I also think classes do not have the importance thy deserve in Wikidata
yet. Everything is centered around properties and the property creation
right who entails the editorial process.
This might change in the future depnding on how Queries are implemented :)
I'd love that we could use Queries items in «instance of» sand «subclass
of» statements and that we could indeed verify that any instance of the
subclass is also an instance of the superclass with the help of queries :)

Hoi,
The main point I get is that DBpedia is used and usable
If anything all the rest are things where Wikidata has its problems in
equal measure. As I read it, Wikidata has a bigger community with some
people doing a lot of muddling with the most wonderful subclasses and
hierarchy that are often unknown by others and happily ignored.Come to
think of it, When the data quality is compared, I doubt Wikidata will be so
great because there is so much just not there..
Thanks,
GerardM

Hi all,
Vladimir Alexiev has published an interesting post on issues he
encountered when using DBpedia at OntoText, drawing many comparisons to
Wikidata [1]. While this post praises the practices of Wikidata in several
places, I think there are a few important insights for Wikidata there as
well. There are certainly points where Wikidata is running into similar
issues (if you have had a look at our class hierarchy recently, you know
what I mean). Even in the cases where we are doing good, it might be
valuable to obtain some feedback and reconfirmation from another
perspective.
Cheers,
Markus
