2. "Saluting the Flag" by Israel Defense Forces Data janitors, we should feel the same about our data as the army does about our country
3. XKCD: Devotion to Duty As data janitors we should feel as close to the data as a sysadmin to a server’s uptime Killing for the data
4. ELIS - Multimedia Lab Good data, bad data?
5. ELIS - Multimedia Lab Linked Data what? Because it’s impossible to store all the world’s knowledge on 1 machine…
6. ELIS - Multimedia Lab An example Earth is the same as The world Earth is a Planet The world has population 7.152 billion Machine 1 Machine 2 Machine 3 World Wide Web
7. World Wide Web ELIS - Multimedia Lab An example Earth is the same as The world Earth is a Planet The world has population 7.152 billion Machine 1 Machine 2 Machine 3
8. ELIS - Multimedia Lab name type same as Population Earth Planet The World 7.125*109 The World Planet Earth 7.125*109 { “Earth” : { “type” : “Planet”, “same as” : “The World”, “population” : “7.125*109” } } <Earth> <type>Planet</type> <sameas>The World</sameas> <population>7.125*109</population> </Earth> <Earth> <type> <Planet> ; <sameas> “The World” ; <population> “7.125*109” . Table / CSV / Spreadsheet JSON XML triples
9. ELIS - Multimedia Lab Problem Earth is a Planet How do we make sure “Earth” means planet Earth on another machine as well? semantic interoperability and the relation “is a”? and “Planet”?
10. ELIS - Multimedia Lab Solution? http://dbpedia.org/resource/Earth http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://dbpedia.org/ontology/Planet Uniform Resource Identifiers
11. ELIS - Multimedia Lab Solution! Linked Open Data cloud
12. ELIS - Multimedia Lab For example DBPedia: wikipedia in triples Earth on dbpedia: http://dbpedia.org/resource/Earth What other planets are there on dbpedia? http://data.linkeddatafragments.org/dbpedia?subject=&predicate=%3Chttp%3A%2F%2Fwww.w3.org%2F1999%2F02% 2F22-rdf-syntax-ns%23type%3E&object=%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2FPlanet%3E By asking different servers on the Web, different basic questions, really difficult questions can be answered
13. ELIS - Multimedia Lab Problem How do we know what URIs to use?
14. ELIS - Multimedia Lab Solution Vocabularies, thesauri, ... OSLO 2.0
15. ELIS - Multimedia Lab Components OSLO
16. ELIS - Multimedia Lab URI Strategy http://www.opendataforum.info/Docs/URI_strategie_versie2.pdf
17. ELIS - Multimedia Lab Vocabularium
18. OSLO | Open Standaarden voor Lokale Overheden authentieke bronnen lokale verrijking
