{title2=$(\Lambda V,d)$}
A free graded-commutative rational <differential graded algebra> with decomposable differentials and a <quasi-isomorphism> to the rational polynomial forms of a space. For <simply connected> finite-type spaces, $V^i$ is dual to $\pi_i(X)\otimes\mathbb Q$. A proposed finite model must have its <cohomology> and representing <quasi-isomorphism> checked; matching a list of relations alone is insufficient.
