.data(object) should extend the current settings not replace them.

Unless there's some logical reason as to why this can't happen, I think it would be best if calling $(selector).data(object) would extend the current set of data. That is, if I were to say: var data = {a:1, b:2, d:3}; $("#id").data("a", "apple")

.data("b", "banana") .data("c", "codfish") .data(data) .data();

The return would be {a:1, b:2, c: "codfish", d:3};

Agreed. That would also solve the problem of accidentally clobbering some other plugin's data -- unless you used the same name, of course.
