This paper describes the aDORe repository architecture designed and implemented for ingesting, storing, and accessing a vast collection of Digital Objects at the Research Library of the Los Alamos National Laboratory. The aDORe architecture is highly modular and standards-based. In the architecture, the MPEG-21 Digital Item Declaration Language is used as the XML-based format to represent Digit...

This paper describes relationships between the Open Archival Information System Reference Model (OAIS RM) and the archival practices of the NOAA National Oceanographic Data Center (NODC). The OAIS RM defines a thorough approach to defining the processes, entities, and framework for maintaining digital information in an electronic archival environment without defining how to implement the framew...

This paper addresses the question: What would distributed digital preservation look like using the OAIS Reference Model? The challenge is the need for several organizations to cooperate to achieve distributed digital preservation; using replication, independence, and coordination to address the known threats to digital content through time. The main purpose of the paper is to present an Outer O...

The aim of the paper is to illustrate how the distributed aspects of digital preservation can be aligned in practice, with the concepts and principles of the Open Archival Information System (OAIS) Reference Model. There has been a growing awareness within the digital preservation community of the need for cooperation between organizations to address digital preservation requirements. One commo...

Excitatory synaptic activity in horizontal stratum oriens-alveus interneurons (OAIs) is driven by the recurrent collaterals of CA1 pyramidal cells and is strongly influenced by protocols that elicit synaptic plasticity in these principal neurons. Induction of LTD in the Schaffer collateral-CA1 pyramidal neuron synapse causes a passive down-regulation of stratum radiatum-evoked excitatory synapt...

This poster proposes mapping properties identified by both creators of video games as significant into the OAIS reference model. This research uses the framework provided by Giaretta et al. (2009), outlined as a clarification about the relationship between OAIS and significant properties, as a starting point. Utilizing data from the Preserving Virtual Worlds II grant and data from interviews wi...

Since its initial publication over a decade ago, the OAIS Reference Model, its concepts and terminology, have become essential to the digital preservation discourse. In this discourse, the topos – or myth – of “OAIS compliance” continues to play a central role as archives and repositories seek to demonstrate their fitness for the challenge of digital preservation. After briefly considering what...

Design/methodology/approach: We conducted two focus group sessions and one individual interview with eight employees at the world’s largest social science data repository, the Interuniversity Consortium for Political and Social Research (ICPSR). By examining their current actions (activities regarding their work responsibilities) and IT practices, we studied the barriers and challenges of archi...

This paper describes work being done towards a Framework for Applying the Reference Model for an Open Archival Information System (OAIS) to Distributed Digital Preservation (DDP). Such a Framework will be helpful for future analyses and/or audits of repositories that are performing digital preservation in highly distributed ways. A great deal of work has already been accomplished toward the Fra...
