Overview

The University of Maryland is collaborating with SDSC/UCSD Libraries, and the National Center for Atmospheric Research (NCAR) to build the Chronopolis digital preservation environment based on the SRB and to ingest and preserve substantial collections from the two NDIIPP partners: California Digital Library (CDL) Web-at-Risk and the InterUniversity Consortium for Political and Social Research (ICPSR) DATA-PASS. The University of Maryland will use some of the software tools developed under the TPAP project, such as the SRB Replication Monitor, to support Chronopolis. In addition, the University of Maryland will expand and support its Chronopolis grid brick to provide up to 50TB of additional disk storage for this project, and will manage its node in the federated repositories in close coordination with SDSC and NCAR.
