JISC Digital Media has surveyed a range of image management software developers to gather specific information about their systems. These are the responses from Greenstone.

Please note: The following information has been provided by the system developer/vendor in answer to a detailed survey carried out by JISC Digital Media, but has not been independently verified. It is provided to help you identify systems to evaluate in more detail, but you are advised to check with the system developer/vendor to see if the system has changed or there are later versions available.

There are a wide range of different image management systems available. To help identify those most suitable, we would recommend you also look at our introductory papers on Systems for Managing Digital Media Collections and Choosing a System for Managing your Image Collection.

To compare this system's features with those of others, please see the full list of systems who have responded to our survey on the Image Management Software page.

Greenstone www.greenstone.org
We asked the system developer to use 50-100 words to sum up and promote their system to a very broad audience: Greenstone is a suite of software for building and distributing digital library collections. It provides a new way of organizing information and publishing it on the Internet or on CD-ROM. It empowers users to build their own digital libraries, and is particularly aimed at universities, libraries, and other public service institutions. Greenstone is widely used internationally, and the 'Reader's Interface' has been translated into 50 language. The 'Librarian Interface' and documentation is available in about 6 languages. It runs on all versions of Windows, and Unix, and Mac OS-X. It is highly interoperable using contemporary standards.
