Thread:Help talk:Reference and provenance data/Reference properties and inference

I cannot find in the manual any mention about how "inference" works with "reference" properties?

I can see that it doesn't work if i have a subproperty on the `refprop` like that:

baseprop ^   | refprop.fieldprop

For instance, even though there is a page assigning value to `fieldprop`, this search fetches nothig:

But if it's the `fieldprop` inheriting, like:

baseprop ^            | refprop.fieldprop

then inference works, but i'm getting duplicate rows where half of them are empty.

Even worse with "like" operators, where it fetches only the empty rows:


 * Is there some place where i can learn more about how they actually work?
 * E.g. some trick that can make "like" operators work?
