Audio Visual and Sound Recordings Collections: This project will explore best practices for creating Linked Data descriptions for Library of Congress resources for audio visual and sound recording resources (AV). A major study was commissioned by the Library in 2014 regarding data models for AV data, and another study is being prepared that analyzes the need for technical and preservation metadata in bibliographic descriptions. The recommendations from these studies need to be integrated into the BIBFRAME model and the BIBFRAME vocabulary adjusted. LC will be a part of Stanford’s Music Ontology Project and together with that group will formalize the extensions to the BIBFRAME ontology. That activity will be part of this project and also the Library of Congress Vocabulary 2.0 project. In addition, this project will evaluate the thesauri and controlled vocabularies best suited to describe audio visual and sound recording resources in a linked data environment. Deliverables will include: 1) BIBFRAME Editor profiles for audio visual and sound recording resources; 2) a searchable BIBFRAME database of descriptions that consists of converted MARC authority and bibliographic records from the LC/ NACO Authority File and the Library of Congress bibliographic database; 3) a set of BIBFRAME descriptions for audio visual and sound recording resources; 4) a written evaluation of the project and recommendations for future research and development; and, 5) a presentation of project findings to appropriate library organizations and linked data communities.
Prints and Photographs: This project will explore best practices for creating Linked Data descriptions for Library of Congress print and photograph resources. This material has special characteristics such as uniqueness of items and derivative material for items. As a result the Resource Description and Access (RDA) provisions are not closely followed in cataloging this material and the community has indicated that other data models may apply to the material. The project will evaluate BIBFRAME’s effectiveness as a data model for describing print and photograph resources, taking into account the differences in cataloging rules and the Visual Resources Association standards.27 In addition, the project will evaluate the thesauri and controlled vocabularies best suited to describe print and photograph resources in a linked data environment. Deliverables will include: 1) BIBFRAME Editor profiles for print and photograph resources; 2) a searchable BIBFRAME database of entries that consists of converted MARC authority and bibliographic records from the LC/ NACO Authority File, the Library of Congress bibliographic database, and the Thesaurus for Graphic Materials ; 3) a set of published BIBFRAME descriptions for print and photograph resources; 4) a written evaluation of the project and set of recommendations for future research and development; and, 5) a presentation of project findings to appropriate library organizations and linked data communities.
BIBFRAME 2.0: This project will continue the development of an RDF vocabulary that can be used broadly in the library and cultural heritage environment. At this point BIBFRAME is built on a vocabulary that was stabilized for a year by the Library of Congress to enable experimentation with the BIBFRAME Model. In early 2015, The Library began to analyze the comments that had come from the community over the past year, engaged a consultant to review and provide advice on the vocabulary, and began to make proposals for change to the vocabulary, dividing it into functional parts. There is much to be done to publish the revised specification (2.0) which is based on these reviews. The techniques for extending the vocabulary to accommodate the different resource models and requirements of unique material like that for still image material, audiovisual data, and archival collections need to be developed, and the relationship of bibliographic metadata to technical metadata needed for resource preservation activities studied. The LD4P projects will also investigate descriptions of specialized resources and collaboration with and among those projects will help lead to a viable end result. Early in the project year, LC will make available to the BIBFRAME community drafts of the BIBFRAME 2.0 vocabulary proposal, revised BIBFRAME model, namespace documentation, and recommended extension framework via the Web and RDF, for use by the community and for others in LD4P. The development will be tested through pilot activity.
BIBFRAME and RDA: This project will explore the BIBFRAME and RDA28 data models and best practices for creating linked data descriptions for Library of Congress resources in monograph, serial, notated music, and cartographic formats. These are data types at the Library that are most actively using the Resource Description and Access (RDA) cataloging provisions and this project will investigate the compatibility of the RDA and BIBFRAME models. BIBFRAME’s effectiveness for describing those resources for user needs will also be evaluated. In addition, the project will evaluate the thesauri and controlled vocabularies best suited to describe monographic, serial, notated music, and cartographic resources in a linked data environment. By the end of 2016, LC will make available to the library community: 1) BIBFRAME Editor Resource Description & Access (RDA) profiles for monographic, serial, notated music, and cartographic resources; 2) a searchable BIBFRAME database of entries that consists of converted MARC authority and bibliographic records from the LC/ NACO Authority File and the Library of Congress bibliographic database; 3) a set of BIBFRAME descriptions for monographic, serial, notated music, and cartographic resources; 4) a written evaluation of the project and recommendations for future research and development; and, 5) a presentation of project findings to appropriate library organizations such as the American Library Association (ALA) and linked data communities.
