The Greenstone Digital Library Software

Digital libraries are large, organized, focused collections of information. The Greenstone software is intended to help people design and build such collections quickly and easily. Collections may be large—some comprise Gbytes of text; others include many millions of short documents. Additionally, far larger volumes of information may be associated with a collection—typically audio, image, and ...

Extending Greenstone for Institutional Repositories

We examine the problem of designing a generalized system for building institutional repositories. Widely used schemes such as DSpace are tailored to a particular set of requirements: fixed metadata set; standard view when searching and browsing; pre-determined sequence for depositing items; built-in workflow for vetting new items. In contrast, Fedora builds in flexibility: institutional reposit...

Greenstone: a platform for semantic digital libraries

This chapter illustrates the impact on a well–known digital library system – Greenstone – when it is moved from fixed modules and simple metadata–based structures, to open semantic digital library modules. This change has profound effects on the tools available to end–users to retrieve relevant content from the library, and an equally significant impact on the digital library (DL) architecture....

Paired metamorphic belts revisited

a r t i c l e i n f o Keywords: Eclogite HP granulite Paired metamorphic belts UHPM UHTM The modern plate tectonics regime is characterized by a duality of thermal environments, one representing the subduction zone and the other representing the arc–backarc or orogenic hinterland. This duality is the hallmark of one-sided (asymmetric) subduction, and the characteristic imprint of one-sided subd...
