Abstract: Background: Since 2004, Persée operates digital and shared services, and provides digitized heritage content to French scientific community. Supported by the Université de Lyon, ENS de Lyon, CNRS and the French Ministry of Higher Education and Research, Persée is a public and not-for-profit organization. It fulfills three main activities: promoting the back files of scientific publications through the Persée portal (www.persee.fr); developing digitized corpora in partnership with researchers especially in the field of Digital Humanities; clustering large amounts of data to enable Text and Data Mining. Objectives: The aim of the poster is to present the ‘Open Digitized Heritage Content and Services Platform’ developed and implemented by Persée. The poster will underline the key elements of this platform: (1) a range of services driven by the demand of the academic community; (2) an integrated and automated process line (3) an articulation with national and European infrastructures. Content: SERVICES AND COMMUNITIES. Persée aims at different target audiences: the researchers firstly but also the heritage institutions as academic libraries and museums. Persée provides them with a wide range of services to help them to digitize corpora, to ensure XML and semantic encoding and to implement explorative and visualization tools. In this context, Persée brings together digital skills and a pool of software and hardware resources. The poster will be illustrated by some complementary examples: the Persée portal with a broad spectrum and a high visibility (650.000 documents available in Open Access / 30M visits per year) and two digital humanities projects focused on history of art and history of education (ATHAR / BHE). TOOLS. The process line was developed using open source technologies. Its originality relies on its automation and its completeness (digitization, documentation, dissemination of enriched data, online publishing, referencing, long term preservation, quality controls). It may process 1 million pages per year. The poster will focus on the dissemination aspect with different web sites, an OAI-PMH server allowing the harvesting of metadata and data, a set of web services and, a triplestore (data.persee.fr). SUSTAINABILITY. The sustainability is a core issue. Persée provides not only technical answers (use of open standards, interoperability procedures, long term preservation of the digitized heritage content) but also institutional ones. The Persée platform is interconnected with French (Humanum, CollEx) and European infrastructures (DARIAH) to ensure the consistency of the fundings and the adequacy with research framework. Perspectives: One of our objectives is to support a platform allowing the engagement of the research community. Tim Sherratt from the National Library of Australia wrote that “Portals are for visiting, platforms are for building on”. Persée aims to enhance interactions with researchers and reuse of data by its involvement in the semantic web and in the open data and open access movement.
