ITAR defines export as transferring an article or technical data (§ 120.7).
Technical data, by definition, is not in the public domain (§ 120.10.5).
DEFCAD claims the files are in the public domain, i.e., available in bookstores (§ 120.11.1) and libraries open to the public (§ 120.11.4). So they cannot qualify as technical data to satisfy the export requirement.
