Nate, you are right, but there's a catch. Let me tell a story. When we 
were creating the RDF for RDA we decided to use the RDA name for the 
term in the RDF property. In part this was so that JSC could look at the 
RDF in the Metadata Registry and see the correlation with their work. 
This, however, resulted in teratologies like:

http://rdvocab.info/Elements/noteonChangesinContentCharacteristicsExpression

People complained.

In creating the RDF for FRBRer, Gordon Dunsire decided to use codes 
instead. At some point, codes will be displayed to humans as friendly 
language terms, but early developers end up seeing the URIs with the 
codes themselves. So what they see is:

http://iflastandards.info/ns/fr/frbr/frbrer/P3086

People complained.

The upshot is that it doesn't matter whether it's a code, a language 
term, or a randomly generated set of characters. What matters is whether 
YOU understand it. MARC terms have become a language because people 
understand the codes directly, without any translation to natural 
language. We know that in the future cataloging interfaces will show 
catalogers something that they, presumably, understand. We also need to 
help early developers and reviewers get a grip on what they are looking 
at. I find it interesting/odd that so many RDF or OWL ontologies do not 
display natural language labels in the place of URIs. Even though the 
mantra is that URIs are for machines, we keep showing them to people.

kc
p.s. The BIBFRAME vocabulary pages are very nice, and in fact COULD mask 
URIs that don't use terms. But I bet someone would complain about how 
hard it is to remember the URL for the page. :-)

And all MARC specimens of RDA data abound with verbiage although codes do exist, as for example in the 33X's. One important aspect  is international exchange and multilingual catalog interfaces, the other is most certainly consistency. As you point out, software should of course be able to catalogers with comfortably inputting codes with not having to know the numbers or acronyms literally, and OPAC software can display whatever text is found suitable for the situation at hand. Imstead, English language verbosity and loquatiousness abound in the data, with excessively long labels in XML designs to make your head spin and at the same time increasing the probability of errors, i.e.
