  • 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!

    1. 1. Linked PortableAntiquities data for#LAWDIDaniel Pettdpett@britishmuseum.orgLinks at:
    2. 2. Am I here by mistake? My stuff is British focused. But, I have Classical and geodata….You can try my β version
    3. 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. 4. Frome (Somerset) Hoard
    5. 5. Crosby Garrett (Lancashire) Helmet
    6. 6. Public recording of discovery: Big Society model? Citizen science? Archaeological destruction?
    7. 7. <objects xsi:schemaLocation="http://www.heritage- http://www.heritage- Multiple formats"> <object> <recordmetadata> <created> <createdon>2011-01-21 15:11:18</createdon> <createdby> <appellation> <name>Frank Basford</name> <identifier namespace="PAS">fbasford</identifier> </appellation> </createdby> </created> <lastupdated> <lastupdatedon>2011-01-21 17:44:00</lastupdatedon> <lastupdatedby> <appellation> <name>Frank Basford</name> <identifier namespace="PAS">fbasford</identifier> </appellation> </lastupdatedby> </lastupdated> </recordmetadata>{"recordID":"425728","finds":[{"created2":"2011 01 21","description":"<p>Afragment of a post-Medieval cast copper-alloy crotal bell (c. 1500-c. 1650).The fragment is part of the lower hemisphere and the straight edge is one sideof the sound slit.

    8. 8. Other resources – same object
    9. 9. Ringlemere gold cup
    10. 10. British Museum record
    11. 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. 12. OAI – PMH: UK databases
    13. 13. Linked data Who might our audience be? Low uptake by consumers Big impact for web resources Are we reinventing the wheel?
    14. 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. 15. Am I doing this right? Doubts: Am I doing it right?
    16. 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. 17. Someone arrived 6 weeks early
    18. 18. Read Beck’s post here:
    19. 19. Geonames/ Geoplanet Interoperability/ enrichmentdbpedia PAS AmazonPleiades Flickr Nomisma
    20. 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. 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. 22. Enriched data via dbPedia {Prefixes omitted for space} SELECT * WHERE { ?emperor foaf:page<> . 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. FILTER langMatches( lang(?abstract), "en") } LIMIT 1 Keep Calm riffed image: in-code-rest-php-and-json-tutorial/
    23. 23. for example
    24. 24. Implemented the AWLD magic script
    25. 25. Friend of a friend implementationExample at:

    27. 27. Geodata entity extraction Using YQL: Parse body of text Extract all geo entities Can be concorded to geonames ->pleiades How to:
    28. 28. Linked geo data
    29. 29. Power of WOEID
    30. 30. Entity extraction One can extract personal names, places, concepts, relations, positions via OpenCalais Try this via Paste in text and submit for analysis I do this via curl in a php script per page
    31. 31. Objects referencing place: The Staffordshire Moorlands trullaThis is a list of four forts located at the western end of Hadrians Wall;Bowness (MAIS), Drumburgh (COGGABATA), Stanwix(UXELODUNUM) and Castlesteads (CAMMOGLANNA). itincorporates the name of an individual, AELIUS DRACO and a furtherplace-name, RIGOREVALI.
