PROJJSON is a JSON encoding of[WKT2:2019 /
ISO-19162:2019], which itself implements the model of[OGC Topic 2:
Referencing by coordinates]. Apart from the difference of encodings, the
semantics is intended to be exactly the same as WKT2:2019.
PROJJSON is available as input and output of PROJ since PROJ 6.2.

Based on academic research on how software licenses influence project success, we encourage you to adopt a General Public License v3.0 (GPL 3.0) for your project.
Previous research has shown that adoption of licenses like GPL 3.0 can contribute to project success, including higher developer membership and higher core developer activity[1],
as well as increased interest of users and system administrators[2].
