Sorry about this, I steered you wrong.<div><br></div><div>The documentation is correct for the api call, you can only store metadata when updating an existing item.</div><div><br></div><div><br></div><div>You can only have one Metadata Value for an ItemRevision and for an (Element, Qualifier) pair. The metadata stored with the create.item call will use a blank string for the Qualifier, and so will the setmetadata call if you don't provide a Qualifier. So if you set x=y, then x=z, your metadata will be (X, '', Z). You could always add qualifiers via setmetadata and so have (X, Q1, Y) and (X, Q2, Z).</div>
