Year 3 Geography class last Tuesday• 347 users accessed this resource last month
Why?• Improved search ranking• Communities of practice• Feedback to publishers• Feedback to jurisdictions• Discovery across portals• Discovery outside portals
History• Initially defined 2010• National Science Digital Library, XSD• Learning Registry, 2011• Several US participants, UK, EU• Moving towards LRMI (Schema.org)
• ADL, 2012 (TinCan)• Specifications based on ActivityStreams• Same overall structure, differ in some
attributes and level of strictness
Web 2.0 Standard• Represented in JSON• Lightweight (to deploy & to consume)• Open-ended• No managed vocabularies• Key-value pairs• A few fixed structural keys• Statements: predicates• actor, verb, object (the resource), context• “(John) (liked) (War and Peace) (on
Facebook)”
