4 CUSTOMIZED ELEARNING –
DISCUSSION AND FUTURE
RESEARCH
The previous two sections represent our basic
approach to customized eLearning. User profiles
containing information about learners (e.g. display
device, learning preferences, level of proficiency,
etc.) are stored in a database as an XML document.
Information about learning materials is also as a set
of XML documents. This information about the
learning materials is actually metadata, or semantic
information about the materials (Al-Khalifa, 2006).
A set of data transformers (XSLT stylesheets) use
the user profiles and metadata to transform the
learning materials into a customized presentation in
an XML-based language such as SMIL 2.0. The
metadata which we have incorporated into our
prototype systems is limited, however we are
working to incorporate more advanced metadata, as
represented by IEEE-LOM (IEEE, 2002). A general
learning model (Gaeta, 2009) will be incorporated to
allow for modification of user profiles
