Transcript

  • 1. IIWeb 3.0explained with a stamp(English version)Part I: the basicsPart II: techniques
  • 2. A presentation from: Freek Bijl(Dutch) blog: Bijlbrand.nl
  • 3. Web 3.0 - the semantic web - is about the meaning of data.
  • 4. This is a stamp In 1980 you could buy this stamp for 1 cent Now it’s worth 3 euros This stamp is from the United Kingdom This stamp is used between 1978 - 1981 The picture on the stamp is a PO BoxThis stamp is designed by John Bryan Dunmore
  • 5. Why do we wantto add meaning to data ?
  • 6. When a computer understands what data means, it can do intelligent search,reasoning and combining.
  • 7. This makes our live more easy.
  • 8. The next technologies are used to make amore semantic web…
  • 9. RDF XML URISPARQL XDI XRISWRL XFN OWL API OAUTH
  • 10. !Complicated
  • 11. An explanation with a stamp collection.
  • 12. Meaning is about understanding. Tounderstand we need alanguage. A language starts with words.
  • 13. Things mean something in words. Online, we describe things with XML.
  • 14. This is my stamp collectionThe first stamp is called “Red dragon”and is from China. It was made in theyear: 1984.The second stamp is called “PO Box”and is from England. It was made in theyear: 1992.< .. etc >
  • 15. =
  • 16. <?xml version="1.0" encoding="ISO-8859-1"?><collection name=”My stamp collection"> <stamp> <title>Red dragon</title> <country>China</country> <year>1984</year> </stamp> <stamp> <title>PO Box</title> <country>England</country> <year>1992</year> </stamp></collection>
  • 17. We can’t understand words alone. We also needgrammar. Online grammar is RDF (Resource Description Framework).
  • 18. This stamp is from England.
  • 19. predicate objectsubject This stamp is from England.
  • 20. With RDF Scheme we can defineconcepts and make simple relations between them.
  • 21. This stamp isfrom England, hence from Europe.
  • 22. But, RDF scheme is limited. A language needs more expression and logic to make good reasoning possible. That’s why OWL (The Web Ontology Language) was invented.
  • 23. Finally, to reason you need rules.
  • 24. I got this stampfrom my uncle.
  • 25. son of brotherI mother or fatherThe rule for callingsomeone my uncle is thatone of my parents has abrother.
  • 26. Rules are formulatedin SWRL (SemanticWeb Rule Language).
  • 27. <ruleml:imp><ruleml:_rlab ruleml:href="#example1"/><ruleml:_body> <swrlx:individualPropertyAtom swrlx:property="hasParent"> <ruleml:var>x1</ruleml:var> <ruleml:var>x2</ruleml:var> </swrlx:individualPropertyAtom> <swrlx:individualPropertyAtom swrlx:property="hasBrother"> <ruleml:var>x2</ruleml:var> <ruleml:var>x3</ruleml:var> </swrlx:individualPropertyAtom></ruleml:_body><ruleml:_head> <swrlx:individualPropertyAtom swrlx:property="hasUncle"> <ruleml:var>x1</ruleml:var> <ruleml:var>x3</ruleml:var> </swrlx:individualPropertyAtom></ruleml:_head></ruleml:imp>
  • 28. So,
  • 29. Words in XMLGrammar in RDF (scheme) and OWLRules in SWRL
  • 30. There are a lot ofthings, that can be described using standard formats.
  • 31. For example: contact information.
  • 32. hCard > contactshCalendar > eventshReview > reviewshResume > resumesXFN > social networks (relation= a friend or colleague)These things are described with microformats.
  • 33. Suppose, I want to search for a specific stamp.
  • 34. “I want all the red stamps, designed in Europe, but used in the U.S.A., between 1980 and 1990”
  • 35. We can useSPARQL (Protocol and RDF Query Language).
  • 36. Because the web isdecentralized and data is in many places, not only language is important.Exchange of data betweendifferent machines is key.
  • 37. A database with stampsA database with countriesA database with colorsA database with stamp traders
  • 38. To make a connection a machine needs a source. For this, we use resource identifiers. Best knownresource identifier is the URI (which consists of a name (urn) and a location (url)).
  • 39. Because URI’s haveinternational limitations and the need for data-exchangebetween machines is rapidlygrowing there is a successor: XRI (Extensible Resource Identifier)
  • 40. There is a standard for sharing, linking and synchronizing data.This standard is called XDI (XRI Data Interchange).
  • 41. With all this I am capable of using thepower of all differentdata resources on the web.
  • 42. But…
  • 43. Data is protected. We needconsent and a key to gain acces.
  • 44. The key to certain data is described in an API (anapplication programming interface).
  • 45. An open standard foraccessing (authentication) the API is OAuth.
  • 46. So,
  • 47. RDF XML URISPARQL XDI XRISWRL XFN OWL API OAUTH
  • 48. … are now words with a meaning for you !
