Aligning BIBFRAME with The Schema/Bib Extend model Carol Jean Godby, Senior Research Scientist, OCLC BIBFRAME Update session, ALA 2013 Chicago, Illinois, USA Aligning BIBFRAME with The Schema/Bib Extend model

Bibliographic Descriptions in Schema.org: Rationale Increase the visibility of library resources in the major search engines. Engage at the W3C level for representation of library data. Address defects in the Schema model for representing bibliographic data. Discovery vs. curation

The context OCLC’s alpha release of linked data for WorldCat.org. The BIBFRAME Early Experimenters group. The Schema Bib Extend W3C Community group. OCLC’s experiments with SchemaBibEx and BIBFRAME. #1 Available on WorldCat.org. Schema.org + vocabulary extensions for describing library resources. Focuses on physical formats. #2 Covers some of the same ground. Has some of the same goals: A collection point for descriptions about library resources Vocabulary development with OCLC’s draft. #3 Open community group hosted at w3c.org Goals: experiment with describing library resources using schema.org and allied standards – in just enough detail to support discovery. Assume that standards developed in the library community (such as BF) will fill in the rest. make recommendations to Schema.org managers for vocabulary that makes life easier. disband. #OCLC’s experiments Use SBX philosophy (see how far schema.org can go) Identify places to plug in library community standards. develop and experiment with models #4 OLC’s comparisons tasked with this job as a member of BFEE. generated BF markup on all of WC.org – with the same process as Schema.org markup. used to identify broad similarities – synonymous vocabulary, etc. manually created exemplars illustrating experimental models and compared those with BF.

Schema.org and BibFrame: big alignments Data coverage Modeling detail Schema.org BibFrame

SchemaBibEx and BIBFRAME: Similarities Schema.org and BIBFRAME can be used to describe the same resource. Many concepts have the same meaning. For example: Person, Organization, Place, Author, Director, ISBN, Hardcover, Audiobook, ‘label and ‘name,’subject’ and ‘about.’ The overlapping descriptions are similar to a Dublin Core Terms record.

Issues Representation of FRBR Works and Expressions in Schema.org Alignment of BIBFRAME Authorities and Annotations Moving beyond the Dublin Core-like description

A recommended division of labor SchemaBibEx advocates lead BIBFRAME leads Evaluate Schema.org for library descriptions. Negotiate with Schema.org to adopt changes. Map BIBFRAME concepts to Schema.org. Develop BIBFRAME and harmonize with other post- MARC standards. Work with specialized libraries to expand BIBFRAME’s descriptive capacity. Map MARC concepts to BIBFRAME.
