This document discusses semantic web, triples, and cultural heritage. It provides examples of triples about historical figures like Floris V that connect subjects to objects via predicates. It also discusses challenges of creating triples like missing authority files, issues with context and mappings, and establishing authority. Visualization of triples is mentioned as a way to make the data visible and manageable.

“Metadata, like the electrical grid and the
highway system, fades into the background of
everyday life, taken for granted as just part of what
makes modern life run smoothly.”
“Metadata”, Jeffrey Pomeranz, Cambridge MA. 2015

“What differentiates semantic metadata from
metadata is the level of interconnectedness.
Semantic metadata is deeply interlinked and richly
contextualized.”
