@odissei.bsky.social "FAIR Vocabularies are really needed in social science research", data managers and researchers agree on this, and @angelicamaineri.bsky.social presented practical work in SSHOC-nl on this direction.

Partners include SURF, @cbsstatistiek.bsky.social, @esciencecenter.bsky.social, @dans-knaw-nwo.bsky.social, @kb.nl, Beeld en Geluid, Centerdata, @meertens-knaw.bsky.social, @iisg-amsterdam.bsky.social, @knaw-nl.bsky.social Humanities Cluster, and many Dutch universities.

🔬 Microscopes revealed cells. 🔭 The Macroscope will reveal societies—how misinformation spreads, how trust evolves, how culture shifts. By 2030, researchers will access secure data vaults, unified archives, transparent AI tools—and new ways to study social change while protecting privacy.

The world’s first Macroscope is coming to the Netherlands 🇳🇱 NWO just awarded €16.8M to build this groundbreaking research infrastructure—co-led by @odissei-soda.bsky.social and CLARIAH, coordinated by @erasmusuniversity.bsky.social #Research #Innovation odissei-data.nl/2025/11/03/t...

For that, we set up consultations and collaborations, organize workshops, write tutorials, and arrange a fellowship program. ✨ If you are a researcher in need of help, or simply want to discuss, we are here for you! Follow us for more updates, and check out our website at odissei-soda.nl ⭐
