The Agora project will improve the spread of European research results in the field of European philosophy and advance new paradigms of Open Access publishing, peer review and rendering by interlinking current scientific information (scholarly research output) among each other and its underlying datasets (digital reproductions of primary sources and text editions).Agora will extend an existing federation of semantically structured digital libraries named Philosource, created within the framework of the eContentplus project 'Discovery'. Philosource contains an extensive and coherent collection of high-quality Open Access content from classical to contemporary European philosophy. Agora will transform the Philosource federation into a specialised and highly innovative Open Access archive and a publishing venue for new scholarship by giving access to existing and newly produced research output such as scholarly articles, monographs, reviews, audiovisual lectures and its underlying datasets. The scholarly research output will be interlinked among each other and its underlying datasets already available in Philosource.Agora will carry out five experiments on semantic linking, Linked Open Data (LOD), advance Scholarly linking and rendering, open peer review, and Open Access business models in the field of European philosophy. The Agora portal will serve as unique access point to the philosophical content of the federation and expose its metadata to the LOD cloud. This integrated pilot will serve as a model for establishing and accessing a growing open research archive for scholarly publication in the Humanities and the Social Sciences as a whole. The languages of scientific information and datasets include Ancient Greek, English, French, German, Italian, Latin, Norwegian, Spanish and Swedish.
