This is built if --with-ruby is given to the configure line, or --with-ruby=ruby1.8 to use a particular Ruby version/program. The standard 'make' at the top level will build it.
You can also compile the Ruby interface by hand as follows:
cd ruby make # optional, but it may require a top-level 'make install # first depending on the operating system and how it # handles shared libraries make check
To install it system wide do this as root (or maybe via sudo make install):
root# make install
The Ruby interface has been tested with Ruby 1.8, 1.6.8, 1.6.7 and 1.6.4 and is alpha quality - it is a bare API and may change a lot. Thanks to Dan Brickley for his Ruby help in getting this first version working.
The Ruby API is an object-based API with the class names and method names flattened into Ruby procedure names like this: librdf_class_method - the same names as in the underlying C API. The object references become Ruby variables.
The example program provided parses an RDF/XML source file into a model. It should be run with two arguments - the URI of the content (as file:/path/to/content) and the parser name (say, raptor):
ruby example.ruby file:../perl/dc.rdf raptor
