- Matadisco is an open, decentralized network for data discovery built on the AT Protocol, separating data discovery from storage.
- It allows producers to publish metadata records to a Personal Data Server (PDS) with lightweight pointers, supporting standards like STAC and DataCite.
- Consumers can read records via a PDS or Jetstream to build web-based portals for various data types, such as satellite imagery or cultural archives.
- The network uses cryptographically signed records, with no single entity in control, and all components are open-source and self-hostable.
- Prototypes include producers for Sentinel-2 imagery and German geodata, and consumers like real-time viewers and specialized geo-viewers.
- Matadisco is experimental, with future plans to include IIIF for GLAM collections, podcasts, research datasets, and schema evolution based on real-world use.
