Dear all, DCMI has published the source code of the script it uses to generate RDF schemas and Web documents when updating DCMI metadata terms. Maintainers of other vocabularies may find these interesting. For DCMI, we'd like to tweak the scripts to generate Web pages with RDFa, and we are very open to any other suggestions on how we might improve our publication methods. See the announcement below for more details...
