def Turtle::identifier(id)
  raise "Illegal identifier #{id}" if id != Turtle::mangle_identifier(id)
end

.mangle_identifier(s) ⇒ Object

Replace letters/symbols that are not allowed in a Turtle identifier (short hand URI). This should be the definite mangler and replace the ones in bioruby-table and bio-exominer. Manglers are useful when using data from other sources and trying to transform them into simple RDF identifiers.
