Overview

An ActiveModel compliant ObjectGraphMapper for RDF data.

Models graphs as ‘RDFSources` with property/attribute configuration, accessors, and other methods to support Linked Data in a Ruby enviornment.

Examples:

modeling a simple resource

class Thing
  include  ActiveTriples::RDFSource
  configure :type => RDF::OWL.Thing, :base_uri => 'http://example.org/things#'
  property :title, :predicate => RDF::DC.title
  property :description, :predicate => RDF::DC.description
end

obj = Thing.new('123')
obj.title = 'Resource'
obj.description = 'A resource.'
obj.dump :ntriples 
 # => "<http://example.org/things#123> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.w3.org/2002/07/owl#Thing> .\n<http://example.org/things#123> <http://purl.org/dc/terms/title> \"Resource\" .\n<http://example.org/things#123> <http://purl.org/dc/terms/description> \"A resource.\" .\n"

.class_from_string(class_name, container_class = Kernel) ⇒ Class

Converts a string for a class or module into a a constant. This will find classes in or above a given container class.

Examples:

finding a class in Kernal

ActiveTriples.class_from_string('MyClass') # => MyClass

finding a class in a module

ActiveTriples.class_from_string('MyClass', MyModule) 
# => MyModule::MyClass

when a class exists above the module, but not in it

ActiveTriples.class_from_string('Object', MyModule) 
# => Object

Parameters:

  • class_name (String)
  • container_class (defaults to: Kernel)

Returns:

  • (Class)
