The KIM project is adopting a new Licensing Policy v3.0, which departs from the previous policy of recommending CDDL. The new policy recommends the GPL-compatible LGPL-2.1-or-later license. KIM infrastructure software will be released under LPGL and this license will be the recommended for content archived in openkim.org. This change brings KIM policy in line with the growing trend toward GPL-compatibility in the open source software community.
In addition, KIM is moving toward adoption of the SPDX family of standards for package license data specification and exchange. By adopting these standards, KIM will be able to record and communicate—in an unambiguous way—the licensing details of the content it provides through openkim.org.
