About this site
The reference generator, prettyxsd, and this site were made by Giles Antonio Radford.
The code that generates the site was written with the help of AI. The documentation itself is not AI-written: every element, type, description and line of source shown here is taken directly from the official OpRa reference schemas on GitHub. OpRa's NeTEx and SIRI parts are shown at the NeTEx and SIRI versions OpRa itself uses, which can differ from the NeTEx 2.0 and SIRI 2.3 pages elsewhere on this site.
This is an independent reference, not an official CEN publication.
