Who and what are we working on? • Began with access to online collec5ons via website [2010] • Extended XML data provider, [2011] in use by:
• In 2012 began crea5ng unified LOD based on CIDOC-‐CRM and other (SKOS, RDFS, etc.) ontologies with:

Is our Linked Open Data truly open?
“Linked Open Data, end-‐users, and applica5ons” by Lec Maj @ AAC LOD 2013
What is CORS about? CORS is a specifica5on that enables truly open access across domain boundaries. hkp://www.w3.org/wiki/CORS_Enabled Simply put, anyone can write any apps to get at our data (inc. JavaScript, JQuery, JSON, etc.)

Needed tools
“Linked Open Data, end-‐users, and applica5ons” by Lec Maj @ AAC LOD 2013
• Visual drag-‐and-‐drop ontology mapping tools similar to Yahoo Pipes
Needed tools
“Linked Open Data, end-‐users, and applica5ons” by Lec Maj @ AAC LOD 2013
• Data verifica5on from crowd-‐sourcing efforts as in curators or Mechanical Turk or Facebook
• Replace the tradi5onal Collec5ons Management System with web based interac5ve tools
• Embrace new tools as Drupal, Wordpress, etc. for cataloging
What are researchers looking for? • What are all objects across the globe
produced in reference to John Constable? • Who did John Constable inspire? • What objects were created along what point
in 5me and place on the grand tour? • What related types of objects are in
existence • What drawings were created and owned by
Paul Sandby (analysis of image markings to iden5fy marks on them)
• History map of ownership migra5on for Sandby’s drawings
• Compare composi5ons of water colors to other objects to help speculate ar5s5c models (how was the work influenced, how it is treated by various ar5sts)
