Release 3.3.1

When Mutable#load is called with a base_uri option, it takes precedence over the resource location.

Release 3.3.0

• Add support for directional language-tagged strings from RDF 1.2.
• Consolidate N-Triples and N-Triples Star grammars. Use LANG_DIR terminal instead of LANGTAG.
• Removes support for legacy text/plain (as an alias for application/n-triples) and text/x-nquads (as an alias for application/n-quads)
• Cleanup RDF* nomenclature, and use :quoted_triples instead of :rdfstar for supports?.
• Add :base_direction as something supported (or not) by writeable.
• Require rdfstar option to read directional language-tagged strings.
• Add missing Statement#dup. Does not duplicate blank node components.
• Added documentation to clarify that term canonicalization is not the same as Graph/Dataset canonicalization, which is impleented in the rdf-normalize gem.
• Add Enumerable#canonicalize method, which can be overridden by rdf-normalize, which normalizes each statement in an enumerable.
• Minimum Ruby version now 3.0.

Release 3.2.11

• Ruby extensions no longer necessary.
• Make Ruby warnings visible and reduce warnings.
• Updates to URI normalization. Fixes #439.

Release 3.2.10

• Fix arguments to Logger.log_depth to pass depth keyword parameter to #log_depth.
• Minor update in mutable to change the way keyword argument overrides work.
• Update N-Triples/Quads ASCII escapes when writing literals based on proposed RDF 1.2 behavior.
• Fix memory leak on RDF::Util::Cache (#438 – @abrisse)

Release 3.2.9

• Narrow list of valid dates/times/dateTimes based on more strict lexical representations from https://www.w3.org/TR/xmlschema11-2/#rf-lexicalMappings-datetime
• Update CLI filtered option to allow Array or Proc in addition to a single value. This allows, for example, a command to be associated with multiple formats.

Release 3.2.8

• Query#execute and Pattern#execute can take a Solution for bindings, in addition to a hash. This supports passing pre-bound variables from SPARQL.
• When generating docs, add etc/doap files to yard output.
• Fix Dataset#inspect

Release 3.2.7

• Add :uri option to Format,content_type, and uris and to_uri class methods. This allows retrieving the defined format URI for specified formats. (See https://www.w3.org/ns/formats/).
• pass format keyword parameter as option when filtering CLI commands.
• Check for windows drive letter to not confuse it with a URI scheme (windows platform only).

Release 3.2.6

• In Temporal#to_s, set @string if it is nil.
• Reset the string representation for Time values having an hour > 23.
• Temporal#adjust_to_timezone! can certainly take a Literal::DayTimeOffset, in addition to a String.
  Treat the empty string as nil, to remove the timezone.
• Add Solutions#variable_names= to override automated variable name count.
• Add Solutions#== and Solutions#eql?` to test solutions including variable names.

Release 3.2.5

• Adds Temporal literal as superclass of Date, Time, and DateTime.
  • Adds #adjust_to_timezone (and #adjust_to_timezone!) based on XPath function. Takes either a [+1]HH:MM or an xsd:dayTimeDuration restricted to hours and minutes.
  • Adds <=> comparison operator.
  • Adds #year, #month, #day, #hours, #minutes, and #seconds accessors.
  • Add and subtract temporals with each other and durations, per XPath/XQuery functions spec.
• Updates to Date literal:
  • Object base is now ::DateTime instead of ::Date to record and manipulate timezone.
  • Better conformance to XSD and XPath specs.
• Updates to DateTime literal:
  • Better conformance to XSD and XPath specs.
    *Add XPath math functions and constants to Literal::Numeric. PI, #exp, #exp10, #log, #log10, #sqrt, #sin, #cos, #tan, #asin, #acos, #atan, #atan2.

Release 3.2.4

Vocabulary representation

• When reading a vocabulary, don't skip non-english literals.
• When writing a vocabulary, use language-map form for language-tagged literals with any in english serialized as the first entry of the map,
• Remove more redundant string freezes.
• Fixes #432.

Documentation

• Document and parse datatype/language maps as part of Term attribute definitions.
• Update documentation links to use gh-pages, and add action to publish gh-pages from Yard docs.
• Improve Vocabulary DSL documentation.
• Add Yard tag to prevent parsing vocabularies if :noDoc is set.

Other

• Exclude '_' and '-' from PN_LOCAL escapes. Not all reserved characters need to be escaped in SPARQL/Turtle, but they must be unescaped when encountered.
• Improve #quoted? accessor for RDF::Statement, and set it when parsing embedded triples in NTriples/NQuads.
• Update expectation for RDF:URI with a hash argument, due to updates to rspec-mock.
• Update Countable, Enumerable, and Queryable to include their Enumerator classes inline, and remove a separate enumerator.rb to address #433.
