Linked Data
A Knowledge Graph that is available on the Web and interlinked with additional external Knowledge Graphs, also on the Web.
Ontology
A type of controlled vocabulary establishing a shared understanding of concepts, categories, and relationships within a subject area.
Resource Description Framework (RDF)
A standard model for representing and linking structured information on the web, used by the Virtual Treasury to store knowledge graph data.
Schema: the framework for recording and organizing an entity’s attributes and relations. Each entity type has its own schema.
Structured data: data which conforms to a data model and has a well defined structure.
Subgraph: a smaller grouping of information within the Knowledge Graph.
Triple: <Subject, Predicate, Object> – a statement used to construct the knowledge graph by defining attributes and relationships
- Subject – a thing, often an entity
- Predicate – defines the relationship between the subject and the object
- Object – the entity or attribute related to the subject
Vocabulary: a formal standard for the entity types and relations. It is usually seen as a lightweight version of an ontology.
