1. A Semantic Multimedia Web: Create, Annotate, Present and Share your Media Raphaël Troncy, < [email_address] > CWI, Interactive Information Access

8. image.jpg has for creator Raphael and depicts the elephant Ganesh

9. image.jpg has for creator Raphael image.jpg depicts the elephant Ganesh

10. ( image.jpg , creator , Raphael ) ( image.jpg , depicts , Elephant Ganesh ) ( subject , predicate , object )

19. nodes RDF allows blank

20. anonymous a resource may be i.e. not identified by a URI and noted _: xyz

21. e.g., there exists an image about Ganesh

22. http://comm.semanticweb.org/core#Image rdf:type _:x http://xmlns.org/foaf/0.1/#depicts &quot;Ganesh&quot;

23. break blank nodes the graph, they cannot be reused

24. name your resources and reuse existing names as much as possible

29. open-world assumption as opposed to the closed world assumption of classical systems

30. in short: the absence of a triple is not significant

33. if you have no other triples giving authors it does not mean they are not true .

39. DOCUMENT REPORT

41. CREATOR AUTHOR

43. PERSON MAN MALE

47. but looks like object programming,

70. Differential Principles Role Actor Director P3 : difference between the sibling nodes P4 : common property shared by the sibling nodes Plays in the movie Directs the movie P1: property with parent node (being a role of a human being) P2 : difference with parent node
