The HyperImage Authoring System is a web-based system consisting of three main components – server, connector and database – on to which the graphic frontend (the HyperImage Editor) is built. Data is exchanged between the HyperImage Editor and the HyperImage Server using standardised methods via SOAP/HTTP.
The HyperImage Server:
The server is a web service provided via a GlassFish application
server. Its intelligent caching strategies support the database’s
network performance, providing the data by means of a robust and
flexible object model.
HyperImage Connector:
External image repositories can be integrated in the HyperImage
authoring system by means of connectors. At present, the project
draws on the exemplary integration of a Fedora 3 repository
(Flexible Extensible Digital Object and Repository Architecture,
www.fedora.info).
HyperImage Database:
The database is the open source PostgreSQL database system. Binary
and metadata are imported from source repositories in the HyperImage
database by means of a defined WSDL interface (HyperImage Connector)
with the help of an application server on which Glassfish is used.
All the data can be exported using a project-specific XML structure for further processing or publication (in the HyperImage Reader, for example). The Fedora repository used for HyperImage at the Humboldt University is capable of providing material protected by copyright while maintaining respective access rights. As part of the project, interfaces have been developed to other image databases, so that user rights can be collated to user groups.
The software developed as part of the HyperImage project at the
computer and media services of the Humboldt University is available
as open source (1.0, www.sun.com) for any interested parties. The
code and the detailed software design description are circulated
via the SourceForge community platform
