Advanced Open Access Publishing Model

There are two main modes of open access publishing – Green Open Access, where the author has the right to provide free access to the article outside the publisher's web site in a repository or on his/her own website, and Gold Open Access, where articles are available for free download directly from the publisher on the day of publication.

Opening of content and data, however does not necessarily mean "easy to discover and re-use". The Biodiversity Data Journal proposed the term "Advanced Open Access" to describe an integrated, narrative (text) and data publishing model where the main goal is to make content "re-usable" and "interoperable" for both humans and computers.

To publish effectively in open access, it is not sufficient simply to provide PDF or HTML files online. It is crucial to put these under a reuse-friendly license and to implement technologies that allow machine-readable content and data to be harvested and collated into a big data pool.
