"In library and archival science, digital preservation is a formal endeavor to ensure that digital information of continuing value remains accessible and usable."
The preservation of museum collections through digital technology including strategies for digitization, metadata creation, and long-term storage.
Digital Object Management: How to manage digital objects, their metadata, preservation risks, and format migrations.
Preservation Planning: How to plan for digital preservation, selecting suitable storage media, and preservation policies.
Digital Curation: How to curate digital collections, manage accession process, and organize digital material.
Preservation Metadata: How to create and manage metadata for digital objects and their preservation needs.
File Formats and Standards: Understanding file formats, standardization, and their implications for digital preservation.
Risk Management: How to identify and assess risks involved in digital preservation, and develop a mitigation plan.
Storage Solutions: How to store and maintain digital objects based on the storage infrastructure, and implement disaster recovery plans.
Digital Forensics: Understanding digital forensics, data recovery, and data extraction from digital devices.
Copyright and Intellectual Property: How to manage digital intellectual property, fair use, and creative commons.
Digital Preservation Policy: Developing digital preservation policy, creating a digital preservation strategy, and managing funding for digital preservation.
Access and Use: Provide digital access and usage to digital collections, how to protect personal data and privacy.
Collaboration and Partnership: Build collaborative networks, manage partnerships, and create workflows for digital preservation.
Training and Education: Provide training programs, education materials, and resources to educate staff and researchers about digital preservation.
Legal and Ethical Issues: Understanding legal and ethical considerations for digital preservation, privacy, and data protection.
Emulation: Creating a software environment that can mimic the hardware and software of an original computer system to reproduce digital objects.
Migration: The process of transferring digital information from outdated formats to new formats to ensure its continued accessibility.
Bit-level Preservation: Preservation of digital objects by preserving their individual bits, ensuring that the information is kept intact in its original form.
Refreshment: Regularly copying digital data from one storage location to another to prevent data loss due to storage media degradation.
Locking: Stopping the accidental or intentional deletion, modification, or movement of digital materials by assigning specific user access permissions.
Fixity Verification: Ensuring the integrity of digital materials over time by checking the original bitstream against later versions, digital fingerprints, and checksums.
Intellectual Property Rights Management: Implementation of IP rights management guidelines or licenses that ensure proper attribution, ownership, and use of digital objects.
Metadata Quality Control: Organizing digital materials, incorporating appropriate metadata and taxonomies, ensuring the accuracy of metadata, and maintaining its consistency over time.
Rights Chains Preservation: Creating clear documentation and systematic records of the chain of rights owners to ensure that permissions and licenses are maintained over time.
Contextual Preservation: Preserving related software, hardware, and environmental settings that were used to create digital artifacts to ensure their long-term understandability and interpretability.
Geographic Preservation: Preserving the geographical location and cultural context of digital artifacts and their significance in their place of origin.
"It involves planning, resource allocation, and the application of preservation methods and technologies."
"It combines policies, strategies, and actions to ensure access to reformatted and 'born-digital' content."
"The goal of digital preservation is the accurate rendering of authenticated content over time."
"The Association for Library Collections and Technical Services Preservation and Reformatting Section of the American Library Association defined digital preservation as a combination of 'policies, strategies, and actions that ensure access to digital content over time.'"
"The need for digital preservation mainly arises because of the relatively short lifespan of digital media."
"Widely used hard drives can become unusable in a few years due to reasons such as damaged spindle motors, and flash memory can start to lose data around a year after its last use."
"Currently, 5D optical data storage has the potential to store digital data for thousands of years."
"Archival disc-based media is designed to last for 50 years."
"It is sold by just two Japanese companies, Sony and Panasonic."
"M-DISC is a DVD-based format that claims to retain data for 1,000 years."
"Writing to it requires special optical disc drives."
"Reading the data it contains requires increasingly uncommon optical disc drives."
"Data stored on LTO tapes require periodic migration, as older tapes cannot be read by newer LTO tape drives."
"RAID arrays could be used to protect against the failure of single hard drives."
"Care needs to be taken to not mix the drives of one array with those of another."
"Widely used hard drives can become unusable in a few years."
"Flash memory can start to lose data around a year after its last use."
"5D optical data storage has the potential to store digital data for thousands of years."
