Encoded Archival Description Tag Library, Version 2002
EAD Elements
<extptr> Extended Pointer
Description:
An empty linking element that uses attributes to connect the EAD document to an external electronic object, which is not part of the materials being described. Examples include graphic representations of a repository's seal or logo, and pointers to an institution's web page.
Use the ENTITYREF or HREF attribute to identify the external object.
Do not confuse with the Pointer <ptr> element, which is an internal link for movement from one place in a finding aid to another place in the same finding aid.
While XML Linking Language (XLink) Version 1.0, which is the basis for EAD linking elements, is a stable document, examples of EAD usage are hypothetical and have not been tested in real XLink-based applications. Those wishing to use XLink are encouraged to consult the specification available online at <http://www.w3.org/TR/xlink/>.
