We show that multiparticle states can be viewed algebraically as specifying relations between reference frames associated with particle degrees of freedom. Building on work by Gour and Spekkens on quantum reference frames, we propose a characterization of contextuality as information compression related to identifying reference frames of particular degrees of freedom. As a simple example, we show how bipartite entanglement arises from product states subject to an identification of rotational reference frames.
