What it does
A vocabulary of its author's own, used from CDS as using urp from 'urp-vocab' and applied as @urp.display and five further terms. Whether its terms reach the OData metadata is not established: its readme names the terms and the widget types but says nothing about registering the vocabulary with the compiler, nothing about cds.cdsc.odataVocabularies, and nothing about what reads the terms. Its declared repository, github.com/your-username/urp-vocab, is an unedited placeholder, so the package's own files are the only record there is.
Remaining work
Read the published package's files before treating it as an answer here. On what is written down, it is a vocabulary definition and not a translation path.
