One might think of the metadata semantics shared within DC-Multilingual to be, in some sense, independent of any particular language, hence universal. The versions of Dublin Core elements in various languages should share a single namespace. This will need to be discussed and ratified by the Dublin Core community as a whole. The descriptive names and element definitions are meant to be read primarily by humans, the tokens primarily by machines. The tokens look like English words but stand for universal elements.
Universal elements can have interchangeable names and definitions in multiple languages.
To express schemas in other languages, however, we need support for human-readable descriptive names as well. For now we will keep these separate so that we more easily can change them when we know what is required. Perhaps element definitions could be dynamically extracted from an RDF file to an HTML file, or vice versa. This is clearly a question for further research. Either way, what the namespace name points to can change over time, so we can go ahead and write metadata with confidence.
