If I may interject, is the use of the "Person" and "Author" properties on your site simply to establish that the page in question represents a person and/or author? If so, probably the better solution is to use a category, instead of a property, like "[[Category:Author]]". Although SMW is meant, in part, to help avoid the use of categories, they still serve one important function in SMW-based sites, which is to establish the "class" of a page. Categories, unlike properties, have a natural concept of subclassing, which SMW's ask queries respect, so that doing a query on "[[Category:Person]]" will also get you all pages that have a category of "Author", or any other subclass of "Person".

Though I could be wrong about what you're using the properties for.

Thanks for your response. That did take care of the specific problem.
In general, however, it is an unsatisfying answer... if I have 50 subproperties in a multi-level ancestry, I lose a lot of the coolness of being able to query them with a single statement if I need to hard-code 50 statements to display that query's data...
So, feature request!
The * should behave exactly like the + in Ask queries.

I ran into a similar problem.

I had to add another line to the query, repeating the subproperty, thus:

<ask format=ol>

Now actually I did this for tables, not for ordered lists. But this
solution might work for you after all.

I'm not even sure, by the way, what operators traverse the "subproperty"
declaration, other than +.

If someone could tell me what lines in what script files define those
