Linked Data for Production Linked Data for Performed Music A PERFORMED MUSIC ONTOLOGY EXTENSION TO BIBFRAME 2. 0 KEVIN KISHIMOTO NANCY LORIMER MLA ORLANDO 2017

Project description Develop a BIBFRAME-based ontology for performed music in all formats Domain-specific enhancements and/or extensions of BIBFRAME for use by the library community as a common standard Establish a model by which these standards can be created, endorsed, and maintained by the community Do this through partnering with domain communities and the PCC

Why ontologies? “An ontology is a formal naming and definition of the types, properties, and interrelationships of the entities that really or fundamentally exist for a particular domain of discourse. It is thus a practical application of philosophical ontology, with a taxonomy. ”* note this is an intellectual as well as a structural framework *Wikipedia, viewed January 2, 2017

Why BIBFRAME? Other ontologies: RDA registry (http: //www. rdaregistry. info) Music Ontology (http: //musicontology. com) DOREMUS (http: //www. doremus. org) BIBFRAME is: for all types of library materials, not just sound recordings compatible with a variety of cataloging content standards (or no standard) customizable, while still providing a common framework

BIBFRAME 2. 0 A very quick introduction…

New classes/subclasses/properties Subclass of bf: Title Subclass of bf: Identifier pmo: Announced. Title bf: Audio. Take pmo: Commonly. Known. Title bf: Gtin 14 Number pmo: Container. Spine.

Copyright. Date Working on classes & properties for: medium of performance events works

Thematic Catalog Numbers, Opus Numbers Current BIBFRAME properties bf: music. Thematic. Number literal bf: music. Opus. Number literal

Vocabularies why? to provide specific relationships not already in BIBFRAME to provide values for the objects of triples Example: bf: File. Type no subclasses/individuals in BIBFRAME want to add in:

Addition of vocabularies to: RDA vocabularies: bf: Applied. Material bf: Recording. Medium bf: Base. Material bf: Recording. Method bf: Carrier bf: Track. Config bf: Content bf: Tactile. Notation bf: Encoding. Format bf: Groove. Characteristics bf: File. Type bf: Playback. Channels bf: Music. Format bf: Playback. Characteristic bf: Music. Notation bf: Recording. Medium bf: Tactile. Notation bf: Recording. Method bf: Groove. Characteristics bf: Track. Config bf: Playback. Channels bf: Playback. Characteristic RDA unconstrained properties work relationship properties id. loc. gov vocabularies bf: Role

PMO Additions to bf: Carrier Additional vocabulary for bf: Carrier Labels: : Cd. Audio CD audio : DAT : Dvd. Audio DVD audio : Enhanced. CDAudio Enhanced CD audio : Ep. Record EP (Extended play) : Hybrid. SACD Hybrid SACD : Lp. Vinyl LP/Vinyl : SACD : Shellac 78 78/Shellac : Single 45 45/Single Note: In RDA, these would be used in addition to the RDA terms (Audio disc, Audiocassette)
