Ambra is an innovative Open Source platform for publishing Open Access research articles. It provides features for post-publication annotation and discussion that allows for a "living" document around which further scientific discoveries can be made. Ambra uses a semantic repository which provides a way to store all content as RDF triples. Ambra is freely available and allows scholarly publishers, societies, universities, or research communities to publish Open Access journals economically and efficiently. The platform is in active development by the Public Library of Science (PLoS) and is licensed under the Apache License, Version 2.0.
