 While the concept of stewardship might solve certain problems concerning cultural property by uniting contestants over ownership around a common aim, it is also liable to inherit transposed versions of some of the same problems. For instance, advocates of stewardship must contend with what and whose values will guide stewardship efforts. What exactly should be stewarded, why, and for the sake of whom? If, for instance, scientific or world heritage values take the lead, stewardship models can invite the same kinds of objections as universalist notions of cultural property that leave inadequate room for the purportedly special relationship between particular cultural groups and objects, or crowd out alternative value systems or sources of knowledge (Wylie 2005). These concerns can perhaps be avoided through a non-monolithic understanding of stewardship that acknowledges rights and duties for multiple parties with respect to single objects (Carpenter, Katyal, &amp; Riley 2009), but they remain concerns that advocates of stewardship models will need to address if stewardship is to serve as a viable substitute for an ownership model of cultural property.
