testbed domains. In this case, our scenarios are related with the ingestion, retrieval
and preservation of IMPs.
The ICSRiM IMP Archival System has been designed and developed with the
CASPAR framework integrating a number of selected CASPAR components via
web services. The system has been used to implement and validate the preservation
scenarios.
The archival system is a web interface, shown in Fig. 22.13 , which communicates
with a Repository containing the IMPs and the necessary “metadata” for preserving
the IMPs. The first step for preserving an IMP is to create its description based on the
CIDOC-CRM and FRBRoo ontology. This information is generated in RDF/XML
format with the use of the CASPAR Cyclops tool. The Cyclops tool [ 241 ]isusedto
capture appropriate Representation Information to enhance virtualisation and future
re-use of the IMP. In particular, this web tool is integrated into the Archival System
and it used in order to model various IMPs.
During ingestion, the IMP files and the “metadata” are uploaded and stored in the
Repository with the use of the web-based IMP Archival System. For the retrieval
of an IMP, queries are performed on the “metadata” and the related objects are
returned to the user. The following Figure shows the web interface of the ICSRiM
IMP Archival system.
In case a change occurs in the dataset of an IMP, such as the release of a
new version of the software, the user has the ability to update the Representation
Information and the dataset of the IMP with the new modules (e.g. the version
of new software). A future user will be able to understand which one is the lat-
est version of a component and how these components can be reassembled for the
reproduction of the Performance by retrieving the Representation Information of
the IMP.
