Create your first relation

Now we made a node about ourself, so let's attach something to it!

I want for example to add which languages I speak. So I will create some nodes for the languages I speak:

  @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
  @prefix skos: <http://www.w3.org/2004/02/skos/core#> .
  @prefix qa: <http://qanswer.eu/> .

  qa:node2 rdfs:label "English" .
  qa:node3 rdfs:label "French" .
  qa:node4 rdfs:label "German" .
  qa:node5 rdfs:label "Italian" .

and a new property to express which languages I speak:

  qa:language rdfs:label "speaks language" .
  qa:language skos:altLabel "speak" .
  qa:language skos:altLabel "language" .

and use it:

  qa:node1 qa:language qa:node2 .
  qa:node1 qa:language qa:node3 .
  qa:node1 qa:language qa:node4 .
  qa:node1 qa:language qa:node5 .

So the last triples encode that "QAnswer speaks English, French, German and Italian".

info

If you were really careful you could have thought: This property looks like a node?!?!

Yes it is true, the only difference that makes qa:language a property is that we put it between two nodes.

What can we ask now?

Question 1

Question 2

Question 3

Question 4

Ok, I guess now it should be clear how to add more information about yourself .... try out your creativity!

This is how far we got for now:

  @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
  @prefix skos: <http://www.w3.org/2004/02/skos/core#> .
  @prefix qa: <http://qanswer.eu/> .

  #Making our first node
  qa:node1 rdfs:label "QAnswer" .
  qa:node1 skos:altLabel "QAnswer KG" .
  qa:node1 skos:altLabel "QA" .
  qa:node1 skos:altLabel "you" .

  #Adding some additional nodes
  qa:node2 rdfs:label "English" .
  qa:node3 rdfs:label "French" .
  qa:node4 rdfs:label "German" .
  qa:node5 rdfs:label "Italian" .

  #Creating our first property
  qa:language rdfs:label "speaks language" .
  qa:language skos:altLabel "speak" .
  qa:language skos:altLabel "language" .

  #Saying that QAnswer speaks English, Franch, German and Italian
  qa:node1 qa:language qa:node2 .
  qa:node1 qa:language qa:node3 .
  qa:node1 qa:language qa:node4 .
  qa:node1 qa:language qa:node5 .
