* I could sacrifice relational integrity and store the expression serialized, perhaps as an AST represented in JSON or somesuch — although the rest of the data model is a rather traditional, normalized relational schema, so this is undesirable in my situation if only for consistency.

A hybrid solution could be storing the expression as a string on an entity's field *and* creating a new entity for each foreign reference. In order words, instead of storing the whole AST in the database, store it as a list on the database and the whole thing again in a field. -- Felipe.
