The three Entities

Digital Library– An organization, which might be virtual, that comprehensively collects,

manages, and preserves for the long term rich digital content, and offers to its user communities specialized functionality on that content, of measurable quality and according to codified policies

Digital Library Systemg y y– A software system that is based on a defined (possibly distributed)

architecture and provides all functionality required by a particular Digital Library. Users interact with a Digital Library through the g y g y gcorresponding Digital Library System

Digital Library Management System– A generic software system that provides the appropriate software– A generic software system that provides the appropriate software

infrastructure both (i) to produce and administer a Digital Library System incorporating the suite of functionality considered foundational for Digital Libraries and (ii) to integrate additional software offering more refinedLibraries and (ii) to integrate additional software offering more refined, specialized, or advanced functionality

Different types of DLMSyp

Extensible Digital Library System – A complete Digital Library System that is fully operational with respect to basic/

foundational functionality required. It is based on an open software architecture, so that further software components can be incorporated on top of the ones already there with ease (DelosDLMS, Greenstone)with ease (DelosDLMS, Greenstone)

Digital Library System Warehouse – A collection of software components that encapsulate the core suite of DL functionality

and a set of tools that can be used to combine these components in a variety of ways (in Lego-like fashion) to create Digital Library Systems offering a tailored integration of functionalities. New software components can easily be incorporated into the Warehouse for subsequent combination with those already there (BRICKS, DILIGENT)DILIGENT)

Digital Library System Generator– A highly parameterized software system that encapsulates templates covering a broad

range of functionalities, including a defined core suite of DL functionality as well as any advanced functionality that has been deemed appropriate to meet the needs of the specific application domain Through an initialization session, the appropriate parameters are set and configured; at the end of that session, an application is automatically generated, and this constitutes the Digital Library System ready for y g , g y y yinstallation and deployment (MARIAN)

Supported Platforms

Operating system: Operating system:– Windows (any version)– Linux (any version)– Unix (most versions, e.g. Solaris) – Mac OS X

Restrictions:– No longer runs under Windows 3.1/3.11– For Librarian interface (GLI), need Java—

which is no longer supported on Windows 95

Documentation

The Greenstone system can be downloaded from the web site (www.greenstone.org)– available for Windows, Mac and Linux– recommended version for Windows is 2 85recommended version for Windows is 2.85– recommended version for Mac and Linux is 2.83

All (most) Greenstone documentation also available at the web site Best way to learn Digital Libraries and Greenstone is:

– Read the book from Ian Witten “How to build a Digital Library”, Morgan Kaufmann, 2010, ISBN 978-0-12-374857-7 (Second edition), , ( )

– execute the recommended exercises (see the 4-days workshop on the download page)

– study the demo collections (see Documented examples on the download– study the demo collections (see Documented examples on the download page)
