Release 3.0.1

• Can't lookup a vocabulary from a BNode.
• Make it so that if Format.for is called with no selection criteria, it returns nil rather than all formats (linter issue).

Release 3.0.0

Major changes since 2.2:

• Removed deprecated interfaces
  • Remove deprecated #to_hash and #to_a.
  • Remove deprecated grammar option to Node.uuid.
  • Fix emergent issue on named graph transactions to coercing triple to statement including graph name.
• Support vocabularies with anonymous values, which are treated either as Lists or Terms. This allows serialization of SKOS vocabularies with anonymous Concepts and OWL vocabularies which use owl:unionOf on anonymous classes.
  • Improve vocabulary documentation with examples.
  • Add :isDefinedBy shortcut to rdfs:isDefinedBy.
  • Add skos term accessors.
  • Term inverseOf accessor should be for owl:inverseOf, not schema:inverseOf.
  • Update options for Vocabulary.property and Vocabulary.ontology.
  • Allow Terms to be defined with a nil or no name, being an anonymous BNode.
  • Implement #to_ruby for RDF::Vocabulary::Term. This generates Ruby source to re-create the state of the object.
  • Improvements and tests for vocabularies with anonymous and List content.
  • Update built-in vocabulary syntax.
  • Add more OWL accessors.
  • Make vocabulary processing more lightweight by retaining original strings and deferring transformation into terms until they are accessed.
  • Added Term#properties to give a transformation of Term#attributes with values turned into RDF::Term instances.
  • Added Term#attribute_value to do this on a per-attribute basis.
  • Added Term#restriction? accessor to look for terms which are owl:Restriction.
  • Updated Term#respond_to? to base this mostly on type of term, in some cases on presence of attribute.
  • Make sure expand_pname validates the resulting URI and raises an error if invalid.
• Add filtering from Format.for to Format.each to find all formats that match certain criteria.
  • Add support for content-type wildcarding when filtering formats.
• Implement Query#variables and similar accessors to be semetric with Query::Pattern; also includes a variable graph name.
• Remove df.rb (quite archaic).
• Make sure Literal subtypes get non-nil @object values.
• Remove pending on some N-Triples tests that had a JRuby issue with #to_ary.
• Support Ruby 2.5

Release 2.2.12

Change Dataset#each_statement to Dataset#each to keep with description in RDF::Enumerable. This broke rdf-do, and the general contract described in RDF::Enumerable which datasets should implement.

Release 2.2.11

Make sure that writer doesn't raise WriterError because of error count established when started.

Release 2.2.10

• Allow RDF::Vocabulary#send and #public_send (@no-reply)
  • We were previously undefining :send and :public_send. This closes #356.
• Performance Improvements (@jperville)
• Don't attempt to build URIs from Class names (@no-reply)
  • RDF::Vocabulary would previously attempt to build URIs from Class names when no URI was present for the vocabulary class. We now use a null relative URI instead.

2.2.9

CLI:

• Fix option callback arguments for specific readers and writers to include options.
• Handle CLI argument callback with arity 0 or > 2.
• Take some steps to keep CLI option data from being modified.
• Do some sanity normalization of CLI output messages hash.
• Fix CLI usage.

Documentation:

• Change some rubyforge references.

Release 2.2.8

Update CLI processor:

• Add :control field to CLI::Options for HTML layout
• Allow CLI::Options#call to provide options along with arg based on arity of receiver (this allows options to add other options).
• Extract most built-in options to structure.
• CLI.options does not use callback any longer. It takes an argv parameter and figures out commands from there.
• CLI.commands now accept a format named parameter; if used with :json, it returns a JSON structure
• CLI::Options now implements #to_hash.
• Add args accessor to OptionParser to retain arguments after options have been extracted.
• Note potential addition of :messages component to options passed to command lambda.
• Note that status updates should be logged (info) rather than output to $stdout.
• Add required parameter/option to Option to indicate that the option must be specified.
• Overload RDF::CLI.options to also return a JSON representation of options in addition to normal processing.
• Make class_name option required for Vocabulary CLI options.
• In CLI.parse if using evaluated input, take sample to use if no format is specified.
• Make sure CLI logger is set in options, using that from option_parser if not provided explicitly.
• In CLI runner, if messages are set, display them. This is in preference to text formatting in the command.
• Change CLI::Option#required to CLI::Option#use with states :disabled, :removed, :required, and :optional.
• Allow commands to override option use using option_use.

Release 2.2.7

Fix broken RDF::Node.uuid. Note that the :grammar option is deprecated and provide some documentation for the :format option. Requires that either uuid or uuidtools gems be loaded.

Release 2.2.6

• In Reader.open, only use format to find a concrete reader, not other options. This allows the content-type and actual file content to be used to select a reader, in preference to filename and extensions.

Release 2.2.5

• Require 'openssl', as OpenSSL is used as a constant.
• Ensure that finding the path from a filename always results in a string (e.g., when file_name is a pathless URI).
