  1. Rappresentare i soggetti nel modello IFLA LRM Pino Buizza ISKOI Firenze, 11 aprile 2019Sala Galileo della BNCF

  2. No semantics Senza semantica • Why? Perché? • What are wegaining and losing? Che giova, che si perde? • Whatwouldwelike? Desiderata • (Im)possible? (Im)possibile? Pino Buizza. I soggetti in IFLA LRM

  3. Senza semantica = No semantics IFLA LibraryReferenceModel • “we now finally have a complete model of the bibliographic universe” MajaŽumer, in ISKO Encyclopedia • butsemanticsismissing • workhasassubjectres / resissubjectofwork • thema (FRSAD)  res (LRM) • “to avoid the implicit restriction to the subject relationship” DELETED: • aboutness, ofness and isness • semanticrelationshipsthema – thema “specificrefinementswouldbedefinedtocarry more precise semantics” “the specific thesaural relationships between res that serve as subjects would be defined as refinements of the top relationship” Pino Buizza. I soggetti in IFLA LRM

  4. Tracce di semantica Tracesofsemantics • nomenis part ofnomen Measlesis part ofMeasles/epidemiology • resisassociatedwithplace • resisassociatedwithtime-span MozartisassociatedwithSalzburg … with1756 but: Mozart – Naples – 1770 • IFLA LRM: può contenere tracce di semantica. // In: Bibelot, 24,3(2018), p. 52-56 • https://riviste.aib.it/index.php/bibelot/article/view/11853 Pino Buizza. I soggetti in IFLA LRM

  5. Perché?Why? • History. Low traditionofinternational and inter-system cooperation in indexing • Today. Toodifferentindexingsystems, differentgranularity • Target. High levelmodel • No lowestcomondenominator? Pino Buizza. I soggetti in IFLA LRM

  6. Che giova, che si perde?What are wegaining and losing? • Gained: Freedomto design systems Opportunitytoimplement ‘specificrefinements’ • Lost: Semanticrelationships (in anEntity-Relationshipmodel!) Syntacticrelationships (in anEntity-Relationshipmodel!) Thema Pino Buizza. I soggetti in IFLA LRM

  7. Desidetata. PreludioWhatwouldwelike? prelude In subjectrelationshipswehaveconcepts and individualentities alone: • Vocalmusic • Interpretation • Wolfgang Amadeus Mozart • Naples and theircombinations, in specificworks, in pre-coordinatedsystems • Interpretation + Vocalmusic • Wolfgang Amadeus Mozart + Naples • Wolfgang Amadeus Mozart + Vocalmusic and theircombinations, in specificworks, in post-coordinatedsystems • #Interpretation#Vocalmusic • #Wolfgang Amadeus Mozart #Naples • #Wolfgang Amadeus Mozart #Vocalmusic Pino Buizza. I soggetti in IFLA LRM

  8. Relazioni sintatticheSyntacticrelationships • Let’shavetwoentitiesforsubjectrelationships in the model: resforconcepts and individualentities alone themafortheircombination* • and the syntacticrelationship “resiscomponentofthema/ themahasascomponentres”* * optional, notapplicableforpost-coordinatedsystems.
