Welcome to iSpheres

ISpheres provide a distributed interoperable solution to serving a range of data - from images, sound, video and text to databases and GIS datasets. Each ISphere can manage several heterogeneous collections of digital objects, translate metadata specific to each collection into a common interoperable format, and serve digital objects transformed as required by the requesting application.

ISpheres include their own web services, so they can be installed on any Internet-connected computer with the Java runtime, making their digital object collections discoverable, searchable, transformable and downloadable. Individual ISpheres are registered with a global directory at www.ispheres.org, making them and their collections discoverable.

Any ISphere can search and retrieve data from any other ISphere (subject to authorisation) and present the results in an integrated list of resources, as well as serving data on-demand to client applications. Communication with an iSphere is through SOAP/XML.

ISpheres provide a new way of making information available to the outside world as DATA rather than web pages, with minimal effort. The concept and initial design were developed by Ian Johnson at the Archaeological Computing Laboratory (ACL), University of Sydney with input from Daniel Burn and Chris Albone from the Faculty of Medicine and supported by funding from the Australian Partnership for Sustainable Repositories(APSR).
