Currently, EMOZ is designed for individual declarations only. The system requires one person to declare ownership and accept the legal declaration when issuing a certificate.
If a work has multiple authors, there are a few options:
One author can register the file on behalf of the group, assuming everyone agrees. That person’s name will appear in the certificate and metadata as the declarant.
You can also mention joint authorship directly in the filename or within the file itself (e.g., in a title page, footer, or metadata), since EMOZ does not parse or interpret the file content.
Technically, two people cannot register the exact same file, because the file’s fingerprint (SHA-256 hash) must be unique in the system. This ensures immutability and prevents duplicate claims.
Support for explicit group authorship may be introduced in future updates. For now, we recommend coordinating as a group and having one designated author register the certificate when the file is co-created.
