Thanks Daniel, I thought that may be off the cards for the time being. Good to know it's possible though :-) On 3 Dec 2014 22:32, "Daniel Kinzler" daniel.kinzler@wikimedia.de wrote:

That's fantastic news! :) Just curious... when statements linking to
other
properties has been implemented, will that include the ability to start
defining
a class tree for the properties? It would be amazing if you could one
day run
queries like "all items with any subclass of location set to Berlin",
getting
all people born in there, items located there etc with a single simple
instruction.
You can define such "sub-property" relationships, yes (but please don't use "subclass" for this, properties are not classes).
However, using such relationships for queries is a lot harder. They essentially add an entire dimension of data to process. It's possible, and would be cool, but it's not easy, so don't hold your breath...
