data, we are using a hybrid approach to annotate its data. The annotation combines OCR techniques, crowd and specialists annotation, use of VIAF, ISNI and other LOD sources and quality reviews translating the annotations to RDF. The creation of linked data is consistent with the BIBFRAME model.  

    We encourage the idea to include Catalog Cards as a class of annotations of work instances, similar to the Cover Art Annotation  Class in the BIBFRAME model.  In fact we have been modeling the Catalog Card Class in a way similar to that of the Covert Art Annotation Class and that could be a solution for this USE CASE respecting the standardized efforts of BIBFRAME.  

    We plan to publish a first set of the BIBFRAME data of our holdings as part of the Linked Open Data space at the first trimester of 2015.  We are very interested to test interoperability issues with other libraries and agencies.

  • Implementation status: We already have created the CIPAC of the Printed Cards Catalog of books of the Cuban Collection of XIX century and we began the annotation process using the mentioned tool. We would welcome the definition of the above mentioned annotation class in order to advance the creation of linked data using BIBFRAME model.

Stanford University

  • Application: Linked Data for Libraries (LD4L)

  • Description: The goal of Linked Data for Libraries (LD4L) is to create a Scholarly Resource Semantic Information Store (SRSIS) model that works both within individual institutions and through a coordinated, extensible network of Linked Open Data to capture the intellectual value that librarians and other domain experts and scholars add to information resources when they describe, annotate, organize, select, and use those resources, together with the social value evident from patterns of usage.  LD4L plans to use BIBFRAME as the common model for all bibliographic data.  The initial focus will be on MARC data conversion but the conversion of other standards (e.g. MODS) will be a focus as well.  The three universities involved (Cornell, Harvard, Stanford) plan to develop a common data store and shared light abstraction layer.  The anticipated discovery layer will be Blacklight.

  • Link:

  • Implementation status: Initial focus is on MARC record conversion and the development of an ontology for usage data.  The group is making a large scale test of the BIBFRAME converter, examining all MARC fields and formats, and reporting technical issues to Github and conceptual issues to the BIBFRAME testbed.

Colorado College

  • Application: TIGER Web Catalog & Flask-BIBFRAME Extension

  • Description: BIBFRAME is a critical Linked Data vocabulary being developed in the open-source project, Flask-BIBFRAME (, a component of the Cataloging Pull Platform. On February 27th, Colorado College is releasing a Minimum Viable Product (MVP) web catalog, called TIGER (source code available at, that uses the Flask-BIBFRAME extension. TIGER uses Linked Data entities using source records from their MARC-based legacy ILS  and Fedora Commons digital repository.  The TIGER web catalog’s user interface is based on Aaron Schmidt’s design at and uses the following technologies: Flask micro web framework for the web server and middleware. Solr Index for searching.  Redis for analytics, result caching, and messaging. MongoDB document store for JSON-LD representations of BIBFRAME entities using RDA,, MARC, and other vocabularies.
           Other BIBFRAME experiments that preceded to the development  of the TIGER web catalog include the Summer 2013 Union Library discovery app that uses an earlier version of the BIBFRAME vocabulary and is available at A later BIBFRAME prototype was developed that directly used Schmidt’s UI design from his blog with the 40,000+ RDF records from Project Gutenberg and can be viewed at The source code for both BIBFRAME prototypes is available at

Library of Congress

  • Description:
    • MARC to BIBFRAME Transformation Service
      The transformation tool uses LC's MARC2BIBFRAME transformation to convert an existing marcxml record or collection to bibframe. Records can be pasted in or addressed by url.
      The transformed records will be shown in Exhibit, with the ability to see the original marcxml , bibframe rdf, and json. Records can be re-transformed if the MARC2BIBFRAME code has been updated. Link:      Status: Available for use.

    • MARC to BIBFRAME Comparison Service
      The comparison tool takes a record number (marc 001) and transforms that LC record, showing either marcxml or bibframe results. Possible new development: lccn as the input.
