Trustworthy preservation and access metadata using distributed ledger technology (DLT)

Description

Trusted digital repositories require maintaining the integrity and authenticity of digital objects throughout their lifecycle. Digital signatures can establish trust regarding events such as submission, dissemination, and archiving. The PREMIS metadata standard is commonly used for recording preservation information, and agents performing events related to digital objects. Our approach utilizes distributed ledger technology (DLT) to record PREMIS entities in a trustworthy manner, following European eArchiving Initiative standards. This enhances trust in electronic archiving by providing auditable preservation and access metadata. PREMIS metadata can also define rights and certificates for OAIS functions, and integration with identity services enables access authorization. A software ontology or taxonomy is needed for compliance with GDPR, and DLT can provide GDPR-compliant access to repository data, crucial for scientific purposes such as data science and big data.
