Library Models and Standards and Their Availability in the Semantic Web Workshop LIDA 2012 Exposing heterogeneous data more efficiently, using Semantic Web tools data. bnf. fr Françoise Leresche Bibliothèque nationale de France Bibliographic and Digital Information Department Standards and Models Unit
Bibliothèque nationale de France o Millions of resources n of any kind (books, scores, maps, still images, audiovisual materials…) n published items / manuscripts and archival resources o Made Web available through digitization
Different logics o Published resources n Bibliographic description (ISBD) and MARC format o Archival resources n Archival description (tree structure) and XML -EAD format o Digitized resources n Simple Dublin Core format
Catalogues o Bn. F Catalogue Général n 15 millions of bibliographic records n Legal deposit of French edition o Bn. F Archives et Manuscrits (BAM) n Dozens of thousands of manuscripts and archival resources n Mediaeval manuscripts, authors' archives o Gallica n 1, 5 million of digital objects n The largest digital library in the French-speaking world
Resources o Often hidden in the "Deep Web, " i. e. : n buried in catalogues n scattered among various addresses
Web practices o Less people come in through home pages n they access site pages directly o Keyword research n associated with final content e. g. : a book title o Navigating links n on blogs, sites, networks
Organizing information o Gathering contents, links, and services n Pages for human reading n Data for machine reading o Some tools are at hand: n Authority records n Description standards n Perennial identifiers o The project
The project o Data clustering n Published resources n Archival resources n Digital resources o About authors, works, and topics o Providing n HTML pages n RDF structured, open, W 3 C standards compliant data
For what purposes? o To propose services n Beyond warehouses n For any audience o To open data n and make it free o To provide reliable links
The project Links for authors, works, and topics n Links to books, manuscripts, images… o disseminated to any audience o through user-friendly HTML pages
HTML pages o In order to: n provide content n create links to resources n lead users to services
HTML pages o Clustering on one page o all the information relating to n an author n a work n a topic o from heterogeneous formats o using Semantic Web technologies
Semantic Web o Combining a traditional Web interface with a Semantic web approach n Gathering information around a concept n In addition to resources, an address and meaningful machine-usable data n RDF chosen as resource description framework
Elaboration on data o Relying on n authority records, n and persistent identifiers o Period of reflection on standards n Defining a model n Selecting vocabularies o Data alignment and integration
How does it work? Digitized resources Human-friendly Web pages Bn. F Archives et Manuscrits Clustering - Alignment Bn. F Catalogue général Machine-friendly data
Functional principles Web Interface Linked Data Publication - control Page concepts leading to Clustering - Aligning Other libraries Extracting - Transforming Other resources Autres sources Wikipedia, etc. Wikipedia. Catalogue général Bn. F Archives & manuscrits Gallica Virtual n exhibitions Mandragore
Authority records o ID card for an entity (person, corporate body, work…) n n n the preferred form variant forms (references) notes sources links to other records an identifier (at the Bn. F, ARK identifier)
Authority record for a work associated with an author Link to the authority record for the creator of the work Link to bibliographic records Preferred access point title of work Links to other works (whole/part relationships) Persistent identifier
Persistent identifiers o Persistent identifier n to recognize a resource n uniquely n on the long term o Stable Reference n Naming n Finding n Citing o Two objectives n Access n Preservation
Persistent identifiers: ARK http: //catalogue. bnf. fr/ark: /12148/cb 11992684 q/UNIMARC Qualifier Label Name Mapping Authority Host (NMAH) (interpreted by the Name Mapping Authority) Name (assigned by the Name Assigning Authority) Name Assigning Authority Number (NAAN)
FRBR model Creation (at the top level of abstraction) Work Expression Manifestation e. g. : Tales of the Grotesque and Arabesque, E. A. Poe Version under which a Work is available (type of content, language, contribution) e. g. : French translation by Baudelaire Publication (production of the book: publisher, printer) e. g. : Ed. Paris : M. Lévy frères, 1875. xxxi-330 p. Physical copy Item e. g. : digitized copy ark: /12148/bpt 6 k 2029183
Why FRBR? o Organized display n of the various versions of a Work n of the various productions of a Person o Better matches to Web users' various queries
Why FRBR? o To interrelate persons and works at the right level of contribution n Creator of a work o author, composer… n Contributor to an edition o translator, author of a foreword… n Producer of a publication o publisher, printer, distributor n Name associated with a single exemplar o owner, annotator…
Vocabularies o No "records, " only data o for concepts o for authors o for works SKOS FOAF RDA n implementation of the FRBR model http: //www. rdatoolkit. org/backgroundfiles/Relationships Overview_10_9_09. pdf n definition of the roles associated with the various types of contribution

Benefits o Visibility n Being on users' path n Finding resources without knowing of them o Knowledge enhancement n Simple pages and large audience n Creating links n Enabling data reuse
Benefits o For the Bn. F n Experimentation o FRBRizing catalogue records o Future developments for the catalogue o New mode of disseminating bibliographic information n Showing up in the Linked Data world
Presence in the Linked Data cloud http: //richard. cyganiak. de/2007/10/lod-datasets_2011 -09 -19_colored. html
