Did you look at how status fetches and initialises the keyspace? Have a look at org.apache.cassandra.service.StorageService#effectiveOwnership. It uses a keyspace and its RF to measure ownership. The same method should work for any nodetool command that needs a keyspace. Note that depending on what you are using it for you may need to handle each strategy differently (and also handle LocalStrategy).
