Have you already tried the SPARQL search functionality?
The European Data Portal currently offers over 750,000 datasets, and these datasets can be accessed in different ways. One can browse per catalogue, per category, and one can search for keywords. Another, more sophisticated option is the use of the SPARQL search function. SPARQL stands for SPARQL Protocol and RDF Query Language, and enables users to query information from databases or any data source that can be mapped to RDF.
The SPARQL standard is designed and endorsed by the W3C and helps users and developers focus on what they would like to know instead of how a database is organised. SPARQL is designed to enable Linked Data for the Semantic Web. Its goal is to assist people to enrich their data by linking it to other global semantic resources, thus sharing, merging, and reusing data in a more meaningful way.
