"In library and archival science, digital preservation is a formal endeavor to ensure that digital information of continuing value remains accessible and usable."
Ensuring that digital historical materials are properly maintained and accessible for future generations.
Digital Preservation: Digital preservation is the series of activities that are necessary to guarantee the survival of digital data over time.
Metadata: Metadata is the information that describes the content, context, and structure of digital objects.
File Formats: File formats are the specific way in which digital data is encoded and stored. Understanding file formats is crucial for understanding digital preservation.
Digital Stewardship: Digital stewardship is the overall management of digital objects and ensuring their long-term preservation and access.
Content Management Systems: Content management systems are programs that help to organize and manage digital content.
Storage: Storage is the process of managing and preserving digital data over time, including selecting the right storage media, and ensuring that the data is duplicated and backed up.
Risk Assessment: Risk assessment is the process of identifying and evaluating potential risks to digital data over time, and the measures that can be taken to mitigate those risks.
Preservation Metadata: Preservation metadata is the information that is necessary to ensure the long-term preservation of digital content.
Legal and Ethical Considerations: Legal and ethical considerations are important in digital preservation, particularly with regards to issues like copyright and intellectual property.
Digital Object Lifecycle: Understanding the digital object lifecycle is crucial for digital preservation, including the creation, storage, access, and disposal of digital objects.
Migration: It involves periodically transferring digital information to a new hardware or software environment to keep it accessible as technology progresses over time.
Emulation: It utilizes specialized software applications to mimic or emulate older computer platforms or software environments, to run older applications and preserve digital information.
Media Conversion: It involves the conversion of historical digital information into a new format, resulting in a new digital file that is more accessible than the original file.
Metadata Management: It involves adding descriptive information to digital materials that can be used to discover, understand, and use digital objects effectively.
Bit-Level Preservation: It is a technique that ensures that digital data and storage media remains intact and unchanged over long periods of time.
Content Integrity: It involves verifying that digital content has not been tampered with or altered in any way from its original format.
Digital Asset Management: It is a system of tools and processes that helps to organize, store, and manage digital assets for long-term preservation.
Authenticity Verification: It involves verifying that a digital object is a valid and reliable representation of the original object.
Digital Rights Management: It is a set of technologies and policies that enable digital objects to be accessed and used only by authorized users.
Trusted Digital Repositories: It involves the creation and management of a digital repository that adheres to established standards for preservation and access, ensuring the long-term preservation of digital objects.
Security measures: It includes encryption, access control, backup and recovery, intrusion detection and prevention, and other security measures to prevent unauthorized access, data breaches, or loss of information.
Web archiving: It is the preservation of digital information stored on the internet or the World Wide Web, which can be retrieved in the future for research or historical purposes.
Digital forensic: It involves retrieval, extraction, preservation, and analyzing digital data for legal or investigation purposes.
Preservation Metadata: It enhances the acquisition, management, preservation, and access of digital materials by providing necessary descriptive, technical, and administrative information.
Preservation format: It involves a standard format for storing and preserving digital information, which ensures long-term accessibility and sustainability.
"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."
