语言说明符总的说来并不是该语句的特性（这就是为什么国际化没有将RDF 转换成四元组而是三元组系统的原因）。
The language specifier is not a property of the statement as a whole (which is why internationalization does not turn RDF into a system of quads rather than triples).
当然，你可能也会用到四元数转换的“常规”表示法。
Of course, you'll also need to be able to convert from "conventional" representations to quaternions.
