Rights Management and
Payment Technologies
131
To reduce the risks associated
with software development and
integration the Consortium agreed
to implement the DRM system on
a step-by-step basis, beginning with
a local rights management system
with only local contract capabilities
and no multilingual access.
Multilingual support was added.
Finally, distributed access and a dis-
tributed rights management system
with full multilingual thesaurus
support were added.The consortium
had to address a number of interface issues as they integrated their rights management
system with digital video archives.The base digital video archive relies on a CORBA
middleware framework within which the DRM system had to be embedded.

The
database storing the contracts had to be embedded in the overall storage and JDBC-
based interface architecture of the system,
220
and the user interfaces of the DRM system
also had to work with the existing Web-based search and retrieval interface.The user
interfaces of the overall system have been delivered as Web services.This development
strategy supported rapid programming and independent module testing.The deployment
of Web services has turned out to be an excellent choice for integrating the user inter-
faces and functionalities of the various partners: the technology has proved to be very
reliable.The structure of the project reflected its strong user orientation, and the broad-
casting and archive partners were heavily involved in defining the requirements of the
system, in providing the content, and in evaluating the systems. Future work on AMICI-
TIA will replace the multilingual thesaurus with a multilingual ontology dealing with the
rights negotiation and legal terms. At present the contracts describing rights have to be
encoded manually in XML. In future the ontology should help in editing contracts, or
better still it should interpret con-
tracts that are written in natural
(legal) language. If the application
were extended with billing and
accounting components it would
be possible to use it to enable
broader purchase of services and
content.
The DRM system was built to
support the exchange of content
between media professionals such as
journalists, editors, and footage cut-
ters.These people form a trusted
community where all transactions are covered by contracts.The peer-to-peer content
exchange network, protected by technical means such as passwords and virtual private

software, the integration of the DRM system caused no significant problems.
