Hi,

I just started reading the RDF Primer [1] (i'm on page 43) and i'm
creating a foaf file about myself, but I have some questions (I hope
this is the right list)

In the foaf spec[2] there is an element foaf:knows in which you can
place a foaf:Person, to tell you know the other person. I have been
looking to some foaf files and there's always only one foaf:Person in
a foaf:knows like this:
<foaf:knows>
~  <foaf:Person rdf:resource="#friend1" />
</foaf:knows>
<foaf:knows>
~  <foaf:Person rdf:resource="#friend2" />
</foaf:knows>

But is it also possible to write it this way? :
<foaf:knows>
~  <rdf:Bag>
~    <foaf:Person rdf:resource="#friend1"/>
~    <foaf:Person rdf:resource="#friend2"/>
~  </rdf:Bag>
</foaf:knows>

I also saw some Foaf files where people had declared the foaf
namespace as the default namespace for the page and then defined it
again with the foaf: prefix, and they sometimes use the foaf classes
and properties without prefix and sometimes with prefix. Is there any
difference?

Is there somewhere a list of all available/known rdf vocabularies?

Kind regards,
Jeroen Budts
