PLOS has released its Ambra publishing journal software under the MIT License.
Here's an excerpt from the announcement:
This isn’t the first time Ambra was available to those looking for a journal publishing platform. Under continuous development since 2009, Ambra was a monolithic Struts webapp offered as open source since its beginning. In 2012, PLOS began a project to re-architect Ambra as a service-oriented, multi-component stack. PLOS has been actively using, testing, and improving these new components in its journal platform since 2013, and in early 2016 we replaced the legacy Ambra webapp in its entirety. Having sorted through some minor license incompatibilities and put together documentation and quickstart guides, we’re proud to release Ambra under the MIT License
