Get the CERIF-TG-Tools project in a parallel directory and use it produce the RDF and HTML formats and review the changes.
When the changes are o.k., commit in a new branch in CERIF-Vocabularies and start a pull request there.
Once this pull request is integrated in the master branch, this project will use the CERIF-TG-Tools to process the CERIF XML forms into RDF and HTML and publish them on the euroCRIS website.
