Beispiel

In this contrived example, a canonical reference to the same organisation is provided in four different ways.

<author n="1">
 <name ref="http://nzetc.victoria.ac.nz/tm/scholarly/name-427308.html"
  type="organisation">New Zealand Parliament, Legislative Council</name>
</author>
 
<author n="2">
 <name ref="nzvn:427308"
  type="organisation">New Zealand Parliament, Legislative Council</name>
</author>
 
<author n="3">
 <name ref="./named_entities.xml#o427308"
  type="organisation">New Zealand Parliament, Legislative Council</name>
</author>

The first presumes the availability of an internet connection and a processor that can resolve a URI (most can). The second requires, in addition, a prefixDef that declares how the nzvm prefix should be interpreted. The third does not require an internet connection, but does require that a file named named_entities.xml be in the same directory as the TEI document. The fourth requires that an entire external system for key resolution be available.
