What is a graph triple?

What is a graph triple?

At the core of RDF is this notion of a triple, which is a statement composed of three elements that represent two vertices connected by an edge. It’s called subject-predicate-object. Subject will be a resource, or a node in the graph.

What is an Rdfs label?

rdfs:label is an instance of rdf:Property that may be used to provide a human-readable version of a resource’s name.

What are RDF graphs?

The Resource Description Framework, more commonly known as RDF, is a graph data model that formally describes the semantics, or meaning of information. It also represents metadata, that is, data about data. RDF consists of triples.

What is the meaning of Rdfs?

Resource Description Framework Schema
RDF Schema (Resource Description Framework Schema, variously abbreviated as RDFS, RDF(S), RDF-S, or RDF/S) is a set of classes with certain properties using the RDF extensible knowledge representation data model, providing basic elements for the description of ontologies.

What is a Quadstore?

Quadstore is a LevelDB-backed RDF graph database for Node. js and the browser with native support for quads and querying across named graphs, RDF/JS interfaces and SPARQL queries.

What is a triple in data?

A triple is a data entity composed of subject-predicate-object, like “Bob is 35” or “Bob knows Fred”. Much like a relational database, information in a triplestore is stored and retrieved via a query language. Unlike a relational database, a triplestore is optimized for the storage and retrieval of triples.

Is Rdfs an ontology?

RDF Schema (RDFS) is a language for writing ontologies. An ontology is a model of (a relevant part of) the world, listing the types of object, the relationships that connect them, and constraints on the ways that objects and relationships can be combined.

What is the difference between RDF and Rdfs?

RDF and RDF are ontology based languages. RDF is the minimum ontological representation, expresing the relation among two indivuals vía a predicate. RDFS is an extension of RDF that enables subsumption relations.
