Sample interview questions: Describe your understanding of metadata aggregation and the role of metadata harvesting protocols.
Sample answer:
Metadata aggregation involves the systematic gathering and consolidation of metadata from multiple sources to create a comprehensive and integrated metadata collection. This process plays a crucial role in enhancing resource discovery, facilitating data integration, and supporting various library services.
Metadata harvesting protocols, such as OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting), are essential tools for metadata aggregation. These protocols enable automated data retrieval from distributed repositories by using standardized mechanisms for querying, retrieving, and transferring metadata. Metadata harvesters, which are software applications, utilize these protocols to efficiently collect metadata from various sources.
The aggregated metadata can be stored in a central repository or distributed across multiple systems. It is then organized and indexed to facilitate efficient searching and retrieval. Aggregated metadata can be used to create union catalogs, subject guides, research guides, and other tools that provide unified access to distributed resources.
Metadata aggregation offers several advantages. It increases the visibility and accessibility of resources by bringing together metadata from diverse sources into a single platform. This enables users to se… Read full answer
