RDFpredikaatit

RDFpredikaatit are the core components of Resource Description Framework (RDF) statements. An RDF statement, also known as a triple, consists of a subject, a predicate, and an object. The predicate acts as the link or property that connects the subject to the object. It describes the relationship between the subject and the object. For example, in the statement "Helsinki is the capital of Finland", "is the capital of" is the predicate.

Predicates in RDF are typically represented as Uniform Resource Identifiers (URIs). This allows for a globally unique and unambiguous identification of the relationship being described. Common vocabularies, such as Schema.org, FOAF (Friend of a Friend), and Dublin Core, provide a rich set of predefined predicates for describing various types of entities and their properties. However, custom predicates can also be defined for domain-specific needs.

The choice of predicate is crucial for defining the semantics of the data. It dictates how the information can be interpreted and queried. When building RDF datasets, it is important to select predicates that accurately and clearly represent the intended relationships. Predicates are fundamental to creating linked data, enabling machines to understand and process information by following the relationships established between different resources. They are the verbs of the RDF sentence, defining the action or characteristic.
