You can create some pretty awesome messes even without OWL:
# An rdf:List that loops around...
<#mylist> a rdf:List ;
rdf:first <#Alice> ;
rdf:next <#mylist> .
# A looping, branching mess...
<#anotherlist> a rdf:List ;
rdf:first <#anotherlist> ;
rdf:next <#anotherlist> .
They might be messy, but they are *possible* structures using pointers,
which is what the RDF vocabulary describes. Its just about impossible
to guarantee that messes can't happen when all you are doing is
describing structures in an open-world setting. But I think the cure is
to stop thinking that possible-messes are a problem to be solved. So,
there is dung in the road. Walk round it.
Could we also apply that to the 'subjects as literals' general
discussion that's going on then?
For example I've heard people saying that it encourages bad 'linked
data' practise by using examples like { 'London' a x:Place } - whereas
I'd immediately counter with { x:London a 'Place' }.
Surely all of the subjects as literals arguments can be countered with
'walk round it', and further good practise could be aided by a few
simple notes on best practise for linked data etc.
Best,
