Modifying links leads to complications if the data is restored from an archive, so we will not require any such change. Instead, add a non-normative note: Since providers may support deletion of baselines, clients must not assume that references to baselines can be resolved; like any other resource, clients must be prepared to handle 404 errors. Since baselines are normally linked into a provenance chain using the oslc_config:previousBaseline property, servers may elect to leave a stub resource (one with a minimal set of properties) behind instead of truly deleting a baseline. Servers SHOULD add the property oslc:archived=TRUE on a reduced form of a partially deleted baseline.
