ESA Software Community License
The applicable versions of the ESA Software Community License (ESCL) are provided on ESSR.
The ESCL is available in three different flavours:
- ESCL Strong Copyleft - v2.3, with Copyleft clause (cl. 3.1)
- ESCL Weak Copyleft - v2.3, with Copyleft clause (cl. 3.1), but allowing certain Combinations (cl. 3.2.4)
- ESCL Permissive - v2.3, with No Copyleft clause (cl. 3.1)
A commentary describes the rationale and license details of the ESA Public License (ESA-PL), which differs from ESCL only in that there is no restriction to the Territory of ESA Member States.
