« Perséides » is a label used to identify digital, online accessible and featured corpora. These result from a collaboration between research teams which define the scope and operating methods of the project and Persée, which provides its platform and documentary and IT expertise. Launched as an experiment in 2015, the first Perséides were launched in 2017 and will become a generic model early in 2018. They have common characteristics and features: corpus digitization, structure and semantic encoding, dissemination through a dedicated website, deployment of specific navigation and visualization tools and backup.
ATHAR aims to provide reports, scientific literature and photographic archives about Arab art monuments in cities in the Mediterranean basin, enhanced by TEI toponym indexing.
The first phase of the project focused on the city of Cairo. Following the model of the Commission des Monuments Historiques in France, a committee was created in 1881 in Cairo to inventory, describe and restore Islamic and Coptic monuments in Egypt. The reports of this committee consist of 41 volumes published in Cairo between 1882 and 1953, totalling 8,000 pages and nearly 800 plates (photographs, maps and drawings).
For art historians and historians working on the historiography of Islamic art, the history of restoration and heritage, these reports constitute a unique and important source, not only because of the wealth of data they contain (number of monuments described, quality of architectural and historical information, technical documentation on restoration projects, prosopography of the actors, etc.), but also because of the significance of the information they contain.) and the gradual disappearance of these buildings during the 20th and 21st centuries. Of the 800 monuments identified since 1880, 300 no longer exist today. This corpus sometimes gathers the only documentation still existing on disappeared, highly deteriorated or radically transformed monuments.
In particular, this type of corpus raises processing difficulties in terms of identification and indexation, due to the multiple variants resulting from the transliteration of Arabic toponyms. The laboratoire InVisu (USR 3103 CNRS/INHA) has established a reference system for Cairo’s monuments, n the form of a concordance table that identifies and aligns variants of monument names, and allows buildings to be identified, described and located. The repository is hosted by Humanum.
The BHE, Historical Library of Education,, aims to make available a 
variety of resources concerning education, in a heritage and scientific perspective. Administrative documentation, journals, books and archives are backed by a set of specific tools: thesaurus, cartography and index.
The work on the history of educational policies and institutions developed over the past twenty years has relied comprehensively on manual reviews of serial, administrative and printed sources. The richness and complexity of these documentary deposits are both an asset and a constraint due to the difficulties of their accessibility and processing. The objective of the BHE is to ensure linking of complex hypotheses on a large scale concerning the forms of organization of an educational system that is both centralized and characterized by the originality of its achievements at the local level, and to participate in the understanding of the phenomena of structuring the educational system, through the detailed study of regulations, institutions, actors and curriculae.
The documentary collection at the heart of the project comes partly from the Bibliothèque Diderot de Lyon, which is a CollEx component in the field of education, and a partner of the Bibliothèque nationale de France. It also comes from the ENS Publishing Fund, the heirs to the NPRI. Finally, it is supported by the education collections held in the National Archives (in particular the F17 and AJ 16 series). The first digitized corpus consists of recent and historical scientific publications (journals, monographs, articles and conference contributions), administrative literature, grey literature and archives.
