  • Major aggregation is via OAI
  • Must remember this script can only add the linkage if the hyperlinks appear within your html already. It does not auto inject, now that would be cool…..
  • FOAF (an acronym of Friend of a friend) is a machine-readable ontology describing persons, their activities and their relations to other people and objects.
  • No one has mentioned the rdf cookbook! http://bit.ly/KPSJef

  • 2. Am I here by mistake? My stuff is British focused. But, I have Classical and geodata….You can try my β version http://beta.finds.org.uk
  • 3. The Portable Antiquities Scheme First database online in 2001 The HLF funded next iteration at £150K Holds data for over 750,000 objects Since 2006 developed entirely by speaker Huge open source cms for small finds Most recent iteration cost £48 + salary Online audience has grown 63% in last year Over ½ million visitors in 2012 Annual budget of £4,000 for web production Resource for a niche audience Big stories get huge attention spike Over 1 million pages of html content andsimilar machine readable
  • 4. Frome (Somerset) Hoard
  • 5. Crosby Garrett (Lancashire) Helmet
  • 6. Public recording of discovery: Big Society model? Citizen science? Archaeological destruction?

  • 9. Ringlemere gold cup
  • 10. British Museum record
  • 11. BM collection page• It exists on the endpoint• But I can’t find it….• Challenge for Dominic to find it by end of talk
  • 12. OAI – PMH: UK databases
  • 13. Linked data Who might our audience be? Low uptake by consumers Big impact for web resources Are we reinventing the wheel?
  • 14. Barriers for implementation -producers Knowledge Projects to emulate Staff resource Time Funding Too many ontologies to choose from…. Lack of management buy-in and vision
  • 15. Am I doing this right? Doubts: Am I doing it right?
  • 16. What I had hoped to show you: Finished website Attestations to Pleiades Partial linking to Nomisma RDFa through out all pages Content negotiation
  • 17. Someone arrived 6 weeks early
  • 18. Read Beck’s post here: http://bit.ly/KPTTXf
  • 19. Geonames/ Geoplanet Interoperability/ enrichmentdbpedia PAS AmazonPleiades Flickr Nomisma
  • 20. What aspects can I link to? People Places – eg Pleiades places Time Events Citations/ references Museum objects eg all BM/ANS denarii Books
  • 21. Enriched by Amazon via ISBN I use the affiliate programme in the vain hope of us making some cash! I could of course link to open bibliographic projects.
  • 22. Enriched data via dbPedia {Prefixes omitted for space} SELECT * WHERE { ?emperor foaf:page<http://en.wikipedia.org/wiki/Augustus> . OPTIONAL {?emperor dbpedia-owl:abstract ?abstract} . OPTIONAL {? emperor foaf:depiction ?depiction} . OPTIONAL {? emperor dbpedia-owl:thumbnail ?thumb} . OPTIONAL {? emperor dbpedia2:imgw ?imgw} . ?emperor foaf:page ?page.
