Reasonable Graph

ReasonableGraph is an open-source generic web-based platform for the management of digital and physical collections organized in ontology models, hopefully suitable for libraries, archives or museums. You may preview additional information on the platform on the project’s website:


The platform provides a generic editing environment on which we have implemented the BIBFRAME data model thus enabling native BIBFRAME based cataloging workflows and organizing records in the BIBFRAME standard.


There is an online demo available at:

We provide access to the demo upon request


The demo aims to provide an enterprise level experience of handling, searching and retrieving data that adheres to the BIBFRAME standard, while also depicting the ability to extend and customize pre-existing standards, which is most relevant for users and cataloguers from the library, archive and museum domains. The demo provides an indicative installation of the BIBFRAME standard; its main goal is to display the feasibility of the current approach.


As a new open-source project, ReasonableGraph aims for the maximum reception and adaptation in order to meet the domain experts’ needs.


Additional Highlights

  • Supports a wide range of ontology models
  • Utilizes property graphs for the storage layer
  • Includes a rule engine with inference support UI
  • Views and forms are customizable in a declarative configuration form

Status: Available for use.

Library of the Hungarian National Museum

The Library of the Hungarian National Museum has published the entire online catalog into the LOD cloud in BIBFRAME format. We also provide links to external sources like: BNF, ISNI, LC NAF, VIAF and Wikidata. We provide a SPARQL endpoint as well:

One of the aims of this publication is to make Hungarian librarians more familiar with BIBFRAME. In order to achieve this the BIBFRAME and the MARC descriptions are cross linked. Knowing the BIBFRAME URI of an instance, for example:

one can get the MARC description by appending ".opac":

Knowing the permalink of an OPAC record:

one can get the BIBRAME description in HTML format by appending "rdf”:

Other formats can also be invoked by appending the following extensions: ".rdf-ttl", ".rdf-nt", ".rdf-json", ".rdf-jsonld", and ".rdf-rdf" (for rdf/xml).

Clicking the BIBFRAME icon in the OPAC also leads to the BIBFRAME description.

Full documentation can be found here:
and here:

The project was carried out in partnership with @Cult srl., Italy (MARC BIBFRAME conversion) and Monguz Ltd., Hungary (OPAC modification). We also used some parts of the ALIADA open source tool.

One of the main characteristics of the MARC BIBFRAME conversion is the reconciliation of works. The example URI above is a good example of that.

The BIBFRAME dataset will be updated periodically as BIBFRAME and the conversion evolves.

Colorado College

Colorado Alliance of Research Libraries BIBCAT Pilot

A joint project with the Colorado Alliance of Research Libraries ( and, we are publishing BIBFRAME 2.0 RDF as validated JSON-LD for indexing by Google and other search engines through an XML sitemap. Over 160,000 source MARC21 records from the Alliance’s Gold Rush Comparison service, representing random samples from the ILS catalogs of Colorado College and University of Colorado Boulder, were used in the first release. These MARC records were initially transformed into BIBFRAME 2.0 RDF using custom mapping RDF rules. Currently in its second development sprint, this project now uses the recently released LOC’s marc2bibframe2 project as a starting point for enhancing BIBFRAME graphs for improved search ranking of academic libraries collections with geolocation support. Source code repository is available on Github at

Plains2Peaks Collective

This project is a new BIBCAT-based DPLA Service Hub for Colorado and Wyoming that uses RDF Mapping Language ( rules to map different metadata vocabularies and formats (MODS, Dublin Core, CSV, custom XML) into BIBFRAME 2.0 RDF triples. These BIBFRAME RDF triples are loaded into a triplestore and will be published as DP.LA MAPv4 JSON-LD accessible through a ResourceSync feed. Partners in the initial pilot include the Colorado State Library, University of Wyoming, MARMOT Library Consortium, Denver Public Library, Wyoming State Library, Colorado College, and History Colorado Museum.

Stanford University

Application: Linked Data for Production (LD4P)

Description: Linked Data for Production (LD4P) is a collaboration between six institutions (Columbia, Cornell, Harvard, Library of Congress, Princeton, and Stanford) to begin the transition of technical services production workflows to ones based in Linked Open Data (LOD). This first phase of the transition focuses on the development of the ability to produce metadata as LOD communally, the enhancement of the BIBFRAME ontology to encompass the multiple resource formats that academic libraries must process, and the engagement of the broader academic library community to ensure a sustainable and extensible environment. As its name implies, LD4P is focused on the immediate needs of metadata production such as ontology coverage and workflow transition. The LD4P partners’ work will be based, in part, on a collection of tools that currently exist, such as those developed by the Library of Congress (used by LC and Stanford) andVitro (developed by Cornell and used by Cornell and Columbia). The cyclical feedback of use and enhancement request to the developers of these tools will allow for their enhancement based on use in an actual production environment. The focus of LD4P is on the adaption of this current tool suite to immediate production needs. LD4L-Labs, in turn, will focus on solutions that can be implemented in production at research libraries within the next three to five years. Their efforts will focus on the enhancement of linked data creation and editing tools, exploration of linked data relationships and analysis of the graph to directly improve discovery, BIBFRAME ontology development and piloting efforts in URI persistence, and metadata conversion tool development needed by LD4P and the broader library community. The project as a whole will be supported by the LD4P Program hosted at Stanford University.

German National Library

Application: BIBFRAME prototype in DNB OPAC

Description: From the full presentation of a record there is an action option called "BIBFRAME-Repräsentation dieses Datensatzes" (i.e. BIBFRAME representation of this record) which triggers a conversion process based on BIBFRAME version 1.0.

An update is planned and prepared to be implemented in 2018, using BIBFRAME 2.0. Further steps will develop the prototype into a productive service, along the international developments of BIBFRAME.

BIBFRAME 1.0 Implementations

The following BIBFRAME 1.0 Implementations were previously listed and will be deleted in the near future.

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.

Library of Alexandria

  • Description: The Library of Alexandria aims to be a center of excellence for the production and dissemination of knowledge, and to be a place of dialogue and understanding between cultures and peoples. And as one of the biggest Arabic Libraries in the middle east, we would like to contribute in the conversion process, testing and tools development of the Bibframe initiative, where the BA would play a major role in the Arabic component, as its Library collection contains a variety of MARC records for books, rare books, manuscripts, serials and maps, especially in the Arabic Language.

  • Implementation Status/Plans.
    1. Our ICT LIS admin team with expertise in software development related to Library Information Systems is dedicated to work on and increase its manpower for this initiative.
    2. We will be testing the BIBframe vocabulary, data model, editor and tools by converting MARC records of the BA collection to Bibframe.
    3. We will contribute to the creation of new Arabic BIBFRAME records, as well as the conversion tool development for the Arabic Language.
    4. We will provide feedback on conversion issues we encounter using the tools, the BIBframe vocabulary, and the data model.
    5. A progress report can be expected by mid 2015.

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.

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.
