Structured Data in 2021 and Beyond
summary
Overview of concrete tools and results: RDF/OWL and SKOS power taxonomy and ontology work, PoolParty is used to manage taxonomies and spin up graph DBs, and Wikidata provides Wikidata Q identifiers to disambiguate entities across 400+ languages. Federated SPARQL queries join Wikidata and OpenStreetMap live, enabling things like ATM location maps without custom code. Knowledge graphs index entities (not strings) to improve search. NASA DataKnots and the Space Apps hackathon supply reusable open datasets for real projects.
