.to_rdf_options(options = {}) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Convert options hash into a string for librdf. What it does:

1) Convert boolean values into 'yes/no' values
2) Change underscores in key names into dashes ('dhar_ma' => 'dhar-ma')
3) Join all options as "key='value'" pairs in a comma-separated string

Examples:

to_rdf_options {:key => true, "key_board" => 3}
# => "key='yes',key-board='3'"
