state would require a high-capacity data storage and,
more importantly, a dynamic data storage structure,
capable of growing according to the different
storage needs.
There is currently no explicit support for such a
scenario in the existing SCORM runtime, API or
data model. For example, although there are pro-
visions in the SCORM application profile that
can be used to load and store states such as
cmi.launch_data, cmi.suspend_data or cmi.core.lesson_
location, these data stores are severely limited in size
and cannot be accessed by other SCOs.
The addition of sequencing in SCORM 1.3,
however, provides an important building block for
constructing modular SCOs composed of re-usable
Cultural Learning Objects. In SCORM 1.3, the
logic for determining how to proceed through these
Shareable Content Objects (based on SCO status)
can now be written down as sequencing rules.
What is still missing is the ability to store com-
plex data from one SCO that can be retrieved by
another, so that the Shareable Content Objects can
be `knitted' into a complete and integrated learning
experience.This capability is crucial to the persis-
tence of the complex state information that is
generated by the most diverse Shareable Content
Objects and is currently stored and retrieved in
prop-rietary formats, and through proprietary
methods.The Shareable State Persistence Project
Team of IMS is working to propose extensions to
e-learning runtime systems (e.g. SCORM) that
enable the storage of - and shared access to - the
state information.This specification will enable e-
learning applications to be stopped and resumed
where the learner last left off. It is expected that
the work will be completed in November 2003,
but the standardisation process will require more
time.

ne of the projects included by Giunti Inter-

Framework
for developing an e-learning standards Application
Profile for Cultural Heritage is SCULPTEUR.
SCULPTEUR (Semantic and Content-based
Multimedia Exploitation for European Benefit) is a
three-year European project which started in May
2002. Its total investment amounts to Euro 3M and it
is co-funded by the European Commission within the
Fifth Framework's Information Society Technologies
(IST) Programme. SCULPTEUR involves ten
partners from three European countries in a multi-
disciplinary partnership with participants from
industrial, academic, research and cultural sectors.
