Web Annotation: The Web’s Conversation Layer

on YouTube ↗39m

" summary

A concrete protocol and data model now exist: the W3C Web Annotation standard defines a model, a vocabulary and a protocol, serialized as JSON‑LD or embedded with RDFa, with selectors (textQuote, range, fragment) to pinpoint segments. An open source Hypothesis client highlights pages and posts annotations; scientists use group and tagging features to curate literature and projects like climatefeedback.org place scientist annotations on news articles. Adoption remains small, moderation and identity are unresolved, and portability and interoperability are the practical wins so far.
