DESCRIPTION:La conférence JRES existe de puis 1995 ( [ https://archives.jr
 es.org/ | https://archives.jres.org/ ] ) et le comité d''organisation de l
 a prochaine édition de la conférence a en charge l'archivage pérenne des
  contributions passées. 
\n
\nNous envisageons de verser ces données dans
  HAL\, mais nous n'en sommes qu'à l'étape de découverte de HAL\, son fon
 ctionnement et son API. 
\n
\nNous proposons un échange de type questions/
 réponses avec Laurent Jonchère (gère [ https://univ-rennes.hal.science/ 
 | https://univ-rennes.hal.science/ ] ) pour nous aider à découvrir les po
 ssibilités de HAL\, les difficultés éventuelles\, son API.
