Connie Release 0.0.1 (January 5th 2009)
Copyright: Pius Uzamere © 2009 License: The Lesser GNU Public License
Connie is a Ruby library that implements SPARQL given a parse tree of a SPARQL query and a set of RDF triples. Implements SPARQL properties as a set of constraints. The constraints are executed by Gecode/R, a Ruby bridge to Gecode, an open source library for constraint programming written in C.
- Connie can handle simple, univariate triple patterns: When finished, this library will have a full test suite and can serve as a maintainable reference implementation of a SPARQL engine in Ruby. Currently, only very basic queries are supported. Please see the spec suite for the latest usage examples or check out the documentation for more details.
- Make Sure You've Got the Dependencies installed
sudo gem install gecoder-with-gecode
Clone the Repository and Install the Connie Gem from Source
git clone git://github.com/pius/connie.git cd connie gem build connie.gemspec sudo gem install connie
Require the gem in your code, play with it
For usage, the best thing is to click through the documentation. I tried to make it really thorough. If you need more guidance, check out the specs, which demonstrate precisely how to feed Connie a SPARQL query parse tree and run the engine.
Fork my repository, make some changes, and send along a pull request!
The best way to contribute is to add a unit test for a specific SPARQL parse tree and then tweak the code such that your new test case plus all the others pass.
