definitions of queries vs. rules

In the charter terms [1], I make the bold statement that rules are
composed of queries and assertions. This is intended to clarify why
both communities have been inducted into the same list. In
implementing algae [2], I used the variables bindings from a query to
compose assertions. Does this match the experience of others?
