[Semediawiki-user] Query property values of a page

[Pierre R. <pi...@br...>]

Hello,

I'm trying to query the values of a property defined of some pages, but 
I don't know if it's possible since all the examples of the 
documentation are querying pages.
Perhaps I'm doing something wrong, here's a complete case.

I have pages about authors and books.
In the "Sample Book" page, I define the author with
[[Author::Sample Author]]
and the book types with
[[Type::Sample type]] [[Type::Second sample type]]

In the Sample Author page, I managed to get the list of his books with a 
query.
But how to get the list of Type of all his books?

Thanks a lot.
Best regards
