What is RDF Store
An RDF store, or triplestore, is a type of NoSQL graph database designed for storing and querying Resource Description Framework (RDF) data. RDF represents knowledge as subject-predicate-object triples that form graph structures.
RDF stores provide native support for Semantic Web standards like RDF, RDFS, OWL, SPARQL to manage data based on meaning and relationships between entities. Examples include Ontotext GraphDB, Stardog, and AWS Neptune. RDF stores are often used together with graph databases and document stores.
What does it do/how does it work?
An RDF store ingests data modeled as RDF triples representing facts as graph structures. Sophisticated indexing and query optimization enables fast traversals and lookups of entities based on meanings and relationships encoded in RDF graphs.
RDF stores utilize standards like RDF and SPARQL to model, store, query and manage both schema information and instance data within one graph-oriented database. APIs allow loading, storing and querying RDF triples.
Why is it important? Where is it used?
RDF stores allow building intelligent knowledge-oriented applications using semantic data modeling. Use cases include knowledge graphs, semantic search, connected data repositories, inferencing and reasoning engines.
Domains like scientific knowledge management, metadata management, linked open data initiatives, and artificial intelligence leverage RDF stores to handle complex web-scale graph data based on real-world entities and relationships.
