The Open Database Licence (ODbL) is a licence agreement intended to allow you to freely share,
modify, and use this Database while maintaining this same freedom for others. Many databases are
covered by copyright, and therefore this document licenses these rights. Some jurisdictions, mainly
in Europe, have specific rights that cover databases, and so the ODbL addresses these rights, too.
Finally, the ODbL is also an agreement in contract for you to act in certain ways in return for
accessing this Database.
