TEI: Elements for pointers and links

• <ptr> (pointer) defines a pointer to another location.
  • Examples:
    • <p>This is discussed in <ptr target="#TEILite"/>.</p>
    • <p>This is discussed in <ptr target="​http://www.tei-c.org/TEI/Guidelines/SA.html"/></p>
    • <p>This is discussed in <ptr target="​http://mpdl.mpiwg-berlin.mpg.de/music/ramones/ramones_2004.xml#xpointer((id('page6'))/></p>
    • A pointer named "myId1" to "myId2" is here <ptr xml:id="myId1" target="#myId2"/>

• <ref> (reference) defines a reference to another location, possibly modified by additional text or comment.

• <link> defines an association or hypertextual link among elements or passages, of some type not more precisely specifiable by other elements (also possible between different documents)
  • Example: <note id="n3.284" type="imitation" place="foot" anchored="no"> <ref id="r3.284" rend="sc">...</ref> </note> <link targType="ref l" targOrder="Y" targets="r3.284 l3.284"/>

• <linkGrp> Link groups
  • Example: <linkGrp type="imitation" targType="note l" targOrder="Y"> <link targets="n2.79 l2.79"/> <link targets="n2.88 l2.88"/> <!-- ... --> <link targets="n3.284 l3.284"/> <!-- ... --> </linkGrp>

• <anchor> specifies a location or point within a document so that it may be pointed to.
• <seg> identifies a span or segment of text within a document so that it may be pointed to.
