Purpose
The short lifespan of digital signatures presents a challenge to the long-term preservation of digitally signed records. It can undermine attempts to presume, verify or assess their ...authenticity. This paper aims to investigate the challenges of the expiration of digital signatures in the context of digital archiving.
Design/methodology/approach
The paper identifies requirements for the long-term preservation of digitally signed records and compares them with the existing approaches. The characteristics, operational procedures and requirements of the technologies used for digital signatures are combined with the archival requirements to design a new model.
Findings
The paper proposes a new model of a blockchain-based system, which can be combined with any digital archive to assist the process of long-term preservation of digitally signed records.
Practical implications
The proposed model offers a new alternative to the current practice in the long-term preservation of digitally signed records, such as periodic resigning procedures or periodic wrapping of digitally signed records with archival timestamps.
Originality/value
The proposed TrustChain 2.0 model is based on previous research conducted as part of the InterPARES Trust project. It builds on TrustChain 1.0 by including digital signature certificate chain validity information in a blockchain thus avoiding the issues concerning records confidentiality and privacy information disclosure. The paper contributes not only to the development of archival science but also shows archival institutions on how to approach long-term preservation of digitally signed records.
Purpose
This paper aims to automate pre-ingest workflow for preserving digital content, such as records, through middleware that integrates potentially many information systems with potentially ...several alternative digital preservation services.
Design/methodology/approach
This design research approach resulted in a design for model- and component-based software for such workflow. A proof-of-concept prototype was implemented and demonstrated in context of a European research project, ForgetIT.
Findings
The study identifies design issues of automated pre-ingest for digital preservation while using middleware as a design choice for this purpose. The resulting model and solution suggest functionalities and interaction patterns based on open interface protocols between the source systems of digital content, middleware and digital preservation services. The resulting workflow automates the tasks of fetching digital objects from the source system with metadata extraction, preservation preparation and transfer to a selected preservation service. The proof-of-concept verified that the suggested model for pre-ingest workflow and the suggested component architecture was technologically implementable. Future research and development needs to include new solutions to support context-aware preservation management with increased support for configuring submission agreements as a basis for dynamic automation of pre-ingest and more automated error handling.
Originality/value
The paper addresses design issues for middleware as a design choice to support automated pre-ingest in digital preservation. The suggested middleware architecture supports many-to-many relationships between the source information systems and digital preservation services through open interface protocols, thus enabling dynamic digital preservation solutions for records management.
The Sapienza Digital Library (SDL) was released in December 2013 as result of a research project undertaken by Sapienza University of Rome and the Cineca consortium, since 2011. The digital library ...has been collecting materials coming from different kind of organizations including departments, libraries, and archives, belonging or donated to Sapienza University. The main result of the project was the development of an information framework supporting multidisciplinary organizations in managing digital materials, maintaining scientific, organizational and operational responsibilities. The technical solution adopted has found a trade-off between the standardization of the digital processes and products, and the preservation of the scientific materials’ peculiarities. The automatic standard translation, and the enrichment of the digital resource's metadata have reached the main goal of providing digital resources with the essential information necessary to their management in different technological contexts. The reuse of the digital information and contents, in different application contexts, has converted the holistic vision of a digital library in the implementation of an information infrastructure, setting the foundation for the long-term access and usability of its digital assets.
•We discuss the need for preserving public relations records on social media.•We suggest steps for preserving and retrieving public relations records on social media.•Public relations should follow ...archive guidelines for digital preservation.•Institutions should prepare their own internal rules for managing digital records.
Rapid technological development has shifted our society into a digital age, where social media tools are indispensable for our daily life. Public relations practitioners have recognized the power of these tools and have adopted them. Through social media they instantly post information to the public and the possibility of accessing to this information anytime they need and ability to prove authenticity of this information is very important for any of them. This paper discusses the value of information posted by public relations practitioners on social media and the need for the short and long-term preservation of such information. Based on our research, which was conducted across 24 national archives within the European Union, we collected important information on how to prepare organizations and their public relations practitioners for various issues surrounding the preservation of important information and allowing for its acquisition when necessary. The conclusion provides recommendations and guidelines for the preservation and acquisition of authentic public relations records transmitted to the public via social media.
The saturation of information services creates huge size of data every day. The growth of data needs expansion of storage systems, which keeps increasing the electric power for their operations and ...cooling. On the other hand, the saturation changes business work flows. Especially, the file-based information that has been preserved in videotape or chemical film needs consideration to long term digital preservation in addition to greenness. This report describes metrics in consideration of the storage power utilization and approaches to the long term digital preservation.
Long-term digital preservation is an important issue in data storage area. For years, magnetic media based solutions, such as tape and hard disk drive （HDD） based archive systems, monopolize the data ...archiving market due to their high capacity and low cost. However, in the era of big data, rapidly increasing volume, velocity, and variety of data set bring numerous challenges to the archive systems in various aspects, such as capacity, cost, performance, reliability, power consumption, and so on. In recent years, high capacity optical media, such as bluray discs （BDs） and holographic discs, emerge with the revival of optical storage. Due to the natural simple construction of the optical media, the archive systems based on those optical media, e.g., BD library, demonstrate attractive properties, such as cost per bit, reliability, power consumption, and so on, thus become feasible options in long-term digital preservation. In this paper, we reviewed and compared both the magnetic and optical media based solutions for long-term digital preservation, followed by a summarization on techniques to improve the optical media based archive system.
