Sample interview questions: Describe your understanding of metadata preservation formats and the challenges associated with format obsolescence.
Sample answer:
Metadata preservation formats ensure the long-term accessibility and usability of metadata over time. By storing metadata in standardized and sustainable formats, institutions can mitigate the risk of data loss and ensure the ongoing value of their digital collections.
Various metadata preservation formats exist, including:
- Dublin Core (DC): A widely adopted metadata standard used for describing a wide range of digital resources.
- Metadata Encoding and Transmission Standard (METS): A standard specifically designed for preserving complex digital objects and their associated metadata.
- PREMIS (Preservation Metadata: Encoding and Representation Standard): A standard developed by the Library of Congress for preserving metadata about the provenance, condition, and authenticity of digital objects.
Each format offers advantages and use cases. For instance, DC provides a simple and interoperable way to describe basic resource metadata, while METS allows for the preservation of more complex metadata structures, such as those associated with multimedia objects. PREMIS, on the other hand, focuses on preserving detailed technical and administrative metadata essential for ensuring the authenticity and reliability of digital objects over time.
However, one of the significant challenges in metadata preservation is format obsolescence. As technology evolves, new metadata formats emerge, while older formats may become obsolete and unsupported. This can lead to difficulties in accessing and interpreting metadata created in older formats, potentially compromising the long-term preservation of digital collections.
To address format obsolescence, several strategies can be employed:
- Migration: Regularly migrating metadata from older formats to newer, more sustainable formats ensures its ongoing accessibility and usabil… Read full answer
