## Why They Matter
Matias Frosterus represents a crucial bridge between traditional library science and modern semantic web technologies. His work has transformed how libraries approach data infrastructure, moving from siloed catalog systems to interconnected, machine-readable knowledge bases. By championing linked open data principles in library contexts, Frosterus has enabled cultural heritage institutions to participate in the broader semantic web ecosystem, making their collections discoverable through new channels and applications. His leadership in BIBFRAME implementation and ontology development has set standards that other institutions follow, effectively future-proofing library data for an increasingly digital world. Without his contributions, libraries would struggle to maintain relevance in an era where data interoperability and machine learning applications are becoming essential for information discovery.
