-<p>DVB's metadata definitions build upon metadata definitions from other organizations and standards by reusing elements from them. For this to be supported by authoring tools, all files referenced by the DVB files must also be available to the authoring tool. Most often, these other organizations also make their files available online. Where this is not the case, we provide copies under the URL root <code>https://dvb.org/3rd-party/</code>. DVB provides these files for completeness, and they are not to be considered canonical. If, for any of them, you are aware of an official online location that could be referenced instead, please contact us at&nbsp;<a href="mailto:webmaster@dvb.org">webmaster@dvb.org</a>. For convenience, all necessary metadata definitions from other organisations (whether available from their originating organization or from the DVB website) are also listed in the XML catalog files and included in the&nbsp;<a href="/metadata/DVB.zip">complete DVB metadata ZIP archive</a>.</p>
