RDF::Microdata reader/writer

Microdata parser for RDF.rb.


RDF::Microdata is a Microdata reader for Ruby using the RDF.rb library suite.


RDF::Microdata parses Microdata into statements or triples.

Install with 'gem install rdf-microdata'


Reading RDF data in the Microdata format

graph = RDF::Graph.load("etc/foaf.html", :format => :microdata)


The Microdata editor has recently dropped support for RDF conversion, as a result, this gem is being used to investigate ways in which Microdata might have more satisfactory RDF generation.

Generating RDF friendly URIs from terms

If the @itemprop is included within an item having an @itemtype, the URI of the @itemtype will be used for generating a term URI. The type URI will be trimmed following the last '#' or '/' character, and the term will be appended to the resulting URI. This is in keeping with standard convention for defining properties and classes within an RDFS or OWL vocabulary.

For example:

<div itemscope itemtype="http://schema.org/Person">
  My name is <span itemprop="name">Gregg</span>

Without the :rdf\_terms option, this would create the following statements:

@prefix md: <http://www.w3.org/1999/xhtml/microdata#> .
@prefix schema: <http://schema.org/> .
<> md:item [
  a schema:Person;
  <http://www.w3.org/1999/xhtml/microdata#http://schema.org/Person%23:name> "Gregg"
] .

With the :rdf\_terms option, this becomes:

@prefix md: <http://www.w3.org/1999/xhtml/microdata#> .
@prefix schema: <http://schema.org/> .
<> md:item [ a schema:Person; schema:name "Gregg" ] .

Improve xsd:date, xsd:time, xsd:dateTime and xsd:duration generation from time element

Use the lexical form of the @datetime attribute of the time element to determine the specific type of the generated literal.

Remove implicit RDF triple generation

html>head>title and anchor (a) elements no longer generate triples without @item* properties
