Marcus smith – Linked Data Vocabularies for Heritage Data

  1. 1. Sigurdsristningen, Ramsundsberget, Sö 101 CC BY Bengt A. Lundberg, Riksantikvarieämbetet Linked Data Vocabularies for Heritage Data Marcus Smith, Swedish National Heritage Board
  2. 2. Linked Data Vocabularies • There are lots of existing vocabularies published as linked data – chances are your domain is already covered • If there are existing vocabularies you can apply or map to, you should! • If not, you can create your own, or publish your existing vocabulary as linked data En pojke i golfbyxor, pullover och skärmmössa äter glass vid en cykel CC BY-NC-ND Gunnar Lundh, Nordiska Museet
  3. 3. From Strings to Things Step 1: Switch from a data dictionary of permitted terms to a list of ids • This decouples your ids from your values – good data hygiene • You can then associate multiple lookup values and attributes with each concept En kvinna demonstrerar Frösöstenen, J RS1928;66 Bengt Wellert, Östersund, Stiftelsen Jamtli
  4. 4. From Strings to Things For example: • Terms in multiple languages • Preferred and alternate terms • Scope notes, and other attributes • Relations to other terms, e.g. broader/narrower, identities Now you have a structured vocabulary! Igelkottar CC BY-NC Hilding Mickelsson, Hälsinglands museum
  5. 5. From Strings to Things Step 2: Make those ids resolvable IRIs • Public, permanent, dereferenceable, machine-readable ids • This allows lets you and others refer to them as linked data • Often used as e.g. dcterms:type, dcterms:subject, rdf:type, etc • A simple list of RDFS terms with basic Dublin Core attributes is a good start Princessan Margrethe av Danmark deltar I arkeologiska utgrävningar vid San Giovenale I Italien. Här ses hon framför en kammargrav. CC BY-NC-ND Nordiska Museet
  6. 6. From Strings to Things SKOS (Simple Knowledge Organisation System) • For a well-structured linked data vocabulary, use SKOS! • Relate terms to one another within a vocabulary • Relate to similar/equivalent terms in other vocabularies • SKOS is also a great introduction to LOD Ungräven grunnar på nya hyss I skogen CC BY-NC Hilding Mickelsson, Hälsinglands museum
  7. 7. Tools for Linked Data Vocabularies • Ariadne – e.g. iDAI vocabulary tool https://portal.ariadne-infrastructure.eu/services https://archwort.dainst.org/de/vocab/ • SKOSify – https://seco.cs.aalto.fi/tools/skosify/ • SpreadSKOS – http://siskos.herokuapp.com/ • STELLAR/STAR/SENESCHAL/STE LETO – https://hypermedia.research.southwales.ac.uk/kos/ • ASKOSI – http://www.askosi.org/ Sigrid Olsson, Karlstads styvaste pistolskytt CC BY-NC-SA Karlstads Tidningen, Värmlands museum
  8. 8. Linked Data Vocabularies for Heritage Data Use existing vocabularies/authorities! • LoC Subject Headings – http://id.loc.gov/authorities/subjects • Getty AAT – http://vocab.getty.edu/ Art and Architecture Thesaurus – styles, periods, object types etc • PeriodO – https://perio.do/ International gazetteer of periods and chronologies Inmatning av rundata CC BY Runverket, Riksantikvarieämbetet
  9. 9. Linked Data Vocabularies for Heritage Data • Heritage Data – https://www.heritagedata.org/ Monuments types, chronologies, artefact types, techniques etc from UK heritage agencies • Creative Commons and RightsStatements.org – http://creativecommons.org/ , http://rightsstatements.org/ Katt CC BY-NC Blekinge Museum
  10. 10. Linked Data Vocabularies for Heritage Data • VIAF – http://www.viaf.org/ For authors, bibliographic data • Finto – https://finto.fi/ Finnish vocabulary and ontology service • Wikidata – http://www.wikidata.org/ Great as a node for links; see https://pro.europeana.eu/page/get-your-vocabularies- in-wikidata En ring av guld från Slöingeboplatsen CC BY Klas Höglund, Statens historiska museum
  11. 11. In summary • If there are existing LOD vocabularies for your domain, use them! • If there aren’t, make and publish your own! • Use IRIs as identifiers in your vocabularies • Structure and publish them as SKOS RDF Vg 169 Svedjorna, Södra Ving PD Riksantikvarieämbetet
