RDF for SQLite
RDF for SQLite is a container gem for getting the simplest RDF-based applications off the ground. It uses quite a few modular gems and fixes a little inconsistency between RDF.rb and ActiveModel. The gems are:
-
rdf
-
rdf/ntriples
-
data_objects
-
do_sqlite3
-
rdf/do
-
spira
-
active_model
This basically boils down to RDF.rb + ActiveModel + Spira + SQLite3 to create a pretty straightforward repository, serializer, parser, and ORM.
To get a simple model built, this will work:
class Person
include RDFForSQLite
# Choose a useful base URI
base_uri "http://example.org/people"
property :name, :predicate => FOAF.name
validate :presence_of_name
protected
def presence_of_name
assert_set :name
end
end
A full example using Sinatra looks like this:
Note on Patches/Pull Requests
-
Fork the project.
-
Make your feature addition or bug fix.
-
Add tests for it. This is important so I don’t break it in a future version unintentionally.
-
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but
bump version in a commit by itself I can ignore when I pull)
-
Send me a pull request. Bonus points for topic branches.
