_refs

Returns all of the Things that use this Property to point to this Thing. -- Function

THING -> PROPERTY._refs -> REFERRING THINGS Say that my Space is listing my CD collection. I have a Model Album for individual discs, and Model Artist for performers. Album has a Property Artists, which is a Set of Links to Artist -- basically, the list of performers on this particular CD.

In this case, Artist is likely to want to say something like:

[[Artists._refs -> _bulleted]]

That is, based on the Artist we're looking at (which is always the initial Context passed into a QL Expression), get all the Things that refer to this Artist using the Artists Property, and display them as a bullet list.

This method is enormously useful -- most Models that get pointed to like this will probably want to use it.

Note that this always returns a List, since any number of Things could be pointing to this.

Note: _refs only produces the "hard" references, through Thing Properties. Most of the time, you should use _allRefs instead -- that includes references through Tags as well.
