B2FIND serves as EUDAT’s metadata indexing service, offering a user-friendly discovery portal designed to assist researchers in locating data collections spanning international and interdisciplinary domains. This service is built upon a comprehensive metadata catalog containing research data collections stored across EUDAT data centers and community repositories. By harmonizing metadata descriptions gathered from diverse sources, B2FIND not only ensures consistency in presentation but also facilitates faceted searches that transcend scientific disciplines. It caters to both communities and data providers seeking to publish and enhance the visibility of their metadata, as well as individual researchers looking for data resources across various domains.

  • Repository harvesting through various protocols (e.g., OAI-PMH, CSW, Rest-APIs)
  • Faceted search with 15 facets, including geospatial and temporal search options, supplemented by free text search capabilities
  • Metadata aggregation from community repositories, with support for multiple metadata standards
  • Integration with OpenAIRE Explore
