In this chapter we argue that hyperdocuments administered by digi-
tal libraries have to be structured according to standardized storage and
exchange formats in order to allow for the manipulation functionality
required in digital library construction, maintenance and use. We demon-
strate how SGML and its extension, HyTime, can play this structuring
role, and how multimedia documents structured accordingly can be stored,
changed and maintained in the object-oriented database system VODAK.
Using the dynamic semantic extension facilities of VODAK it is illustrated
how the document structuring dynamics o ered by SGML and HyTime
can be accommodated in the database. In addition we discuss how this
facility can be combined with other system components to provide a rel-
evant portion of the functionality required for digital libraries.
