CHAPTER 5

Multi-Formatted and Embedded Documents

One of XML’s strengths is its ability to represent hierarchical data struc-
tures and relationships. An XML record could be generated that contains
information on a single document that is available in multiple physical
formats—with the unique features of each item captured within the XML
data structure. Or, in the case of EAD (Encoded Archival Description),
XML has the ability to capture structured relationships between items and
the collections in which they are a part.
