Base64 is needed when systems can't represent arbitrary binary data directly. For example, XML doesn't allow control characters (depending on XML version) and never allows NUL (character zero), originally because C and C++ systems had to use non-native string handling if you allowed that, but also because it had security implications. If you use RDF/XML (ugh) you would want to encode only the specific properties that had illegal characters in them, and there's no way to encode NUL natively in XML, e.g. � isn't allowed. (not responding to the rest as RDF is all too complicated for me :-) ) -- Liam Quin - XML Activity Lead, W3C, http://www.w3.org/People/Quin/ Pictures from old books: http://fromoldbooks.org/
