Characteristics of metasources include the use of metadata schemas, support for cross-domain schema mappings, and the
Applications span several domains. In libraries and archives, metadata aggregators describe resources held by many institutions,
Benefits of metasources include improved discovery, enhanced metadata quality, and greater interoperability across systems. They also
Challenges involve maintaining metadata accuracy and timeliness, achieving semantic interoperability across domains, managing licensing and privacy
