Changed #

• Triple, IriTerm, BlankNodeTerm and LiteralTerm classes now output in n-triple style in .toString() for better readability of debug output.
• Included information about json-ld in README and homepage.

Added #

• Added support for N-Triples format, including parser and serializer implementations
  • Implemented N-Triples as per W3C RDF 1.1 N-Triples specification
  • Added proper escaping and validation for N-Triples syntax
  • Integrated N-Triples format into the standard formats registry
  • Available via MIME type 'application/n-triples' and file extension '.nt'

Added #

• Added new factory methods LiteralTerm.integer(), LiteralTerm.decimal(), and LiteralTerm.boolean() for more concise and type-safe creation of common literal types.
• Updated TurtleParser to use these specialized factory methods for literal values.
• Enhanced TurtleSerializer to use native syntax for integer, decimal and boolean literals, resulting in more idiomatic and concise Turtle output.
• Enhanced TurtleSerializer to use native syntax for lists (aka rdf collections: ex:Person1 ex:someProperty ("foo" "bar" "blub");) and sets (aka multiple triple per subject/predicate pair: ex:Person1 ex:someProperty "foo", "bar", "blub";).

Fixed #

• Export exceptions

Fixed #

• More dependency cleanups

Fixed #

• unused http dependency was removed

Fixed #

• Fixed tests to use relative paths instead of absolute paths for better portability
• Improved examples for handling broken Turtle syntax

Added #

• Enhanced Turtle parsing flexibility with configurable parsing flags in TurtleTokenizer

Fixed #

• Made Turtle parser more robust when processing real-world datasets with syntax variations
• Enhanced error messages to be more informative for debugging parsing issues

Fixed #

• Important fix: build.yaml should not have been committed, it breaks the build of user projects

Changed #

• Removed a deprecated annotation that was no longer needed after the vocabulary cleanup

Removed #

• BREAKING CHANGE: Removed all deprecated vocabulary classes from the vocab directory
  • Removed all previously deprecated vocabulary classes (SchemaProperties, SchemaTypes, SchemaPersonProperties, etc.)
  • Users should now use direct IriTerm instances instead of vocabulary classes
  • Example: replace SchemaProperties.name with IriTerm('https://schema.org/name')
• Updated examples to use direct IriTerm instances rather than vocabulary constants

Added #

• Improved documentation around IriTerm usage patterns
• Added more comprehensive test coverage for core RDF functionality

• BREAKING CHANGE: Marked all vocabulary classes as deprecated
  • Added @deprecated annotation to all classes in vocabulary modules (acl, dc, dc_terms, foaf, ldp, etc.)
  • Classes will be removed in a future release due to API design concerns
  • Users should migrate to the upcoming new vocabulary API
• Improved code documentation
• Enhanced developer warnings for approaching breaking changes

• Minor formatting and style improvements in core files.
• No breaking changes; all public APIs remain backward compatible.

• Example and documentation now consistently use canonical RDF vocabularies (e.g., http://xmlns.com/foaf/0.1/) with http://, not https://.
