Linked Open Pottery

  1. 1. Linked Open Pottery: http://kerameikos.org Ethan Gruber American Numismatic Society @ewg118 Tyler Jo Smith McIntire Department of Art, University of Virginia
  2. 2. Technique ←Black Figure Red Figure→ Production Place ←Athens Apulia (South Italy)→ Period (Greek) ←Archaic Classical→ Shape ←Amphora Bell Krater→ Shape ←Amphora Krater→ Painter/Potter ←Exekias “Cotugno Painter”→ Material ←Terracotta→ Style, Iconography, Inscriptions
  3. 3. BM: http://collection.britishmuseum.org/id/person-institution/59623 Nikosthenes (potter) Getty ULAN: http://vocab.getty.edu/ulan/500115427
  4. 4. http://kerameikos.org/id/nikosthenes http://vocab.getty.edu/ulan/500115427 http://collection.britishmuseum.org/id/person-institution/59623 = (skos:exactMatch) = (skos:exactMatch) But also the same as: Dbpedia VIAF Lexicon of Greek Personal Names
  5. 5. http://kerameikos.org/id/nikosthene s rdf:type foaf:Person skos:prefLabel “Nikosthenes” (en) skos:prefLabel “Nicosthénès” (fr) Etc. skos:exactMatch <http://collection.britishmuseum.org/id/person-institution/59623> skos:exactMatch <http://dbpedia.org/resource/Nikosthenes> Etc. Hierarchical linking: skos:broader ecrm:P88i_forms_part_of Geography: geo:lat, geo:long Basic Model
  6. 6. Beazley Archive/CVA Online: http://www.beazley.ox.ac.uk/
  7. 7. Conflation of production place and historical period Beazley Thesauri: A logical starting point
  8. 8. Amphora Amphora Type A Amphora Type B
  9. 9. Screen scraping
  10. 10. Basic Classes of Typologies ● Material ● Organization (e.g., workshop) ● Period ● Person ● Place ● Shape ● Style ● Technique ● Ware ecrm:E57_Material foaf:Organization ecrm:E4_Period foaf:Person ecrm:E53_Place kon:Shape kon:Style kon:Technique kon:Ware PREFIX kon: <http://kerameikos.org/ontology#>
  11. 11. Kerameikos XRX-ish Architecture XForms, REST, SPARQL/Solr XForms processor (Orbeon) XForms instructions Fuseki Triplestore Solr Save (REST) Author/editor Web Form User (interface) HTML5: XSLT+JS+CSS VIAF DBpedia Pleiades Getty LOD Web Services External Content
  12. 12. Why XForms?  W3C standard web form specification  MVC architecture  XPath validation  Manipulate complex XML models*  Interacts with REST services (APIs) *XPath/XSLT 3.0 and XSLT 2.0 should support JSON-LD and TTL See more at http://en.wikipedia.org/wiki/XForms
  13. 13. Creating a Person
  14. 14. Creating a Shape
  15. 15. Hierarchical relationships via skos:broader
  16. 16. LGPN DBpedia http://kerameikos.org/id/exekias (303 See Other redirect to *.html) RDF Download
  17. 17. Solr faceted and fulltext search http://kerameikos.org/id/ Results also available in machine-readable Atom Query: ni?o*
  18. 18. http://kerameikos.org/ontology An RDF ontology (work in progress)
  19. 19. SPARQL endpoint and reasoner BM data BM thesauri Getty data Getty thesauri Other data Kerameikos thesaurus XForms-based Data management workflow
  20. 20. Where do we go from here? More advanced data modeling: ● Periods: 550 BC implied to be Archaic Period ● Techniques comprising techniques ● Social network analysis ● Creator roles ● Places: concept/spatial thing ● SKOS concept schemes ● Inscriptions (link to other LOD systems) ● Iconographic topic modeling ● Formalize the ontology and codify the data model But most importantly: get community buy-in
