In this presentation, we will describe the development of a proof of concept (POC) which will allow the linking of publications deposited in HAL, the French open archive (https://hal.archives-ouvertes.fr/) developed by the CCSD (center for direct scientific communication https://www.ccsd.cnrs.fr/en/home/) and data or datasets deposited in NAKALA (https://nakala.fr/) developed by Huma-num (https://www.huma-num.fr/), the French research data repository for SSH data. We will highlight how we have addressed some technical issues in order to build the POC, and the possible re-use of the results of its achievement.
