Colenda @ the University of Pennsylvania: Using a decoupled, pluggable architecture for object processing

This poster details the architecture of the repository and the deliverables of the first major release of Colenda, the open-source repository software developed at Penn Libraries.

Staff in Digital Library Development & Systems created Colenda, a long-term preservation ecosystem including Samvera, an open-source software framework for repository development, at its core. Colenda is a Samvera instance that provides materials-agnostic functionality for distributed workflows around administration of digital assets and metadata through a pluggable architecture for metadata schemata and entry. This poster offers a look at object processing workflows from the consumer end as well as a deep-dive into each component\u27s purpose in the software stack

Optimising metadata workflows in a distributed information environment

The different purposes present within a distributed information environment create the potential for repositories to enhance their metadata by capitalising on the diversity of metadata available for any given object. This paper presents three conceptual reference models required to achieve this optimisation of metadata workflow: the ecology of repositories, the object lifecycle model, and the metadata lifecycle model. It suggests a methodology for developing the metadata lifecycle model, and illustrates how it might be used to enhance metadata within a network of repositories and services

Designing an automated prototype tool for preservation quality metadata extraction for ingest into digital repository

We present a viable framework for the automated extraction of preservation quality metadata, which is adjusted to meet the needs of, ingest to digital repositories. It has three distinctive features: wide coverage, specialisation and emphasis on quality. Wide coverage is achieved through the use of a distributed system of tool repositories, which helps to implement it over a broad range of document object types. Specialisation is maintained through the selection of the most appropriate metadata extraction tool for each case based on the identification of the digital object genre. And quality is sustained by introducing control points at selected stages of the workflow of the system. The integration of these three features as components in the ingest of material into digital repositories is a defining step ahead in the current quest for improved management of digital resources

Planets: Integrated Services for Digital Preservation

The Planets Project is developing services and technology to address core challenges in digital preservation. This article introduces the motivation for this work, describes the extensible technical architecture and places the Planets approach into the context of the Open Archival Information System (OAIS) Reference Model. It also provides a scenario demonstrating Planets’ usefulness in solving real-life digital preservation problems and an overview of the project’s progress to date

Preparing to Preserve: Three Essential Steps to Building Experience with Long-Term Digital Preservation

Many organizations face complex questions of how to implement affordable and sustainable digital preservation practices. One strategic priority at the University Libraries at the University of Nevada-Las Vegas, United States, is increased focus toward preservation of unique digital assets, whether digitized from physical originals or born digital. A team comprised of experts from multiple functional library departments (including the special collections/archives area and the technology area) was established to help address this priority, and efforts are beginning to translate into operational practice. This work outlines a three-step approach: Partnership, Policy, Pilot taken by one academic research library to strategically build experience utilizing a collaborative team approach. Our experience included the formation of a team, education of all members, and a foundational attitude that decisions would be undertaken as partners rather than competing departments or units. The team’s work included the development of an initial digital preservation policy, helping to distill the organizational priority and values associated with digital preservation. Several pilot projects were initiated and completed, which provided realistic, first-person experience with digital preservation activities, surfaced questions, and set the stage for developing and refining sustainable workflows. This work will highlight key activities in our journey to date, with the hope that experience gained through this effort could be applicable, in whole or part, to other organizations regardless of their size or capacity

Digital curation and the cloud

Digital curation involves a wide range of activities, many of which could benefit from cloud deployment to a greater or lesser extent. These range from infrequent, resource-intensive tasks which benefit from the ability to rapidly provision resources to day-to-day collaborative activities which can be facilitated by networked cloud services. Associated benefits are offset by risks such as loss of data or service level, legal and governance incompatibilities and transfer bottlenecks. There is considerable variability across both risks and benefits according to the service and deployment models being adopted and the context in which activities are performed. Some risks, such as legal liabilities, are mitigated by the use of alternative, e.g., private cloud models, but this is typically at the expense of benefits such as resource elasticity and economies of scale. Infrastructure as a Service model may provide a basis on which more specialised software services may be provided. There is considerable work to be done in helping institutions understand the cloud and its associated costs, risks and benefits, and how these compare to their current working methods, in order that the most beneficial uses of cloud technologies may be identified. Specific proposals, echoing recent work coordinated by EPSRC and JISC are the development of advisory, costing and brokering services to facilitate appropriate cloud deployments, the exploration of opportunities for certifying or accrediting cloud preservation providers, and the targeted publicity of outputs from pilot studies to the full range of stakeholders within the curation lifecycle, including data creators and owners, repositories, institutional IT support professionals and senior manager

Digital Preservation Services : State of the Art Analysis

Research report funded by the DC-NET project.An overview of the state of the art in service provision for digital preservation and curation. Its focus is on the areas where bridging the gaps is needed between e-Infrastructures and efficient and forward-looking digital preservation services. Based on a desktop study and a rapid analysis of some 190 currently available tools and services for digital preservation, the deliverable provides a high-level view on the range of instruments currently on offer to support various functions within a preservation system.European Commission, FP7peer-reviewe
