The deliverable documents enhancements in semantic search to improve environmental data access, suggesting standards and integration with language models.
This deliverable addresses data discovery challenges in European environmental research infrastructures by documenting semantic search capabilities within ENVRI-Hub NEXT. We assessed existing semantic infrastructures across the ENVRI community, identifying operational SPARQL endpoints in ICOS, Euro-Argo, SeaDataNet, and the NERC Vocabulary Server. Our architecture integrates Semantic Web technologies with Large Language Models through the Model Context Protocol, enabling natural language queries across federated knowledge graphs. We recommend adopting the SKG-IF standard for metadata harmonization and defining a 12-month roadmap with user stories and success criteria. This work aims to democratize environmental data access and advance FAIR principles implementation.
