Recommended rdf usage in Ruby on Rails

I'd like to publish rdf in my rails apps. What's the right way t开发者_开发百科o do it?

(For people who are interested in working with actual RDF data, please see The State of RDF in Ruby.)

The short answer to your question: You're looking for respond_to. In general, you'd write something like:

class PeopleController < ApplicationController::Base
  respond_to :html, :rdf

  def index
    @people = Person.all
    respond_to do |format|
      format.html
      format.rdf { convert_to_rdf(@people) }
    end
  end
end

Of course, you'll have to write 'convert_to_rdf'. You might find that RDF.rb is helpful for that.

Have you tried ActiveRDF? Quoting:

ActiveRDF is a library for accessing RDF data from Ruby programs. It can be used as data layer in Ruby-on-Rails, similar to ActiveRecord (which provides an O/R mapping to relational databases). ActiveRDF in RoR allows you to create semantic web applications very rapidly. ActiveRDF gives you a Domain Specific Language (DSL) for your RDF model: you can address RDF resources, classes, properties, etc. programmatically, without queries.

• ActiveRDF can be used with various RDF stores, adapters to other stores can be written very easily.
• ActiveRDF uses convention over configuration, which means it works very nicely in 90% of the cases.
• ActiveRDF is open source, released under the LGPL license.

For those looking at this issue in the future: the gem rdf-serializers uses active_model_serializers to easily serialize to RDF.
