  In recent times online educational applications more and more are requested
to provide self-consistent learning offers for students at the university
level. Consequently they need to cope with the wide range of complexity and
interrelations university course teaching brings along. An urgent need to
overcome simplistically linked HTMLc ontent pages becomes apparent. In the
present paper we discuss a schematic concept of educational content
construction from information cells and introduce its implementation on the
storage and runtime layer. Starting from cells content is annotated according
to didactic needs, structured for dynamic arrangement, dynamically decorated
with hyperlinks and, as all works are based on XML, open to any presentation
layer. Data can be variably accessed through URIs built on semantic path-names
and edited via an adaptive authoring toolbox. Our content management approach
is based on the more general Multimedia Information Repository MIR. and allows
for personalisation, as well. MIR is an open system supporting the standards
XML, Corba and JNDI.
