The astronomy, astroparticle and particle physics communities are brought to- gether through the ESCAPE (European Science Cluster of Astronomy and Particle Physics ESFRI research infrastructures) project to create a cluster focused on com- mon issues in data-driven research. Among the ESCAPE work packages, the OSSR (ESCAPE Open-source Scientific Software and Service Repository) is a curated, long- term, open-access repository that makes it possible for scientists to exchange software and services and promote open science. It has been developed on top of a Zenodo com- munity, connected to other services. A Python library, the eOSSR, has been developed to take care of the interactivity between Zenodo, services and OSSR users, allowing an automated handling of the OSSR records. In this work, we present the eOSSR, its main functionalities and how it’s been used in the ESCAPE context to ease the publication of scientific software, analysis, and datasets by researchers
