The Linked Open Data Cloud

What it is The Linked Open Data Cloud site hosts a diagram of datasets published in Linked Data format, organized into domain subclouds. It provides historical diagram releases, raw data, and the LOD Cloud Draw generator.

Key concepts Resolvable HTTP(S) URIs; RDF representations; cross-dataset RDF links; RDF crawling, dumps, or SPARQL access; domain subclouds; reusable diagram data.

How you’d use it Browse the diagram to see connected Linked Data datasets, download a historical PNG, SVG, or JSON release, or submit a qualifying dataset after publishing it according to the site’s Linked Data criteria.

LLM angle none stated

Pitfalls & lessons Inclusion requires at least 1,000 triples, at least 50 links to an existing diagram dataset, RDF resolution, and access to the entire dataset. The site calls the 50-link threshold arbitrary and says the submission process is still under development.

Verdict A useful visual and machine-readable map of the Linked Data ecosystem, with explicit—but partly pragmatic—admission rules.
