Turtle
Turtle (Terse RDF Triple Language) is a text-based syntax for serializing RDF (Resource Description Framework) data, designed to be human-readable and easy to write. It represents RDF triples (subject, predicate, object) in a compact format using prefixes, URIs, literals, and blank nodes, making it suitable for data interchange and configuration in semantic web applications. Turtle is a subset of the more complex SPARQL query language and is widely used in linked data and knowledge graph projects.
Developers should learn Turtle when working with semantic web technologies, linked data, or knowledge graphs, as it provides a straightforward way to encode RDF data for storage, sharing, and processing. It is particularly useful in scenarios involving data integration, ontology development, or when using tools like Apache Jena or RDFlib, where human-readable RDF serialization is preferred over formats like RDF/XML. Turtle's simplicity also makes it ideal for prototyping and debugging RDF-based applications.
