Modern measurement instrumentation
combined with multimedia databases and
the appropriate software tools can offer a
very rich and coherent description of a
cultural object a description that meets
not only the needs of a virtual museum,
but also the very demanding and detailed
requirements of an in-depth, precise and
accurate scientific study, even from remote
locations.
ACKNOWLEDGEMENTS
T
he 3D ArchGIS project at CETI is a
collaborative effort of specialists in
various fields of science and technology, as
is clearly shown through the professional
expertise of the members of the develop-
ing team: Dr C. Chamzas (Electrical and
Mechanical Engineer), Dr N.Tsirliganis
(Nuclear Physicist), Dr D.Tsiafakis
(Archaeologist), Dr Z. Loukou (Chemist),
G. Pavlidis (Electrical and Computer
Engineer), A.Tsompanopoulos (Electrical
and Computer Engineer), K. Stavroglou
(Electrical and Computer Engineer), D.
Papadopoulou (Chemist),V. Evagengelidis
(Archaeologist), A. Koutsoudis (Multimedia
Engineer), and F. Arnaoutoglou (Program-
mer).We believe this mixture of specialties
reflects the demands of archiving of Cultural
Objects in the twenty-first century.
Addressing bandwidth challenges will
require innovative methods of data com-
pression, including the 3D models, com-
bined with progressive loading and display.
At its current implementation the applica-
tion is focused on mapping physicochemi-
cal data on the surface of the 3D models;
future versions are designed to be more
flexible on the type of mapped data and
will allow mapping not only on the surface
of the model but on its entire volume as
well.
CONCLUSION

D-digital archiving and presentation
provides scientists and the general pub-
lic with powerful means for the registra-
tion, documentation, preservation, display
and dissemination of our cultural heritage.
Figure 10). 3D ArchCAD communicates
with the server by performing calls to
PHP (a server based script language) pages
and retrieving the output (simple text)
from the server as a data set of input
parameters.This technique is implemented
by making use of operating system specific
calls (which makes this part of the code
platform dependent).
FUTURE DEVELOPMENT
3
D ArchGIS is an experimental applica-
tion and still under development.
Currently, it is on the second beta imple-
mentation. Future implementations of 3D
ArchGIS will address operating system
dependency, which is one of the most seri-
ous limitations, and the needs of users with
low bandwidth Internet connections.

uke University is about to embark
on a major initiative to deploy an
open source Web content management sys-
tem (CMS) as an enterprise Web applica-
tion.Two years in the planning, the
university library has played a pivotal role
in defining the need, establishing the tech-
nological boundaries of the initiative, and
marshalling the resources for the library to
take advantage of Duke's overall invest-
ment in CMS software and services.This
brief article explores the particular oppor-
tunities and challenges that are represented
by the choice of Zope as the university's
content management framework tool and
of Zope Corporation as a provider of
development services.The conclusion of
this article is that
Web content man-
agement technolo-
gy, if the fit is right,
may be a particu-
larly useful lever of
innovation for
libraries in a feder-
ated institutional
environment.
