  F. Jaeger presented the two-variable Kauffman polynomial of an unoriented
link L as a weighted sum of HOMFLY-PT polynomials of oriented links associated
with L. Murakami, Ohtsuki and Yamada (MOY) used planar graphs and a recursive
evaluation of these graphs to construct a state model for the sl(n)-link
invariant (a one-variable specialization of the HOMFLY-PT polynomial). We apply
the MOY framework to Jaeger's work, and construct a state summation model for
the SO(2n) Kauffman polynomial.
