1.0.1

  • LC version of HTML+RDFa
    • Remove support for @value
    • Prefer @content to @datetime

1.0.0

  • 1.0 release!

0.3.20

  • Change rdfa:Prototype/rdfa:ref to rdfa:Pattern/rdfa:copy. Feature now called Property Copying instead of Reference Folding.

0.3.19

  • Generate UnresolvedTerm and UnresolvedCURIE as indicated. UnresolvedCURIE only generated for SafeCURIEs.
  • Perform basic sanity checking before emitting triples. Validation is too strict for most usage.
  • Add HTML5 logic to remove unwanted @rel and @rev items.
  • Make reference folding standard, under option control.

0.3.18

  • Fixed additional incomplete-triples bug with typed resource
  • Added experimental support for rdfa:copy

0.3.17

  • Added rdfa:PrefixReDefinition warning.

0.3.16

  • Fix step 11 when there is @resource, @href and @src but not @rel or @rev to not also depend on the state of incomplete triples. This addresses an odd Drupal case.
  • respec shared examples updates to match rdf-spec 0.3.11

0.3.15

  • Add support for @role attribute.
  • Processing defaults to HTML, rather than XML, unless XML is explicitly detected.
  • Process embedded RDF:XML, if RDF::RDFXML is loaded, and a RDF/XML is detected.
  • Process alternate readers where content is contained within a <script> tag, based on the @type attribute. This is commonly used for N-Triples and Turtle embedded in HTML.
  • If @itemscope detected, and RDF::Microdata is loaded, process embedded microdata.

0.3.14

  • Support for rdf:HTML literal.

0.3.13

  • Parse any include RDF/XML if RDF::RDFXML is available.
  • Add support for extracting RDF from <script> elements.
  • Places triples in a named graph if the script has an @id attribute.

0.3.11

  • Up to date with RDFa Proposed Recomendation versions of specs.
  • Fix problems with @resource=[] or @about=[], which should be ignored and use the next most appropriate attribute.
  • Remove support for @data, which was previously a synonym for @src in HTML5.
  • More robust detection of XHTML1 if version is rdfa1.0
  • Support change to remove @rel/@rev elements that aren't CURIES or IRIs when in the presense of @property

0.3.10.1

  • Fix case where @datatype and @property are present, but @datatype is empty. (TC 290)

0.3.10

  • Updated to Candidate Recommendation of drafts:
  • change profile to context to conform with change in use in RDFa 1.1.
  • Change :expand\_reader option to :vocab\_expansion, to conform with RDFa Core 1.1 definition.
  • Changed :processor\_graph to :processor\_callback and added :rdfagraph option, taking either or both of :output and :processor.
  • Better error recovery is there is no document root.
  • Updates to CURIE definition, Term resolution (use @vocab first), and Error/Warning generation in the processor graph.
  • rdfa:usesVocabulary changed to rdfa:hasVocabulary.
  • Tolerate errors in vocabulary download when missing.
  • Change SafeCURIEorCURIEorIRI to not include term.
  • Remove TERMorCURIEorAbsIRIprop, as it doesn't seem necessary.

0.3.9

  • Updated to latest working drafts:
  • In reader:
    • Don't default xhtml1 and rdfa1.1 in parser; depend on host_detect.
    • Use separate context documents for XML, XHTML and HTML.
    • Remove Facet gem, which was causing problems with Active Record.
    • Added full support for HTML5 <time> element.
    • Added support for HTML5 <data> element with @value attribute to create a plain literal with possible language.
    • Change vocabulary expansion rules to use OWL 2 RL entailment.
    • Terms can now include a '/', to allow for use with @vocab where the class/property is a relative IRI.
  • In writer:
    • Don't serialize using XHTML initial context, as it is not used universally.
    • Simplify Haml templates using latest RDFa attribute semantics

0.3.8

  • Remove hard dependency on Nokogiri. Use it if it is available, otherwise fallback to REXML.
    • JRuby uses REXML due to some implementation issues with the pure-java implementation of Nokogiri.
  • Support for RDF Lite 1.1
  • Add support for @property doing object references if used with @href/@src/@resource (but no @rel)
  • Add support for @property chaining if used with @typeof.
  • Change @typeof behavior to add type to object, not subject, unless used with @about.

0.3.7

  • RDF.rb 0.3.4 compatibility.
  • Changed @member to @inlist.
  • Added format detection.
  • Serialize lists.
  • Change @src to be like @resource for RDFa 1.1 (still like @about for RDFa 1.0).
  • Fix writer template issues with muti-valued properties

0.3.6

  • Sync with changes to RDFa 1.1 spec:

    • Implemented Reader#expand to perform vocabulary expansion using RDFS rules 5, 7, 9 and 11.
    • Support for RDF collections (rdf:List) using @member attribute.
    • Implemented :expand option to reader, which allows normal use of reader interface without requiring the use of the #expand method.
    • Add caches for popular vocabularies to speed load time.
    • Add :vocabulary_profile as Reader option to allow for use of persistent vocabulary caches.
    • Performance improvements by evaluating debug statements in block only when debug enabled.

0.3.5

  • Updates to writer necessary for structure-data.org linter.
    • Support for type-specific templates and types matching a regular expression.
    • Allow #find-template to be overridden in subclasses.
  • In reader

    • Fixed bug where @typeof was ignored in the root element.

0.3.4.2

  • Fix Writer output for multi-valued properties when there is no :property_values Haml template.
  • Simplify templates by using pre-rendered CURIEs.

0.3.4.1

    • Profiles are processed left to right
    • Detect 1.0 using @version
