DSpace How-To Guide: Tips and tricks for managing common DSpace chores

PDF fileThis short booklet is intended to introduce the commonest non-obvious customization related tasks for newcomers to DSpace administration. It has been written against the current stable version 1.3.2 of DSpace. We have tried to include instructions for different operating systems as required; most customizations, however, work identically cross-platform

Improving DSpace Backups, Restores, Migrations

In the past, backing up your DSpace contents has involved semi-synchronized backups of both your database and your files. Although this procedure generally works fine, it can prove problematic when you suddenly need to restore the contents of a single Community, Collection or Item (both metadata and files). There is also the problem of metadata and content files residing in separate backups - if either one of these backups becomes corrupted, it is nearly impossible to completely restore your DSpace contents. This talk will introduce a new DSpace feature being developed as part of the DuraCloud integration project. This new feature will allow you to export your entire DSpace Community / Collection hierarchy (including all Items, and their metadata and files) into a series of METS-based packages. These METS-based packages may be used to restore all of your DSpace contents (into another DSpace), or just the contents of a single Community, Collection or Item. These packages can also provide a more stable way to backup your DSpace contents, or an additional means of getting content in or out of DSpace. This work is based on a DSpace plugin built as part of the MIT PLEDGE project; however it has been updated to allow for a complete restore of your DSpace hierarchy

On the importance of including vegetation dynamics in Budyko's hydrological model

The Budyko curve describes the patterns observed between between climate, evapotranspiration and run-off and has proven to be a useful model for predicting catchment energy and water balances. In this paper we review the Budyko curve's underlying framework and, based on the literature, present an argument for why it is important to include vegetation dynamics into the framework for some purposes. The Budyko framework assumes catchments are at steady-state and are driven by the macro-climate, two conditions dependent on the scales of application, such that the framework's reliability is greatest when applied using long-term averages (≫1 year) and to large catchments (> 10 000 km2). At these scales previous experience has shown that the hydrological role of vegetation does not need to be explicitly considered within the framework. By demonstrating how dynamics in the leaf area, photosynthetic capacity and rooting depth of vegetation affect not only annual and seasonal vegetation water use, but also steady-state conditions, we argue that it is necessary to explicitly include vegetation dynamics into the Budyko framework before it is applied at small scales. Such adaptations would extend the framework not only to applications at small timescales and/or small catchments but to operational activities relating to vegetation and water management

Impact of CO2 fertilization on maximum foliage cover across the globe's warm, arid environments

Satellite observations reveal a greening of the globe over recent decades. The role in this greening of the "CO2 fertilization" effect-the enhancement of photosynthesis due to rising CO2 levels-is yet to be established. The direct CO2 effect on vegetatio
