The LUMEN Data Mesh: Connecting Science Across Domains Through Community-owned Data

A climate scientist discovers a sociology dataset that transforms her research. A mathematician finds Earth observation data that validates his model; these scenarios are exactly what the LUMEN Data Mesh is designed to make possible.

Today, scientific data is often locked within disciplinary silos. Communities maintain their own catalogues, standards, and vocabularies, and for good reason: they know their data best. But what if they could make it discoverable by others, without giving up control?

The LUMEN Data Mesh offers a decentralised alternative to traditional centralised platforms. Built around the concepts of data products and data contracts, it lets each scientific community retain full ownership and governance of its data, while making it findable and reusable across domains. This framework will serve as the technological cornerstone of the LUMEN Meta-Search Service.

In this webinar, we’ll walk you through the architecture, show you how it works with a concrete cross-domain scenario, and (most importantly) we want to hear from you: what cross-domain data challenges do you face, and how could a federated approach help?

Format: A 90-minute interactive webinar combining a 30-minute presentation, a 15-minute live walkthrough of a cross-domain scenario, and a 30-minute participatory session powered by Mentimeter. The webinar will be recorded and made available afterwards.

Who is this for? Researchers, data stewards, and infrastructure managers who work across (or want to work across) disciplinary boundaries. Whether you’re in Social Sciences, Mathematics, Earth Systems, or Molecular Dynamics, if you’ve ever wished you could find data beyond your own community’s catalogue, this webinar is for you. No prior knowledge of data mesh concepts needed.
