Nature (nature.com) will be introducing Scientific Data, an open-access, online-only publication for descriptions of scientifically valuable datasets, starting in 2014.

From the Nature post:

Scientific Data, ” introduces a new type of content called the Data Descriptor, which will combine traditional narrative content with curated, structured descriptions of research data, including detailed methods and technical analyses supporting data quality. Scientific Data will initially focus on the life, biomedical and environmental science communities, but will be open to content from a wide range of scientific disciplines. Publications will be complementary to both traditional research journals and data repositories, and will be designed to foster data sharing and reuse, and ultimately to accelerate scientific discovery.

Scientific Data will launch in Spring 2014 and be open for submissions in Autumn 2013. Sign up for our e-mail alerts or follow us to stay informed”
