semantic_record is designed to use data that is stored in an sesame triple-store whitin an rails application. So usage an behavior are highly similar to activerecord.

A simple model implementation would look like:

class Genre < SemanticRecord::Base
  self.base = "http://example.org" # for setting the base URI
  self.uri = "http://example.org/music#Musicgenre" # for overriding guessing from classname and base
def some-method
end
end

You can use find to access instances of the given class:

g = Genre.find   # gets all instances
g = Genre.new('http://example.org/music#Funk')  # gets an specific instance

Also dynamic finders are avaliable on datatype properties:

class Genre < SemanticRecord::Base
g = Genre.find_by_artist('John Doo')
