SWORD

The Semantic Web on Rails Development (SWORD) plugin eases the development of semantic web applications. SWORD is a ruby-on-rails that provides scaffolding based on semantic web information.

Overview

SWORD allows you to generate a controller, model and views for managing one type of semantic web data, such as a foaf:Person. The controller offers actions such as list all people, search a person, fetch online semantic web information about people, and show/edit/update specific people. The generator also creates an ActiveRDF model for foaf:Person and basic views for each action. Based on these files automatically generated files, the application developer can further configure, enhance, and develop his application.

Example: a foaf editor and viewer

$ gem install --include-dependecies rails
$ gem install --include-dependecies activerdf-rdflite
$ rails foafapp
$ cd foafapp
$ ./script/plugin install http://sword....... (not yet online)
$ ./script/generate scabbard person foaf http://xmlns.com/foaf/0.1/
$ ./script/server

Done! The application runs and is fully functional, allowing users to fetch foaf data from the web, to search, display, and edit information about people.

Generated files

The scabbard generator constructs the following files (for the example of foaf:Person):

app/controllers/people_controller.rb
app/models/person.rb
app/views/people/edit.rhtml
app/views/people/list.rhtml
app/views/people/new.rhtml
app/views/people/show.rhtml
