Glossary

  • RDF (Resource Description Framework): A standard model for structuring and linking data on the web in a machine-readable format.

  • Triple: A fundamental data structure in RDF, consisting of a subject, predicate, and object to represent a statement.

  • Ontology: A structured framework that defines relationships between concepts in a domain, providing semantic meaning.

  • SPARQL: A query language for retrieving and manipulating data stored in RDF format.

  • URI (Uniform Resource Identifier): A unique identifier used to reference a resource in RDF and on the web.

  • IRI (Internationalized Resource Identifier): An extension of URI that supports Unicode characters, enabling globally unique identifiers in multiple languages.

  • Linked Data: A method of publishing structured data using RDF and URIs to enable data interconnection across different sources.

  • Turtle: A syntax for writing RDF data in a human-readable format.

  • JSON-LD: A lightweight format for representing Linked Data using JSON, making it easier to integrate with web technologies.

  • Vocabulary: A set of predefined terms and relationships used in RDF to maintain consistency and interoperability.

  • Graph Database: A database optimized for storing and querying relationships in graph structures, often used with RDF data.

  • Graph: A collection of RDF triples, often identified by a URI to form a named dataset.

  • Blank Node: An anonymous resource in RDF without a URI, used to represent entities that do not require a global identifier.

  • Literal: A concrete value in RDF (e.g. a string, number, or date) used as the object of a triple.

  • Namespace: A prefix associated with a base URI to shorten and disambiguate terms from a specific vocabulary.

  • Resource: Any entity described in RDF, identified by a URI, IRI, or blank node.

  • Serialization: A specific syntax used to encode RDF data for storage or exchange, such as Turtle, JSON-LD, or RDF/XML.
