RDF.rb storage adapter skeleton

This is a skeleton repository to create your own RDF.rb storage adapter. It's designed to get you up and running with a new backend as quickly as possible, so that you can have working tests right away, allowing you to develop iteratively.

See for an overview.

Getting started:

  1. Ensure you have the requirements below.
  2. Run the tests. You'll get a lot of NotImplementedErrors
  3. Find and fix the TODO markers in lib/rdf/myrepository.rb.
  4. Find and fix the TODO markers in spec/my_repository.spec. You may not need to do this if your repository needs no arguments to new().
  5. Run the tests! Man, you're awesome!
  6. Iterate and improve! If your backend is better served by replacing some of the many methods that an RDF::Repository implments, replace them.

To run tests, run:

spec -cfn spec/my_repository.spec


You'll need the rdf, rdf-spec, and rspec libraries. The easiest way to install these is via RubyGems.

$ sudo gem install rdf rdf-spec rspec



Please post questions or feedback to the W3C-ruby-rdf mailing list.

If you're unfamiliar with public domain, that means it's perfectly fine to start with this skeleton and code away, later relicensing as you see fit.
