## Why It Matters
Medical Subject Headings RDF matters because it makes the National Library of Medicine’s controlled vocabulary, MeSH, available in RDF form through an official website maintained by the NLM. Providing MeSH in RDF allows the vocabulary to be represented as structured, machine-readable data aligned with RDF specifications. This enables users, institutions, and systems that work with RDF data to access MeSH terms and metadata directly from the NLM’s authoritative source. The combination of an official publisher (United States National Library of Medicine), a fixed web location (https://id.nlm.nih.gov/mesh/), and an RDF encoding positions the resource as a consistent point of access for MeSH in semantic-web and linked-data contexts. The site’s publication location is Bethesda, and the resource is delivered in English.
