The practice of exposing bibliographic, authority, and related dataset content as RDF resources with dereferenceable URIs and inter‑resource links so that datasets can be semantically connected, queried, and reused across systems.

Principle

Modeling records as RDF with stable URIs and explicit links to external vocabularies permits machine‑readable entity reconciliation and federated discovery without prior centralized alignment of identifiers.

Demonstration

Illustrative scenario → A library converts its authority file to RDF, assigns HTTP URIs to agents, and uses rdf:seeAlso and owl:sameAs to link to external vocabularies. Recognition: other services dereference those URIs and discover matches. Action: external aggregators import links to enhance search and disambiguation. Consequence: improved interoperability and cross‑catalog discovery without duplicating core data.

Misapplication

Mistaken interpretation: publishing an RDF dump equals Linked Data. Error: publishing triples without stable, resolvable URIs or without meaningful links to other resources fails to enable the web‑scale linking and discovery that Linked Data requires.

Consequence

Linked Data publishing enhances discoverability, reusability, and machine interoperability of bibliographic and authority data; it requires investment in identifier strategies, ontology selection, link maintenance, and governance of vocabularies and provenance.

Reversal

Where controlled vocabularies or external link targets do not exist or the audience lacks RDF consumption capabilities, simpler REST APIs or well‑structured JSON‑LD dumps may be more pragmatic initial steps than full Linked Data deployment.

Boundary

Clearly within: bibliographic records, authority files, subject headings and their mappings expressed as RDF with resolvable URIs and links. Boundary case: metadata exposed as RDF for internal use only without dereferenceable URIs. Clearly outside: opaque data dumps lacking identifiers or any interlinking semantics.

Semantic Tension

Interoperability ↔ Control — publishing linked identifiers increases interoperation and reuse but reduces unilateral control over downstream uses and requires governance of shared vocabularies and identifiers.

Synthesis

Linked Data publishing is an infrastructure approach: it shifts work from exchanging document payloads to publishing persistent, linkable identifiers and semantics so that machines can discover, relate, and integrate bibliographic information at web scale.
