Hello all,
I am playing around with properties at the moment, especially filtering out a certain kind of properties.
So I wondered if it wouldn't be a nice thing, if properties were classified in some way.
Example: (Numbering is just for readability and does not hold any semantics) P… is the placeholder for the actual property-Id, did not want to look them all up
1) Relations 1a) Mathematical relations 1b) Relations in human interaction 1b1) Social relation 1b1a) P… (is employee of) 1b1b) P… (is heir to) 1b2) Biological relation 1b2a) P… (brother of) 1b2a) P… (sister of) … 2) External IDs …
and so on, I think you get the idea.
Has something like this bees discussed before?
Cheers, Fredo
See Wikidata:Requests_for_comment/How_to_classify_items:_lots_of_specific_type_properties_or_a_few_generic_ones%3F#Subproperty_of
for a discussion of a 'subproperty' relation. where a property can have a statement that it is a 'subproperty' of another property and the query engine could search on a property, including all of it's subproperties.

We can't at the moment make statements on properties, nor use properties as value in statement, so this is a little premature. It's on the devs high priority list , amongst queries though.
Atm, properties classification is not really something we do well. We got a list of properties wikipage and some subpages, some Wikiprojects regroups the properties of their fields, some of us tried to associate a list of properties to a class item, that's pretty much where we are.

I think the best scheme I've seen like this yet is at
https://developers.google.com/freebase/v1/search-metaschema
In the RDF model it is easy to make statements about predicates
?p a :SocialRelation .
the key is that it is multi-dimensional so probably a given predicate will be a member of a few different categories scattered across the system.
