 schemes provide unique identifiers for (possibly changing) virtual resources, but not all schemes provide curation opportunities. Curation of virtual resources has been defined as, “the active involvement of information professionals in the management, including the preservation, of digital data for future use.” [Yakel, E (2007)] For a persistent identification scheme to provide a curation opportunity for a virtual resource, it must allow real-time resolution of that resource and also allow real-time administration of the identifier.

-<p>URI persistence is a matter of policy and commitment on the part of the URI owner. The choice of a particular URI scheme provides no guarantee that those URIs will be persistent or that they will not be persistent.  HTTP [[RFC2616]] has been designed to help manage URI persistence. For example, HTTP redirection (using the 3xx response codes) permits servers to tell an agent that further action needs to be taken by the agent in order to fulfill the request (for example, a new URI is associated with the resource).

 <p>In addition, content negotiation also promotes consistency, as a site manager is not required to define new URIs when adding support for a new format specification. Protocols that do not support content negotiation (such as FTP) require a new identifier when a new data format is introduced. Improper use of content negotiation can lead to inconsistent representations.
