TurtleCodec class final

RDF Codec implementation for the Turtle serialization format.

Turtle (Terse RDF Triple Language) is a textual syntax for RDF that is both readable by humans and parsable by machines. It is a simplified, compatible subset of the Notation3 (N3) format.

Turtle Syntax Overview

Turtle has several key features that make it popular for RDF serialization:

Prefixed names: Allow abbreviation of IRIs using prefixes

@prefix foaf: <http://xmlns.com/foaf/0.1/> .
<http://example.org/john> foaf:name "John Smith" .

Lists: Compact representation of ordered collections

<http://example.org/list> <http://example.org/property> (1 2 3) .

Predicate lists: Group multiple predicates for the same subject

<http://example.org/john> foaf:name "John Smith" ;
                          foaf:age 25 ;
                          foaf:mbox <mailto:john@example.org> .

Object lists: Group multiple objects for the same subject-predicate pair
```
<http://example.org/john> foaf:nick "Johnny", "J", "JJ" .
```

Blank nodes: Represent anonymous resources

<http://example.org/john> foaf:knows [ foaf:name "Jane" ] .

File Extension and MIME Types

Turtle files typically use the .ttl file extension. The primary MIME type is text/turtle.

inherited
encode(RdfGraph input, {String? baseUri, RdfGraphEncoderOptions? options}) → String: Encodes an RDF graph to a string representation in this codec
inherited
fuse<R>(Codec<String, R> other) → Codec<RdfGraph, R>: Fuses this with other.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
inherited
