Redland - RDF Application Framework - Ruby Interface

Installing the Redland Ruby interface

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
  make check # optional

To install it system wide (this is optional) do this as root:

  root# make install

The Ruby interface has been tested with Ruby 1.8, 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.

Redland Ruby API Introduction

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.

Testing the Redland Ruby interface

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

NOTE: ONLY file: URIs will work with at present.
