PLOS has launched a new journal based on the open source platform
annotum is built on wordpress, and offers a variety of built-for-the-
web publishing affordances. (not much yet on peer review, but it could
be coupled with other tools).
"PLoS Currents is a new publication that aims to minimize the delay
between the generation and publication of new research. The content is
peer-reviewed, citable, publicly archived, and included in PubMed. By
facilitating and accelerating the sharing of new findings and ideas, we
hope that PLoS Currents will accelerate the research cycle itself.
"Authors use the Annotum publishing platform to create their submission,
and are in complete control of the appearance of their article. With
PLoS Currents, submission to publication can take place in a matter of
days and there are no publication fees."
Develop a simple, robust, easy-to-use authoring system to create and
edit scholarly articles
Deliver an editorial review and publishing system that can be used to
submit, review, and publish scholarly articles
Modern platforms such as WordPress provide a model for a successful
eJournal authoring platform – WordPress is extremely simple to set up
and run, with rich, user-friendly web-based editing controls and
easily-extended functionality using plugins. The WordPress platform not
only provides free and open access to source code, with a diverse and
productive ‘ecosystem’ of developers for themes, plugins, and
extensions, but also numerous cheap or free hosting opportunities for
technical and non-technical users alike."
