Referring to the NIST classification of semantic relations, general affiliation
is a different relation than part-of. That's why conflating them is not the
best idea.
But this is a minor issue in that context. I am wondering if there is any list
of properties for beginners, that should not be
Back to the original discussion...and summary...
Anyways, thanks to all for summing up the current state of the Properties
on properties which is the 1st step for the Rules enforcement and that
will offer similar capabilities that Freebase had with Incompatible Types.
Also I feel more
Country (p17) should be used for a general affiliation. Dublin has a
general affiliation with Ireland.
On the other hand City of Dublin is in the administrative territorial
entity Dublin region which is in the administrative territorial entity
Republic of Ireland which is on the geographical

While property re-use is desirable in general, we need to make some
basic distinctions. The realm of geographic relations (a special kind of
part-whole relations) is particularly clear and specific, and it would
be worthwhile to distinguish them from more vague notions of
Hi,
the discussion regarding the properties in Wikidata is very interesting.
However I have doubts if leaving the country (P17) property as it is, is a good
idea.
The difference between Dublin country: Ireland, and U2 country: Ireland, is not
superficial, but in both cases we have to do with
First:
A band is an organisation, not a person.
Second
P17 is deliberately a bit ambiguous so it can be used for those cases where
we don't have specific info. We also have specific properties for those
cases where we have specific info.

I like the property-centric approach of wikidata, but is there a notion of
subproperties for contextual refinement? I only found this:

Yes that is all there is. For a usage example see

You used the English word associated. That's great. Then I would
propose to expand the definition of P17 just a bit to add that.
P17 Country - sovereign state of this item ... to ... sovereign state
ASSOCIATED with this item
Then you save the world. =)

Freebase has mutexes that store incompatible type information.
For instance, in Wikidata I noticed on the U2 band topic, that they have
statements of:
P17 Country - sovereign state of this item.

formed.

Dear Thad,
The second part of your email has good points in it, too. As you say,
one must allow for adjustments in the intended meaning of a property in
real life, and adjusting too much could be dangerous. The method you

Right, Freebase would not stick a Property called Country right on an
instance of a Music Band. We would put Country under the Musical Group
type, and give it a better definition like The nation or territory that
this item originated from.
