\\ It is important to make a distinction between Item and Record. The protocol text states: "...An item is conceptually a container that stores or dynamically generates metadata about a single resource in *multiple* formats, each of which can be harvested as [<span style="color: #0000ff"><span style="text-decoration: underline; ">records</span></span>|Record] via the OAI-PMH \[...\]A record is metadata expressed in a *single* format. A record is returned in an XML-encoded byte stream in response to an OAI-PMH request for metadata from an item...\[bold added by MF\] \\ Within DARE, the XML-encoded stream is constructed according to the XML-Container specifications. These specifications are given below. \\ The unique identifier identifies an item within a repository. Do not confuse this identifier with the element dc:identifier in Dublin Core. The OAI identifier has a different function: it is used to extract metadata, whereas the DC identifier is used to extract the resource.

According to the proclamation in the same document (*http://www.w3.org/TR/REC-xml-names/#ns-using), the DARE agreement will be that it is also possible to declare prefixes and namespaces in the ancestors of the document.*
