Open clusters are key tracers of Milky Way, as both chemical and age tracers. The use of open cluster to provide significant constraints on galaxy evolution, however, has been limited due to discrepancies in measuring abundances from different studies. This work seeks to add additional southern open clusters into the SDSS/APOGEE metallicity system. We analyze medium resolution spectra of giant stars in 31 open clusters have been obtained and analyzed using The Cannon to determine [Fe/H] metallicities accurate to 0.15 dex. This uniform analysis is compared for roughly half of the clusters with previous results, and we present metallicities for the first time for 12 open clusters.
