Given that this is the PLoS technology blog, I thought that it would be good to start with an overview of the underlying PLoS ONE architecture. PLoS ONE will be launched on the TOPAZ application framework. TOPAZ aims to create a publishing platform to facilitate the shift of the scientific and medical communities from subscription based journals to an Open Access online commons.
The core of TOPAZ is a digital information repository called Fedora (Flexible Extensible Digital Object Repository Architecture). Fedora is an Open Source content management application that supports the creation and management of digital objects. The digital objects contain metadata to express internal and external relationships in the repository, like articles in a journal or the text, images and video of an article. This relationship metadata can also be search using a semantic web query languages. Fedora is jointly developed by Cornell University’s computer science department and the University of Virginia Libraries.
The metastore Kowari will be used with Fedora to support Resource Description Framework (RDF) http://en.wikipedia.org/wiki/Resource_Description_Framework metadata within the repository.
The PLoS ONE web interface will be built with AJAX.
