DiGS is a distributed-data management system that combines commodity storage resources — such as file servers and SRM servers — into a large-scale, unified file repository, which is presented to the end-user through an easy-to-use, lightweight client toolkit.

DiGS is built on top of the Globus Toolkit and the EGEE application stack.

The key features of DiGS are:

capacity for multi-Terabyte, distributed storage.
robustness with automatic and transparent replication of data across multiple sites.
continuous data validation and consistency checking.
support for bulk data-transport operations.
security based on standards-compliant techniques for authentication and authorisation.
capability for data provenance with application-specific metadata.
simple and intuitive client tools.

XMLDiff is tool for automatically comparing the content of XML files. For more information view the documentation or contact the development team. We would be interested to hear if you use XMLDiff. Send an e-mail to George Beckett describing your usage.

DiGS 3.1 is released

Posted on 2010-11-17 by Mark Beckett

The team is pleased to announce the release of DiGS Version 3.1. The main change, in this version, is the inclusion of support for SRM-based storage technologies (such as DPM and StoRM). Full details of how to add SRM storage to a data grid is provided in the DiGS 3.1 Setup Guide. Second, the technology preview of the new Java-based GUI client has matured, and should be sufficiently stable for general use. The GUI client can be run on Unix/Linux, Microsoft Windows, and Mac OS platforms,... (see more)
