Module: ActiveFedora::Rdf::Properties

Extended by:
Deprecation
Included in:
ActiveFedora::RDFDatastream, List, Resource
Defined in:
lib/active_fedora/rdf/properties.rb

Overview

Implements property configuration common to Rdf::Resource, RDFDatastream, and others. It does its work at the class level, and is meant to be extended.

Define properties at the class level with:

property :title, predicate: RDF::DC.title, class_name: ResourceClass

or with the ‘old’ style:

map_predicates do |map|
  map.title(in: RDF::DC)
end

You can pass a block to either to set index behavior.

end

#property(name, opts = {}) {|index| ... } ⇒ Object

Registers properties for Resource-like classes

Parameters:

  • name (Symbol) —

    of the property (and its accessor methods)

  • opts (Hash) (defaults to: {}) —

    for this property, must include a :predicate

Yields:

  • (index) —

    index sets solr behaviors for the property
