  We define and study a family of link invariants $\mathit{HFK}_{n}(L)$.
Although these homology theories are defined using holomorphic disc counts,
they share many properties with $sl_{n}$ homology. Using these theories, we
give a framework that generalizes the conjectured spectral sequence from
Khovanov homology to $\delta$-graded knot Floer homology. In particular, we
conjecture that for all links $L$ in $S^3$ and all $n\ge 1$, there is a
spectral sequence from the $sl_{n}$ homology of $L$ to $\mathit{HFK}_{n}(L)$.
