For CAMS to work with PD CLS, item classes have to be setup that conform to CAMS PD output. The PD World file on your CAMS disks is setup to include the Item Classes needed for CAMS to work with PD CLS.
Classifications from CAMS can be exported using the Export Classifications Utility under the CAMS Utilities menu. Once you have set up your classifications in CAMS, export them using this utility, then import them into PD CLS using the import classifications option in the classifications window. For Demo Data purposes, the Classification World file is included on your CAMS disk which has classifications setup to be used with PD CLS.
