Bibliographic Framework Ontology (BIBFRAME)¶
The Bibliographic Framework Ontology (BIBFRAME) is an RDF-based vocabulary developed by the Library of Congress to modernize bibliographic description for libraries, museums, and archives [1] [2]. It provides a structured model for representing bibliographic resources, centered on core classes such as Work, Instance, and Item, together with properties for describing relationships, subjects, contributions, publication details, and other bibliographic characteristics [2] [1]. BIBFRAME is designed to support linked data publishing, semantic interoperability, and integration with other metadata standards, enabling richer discovery and reuse of bibliographic information [1] [2]. By providing an extensible semantic framework for bibliographic description, BIBFRAME supports the transition from legacy cataloging models to linked data environments in libraries and cultural heritage institutions [1] [2].
Example Usage: Describe a library book using BIBFRAME by linking the Work, such as Pride and Prejudice, to an Instance representing a specific edition and to an Item representing a particular copy held by a library, while also connecting the resource to authors, subjects, and related works for improved discovery and interoperability [2] [1].

Usage Example¶
Use the following code to import this ontology programmatically:
from ontolearner.ontology import BIBFRAME
ontology = BIBFRAME()
ontology.load("path/to/BIBFRAME-ontology.rdf")
# Extract datasets
data = ontology.extract()
# Access specific relations
term_types = data.term_typings
taxonomic_relations = data.type_taxonomies
non_taxonomic_relations = data.type_non_taxonomic_relations
