In addition to the classic links to an object like a person or a place that can be made in a note, the links could refer to a filter of the category in question, when clicked on, it is not the record that would open but the corresponding filtered view.
The interest of such links, in addition to being dynamic, could for example be to make a note telling the history of a place evoking families who founded it, and the filter could return the bearers of this particular family name in this particular place in Persons view. Not just one person but all of them at once.
I suppose we can imagine other examples of use cases.
