ICOS open SPARQL endpoint GUI (for humans)

ICOS has developed its own metadata model and ontology to describe all the digital objects it manages, and the relationships between them – not only data but also people, measurement stations, instruments, etc. This user interface to the open SPARQL endpoint gives advanced human users access to our complete ontology based ICOS metadata repository. In order to give users a head start, a set of common queries are provided in the GUI itself. In addition, for each search made using our data discovery and access portal (https://data.icos-cp.eu/portal/), the equivalent SPARQL query is available; these can be entered into the GUI or saved allowing to reproduce the search at a later time. The GUI supports export of the SPARQL query results in several formats, including JSON, CSV, XML and TSV/Turtle. Note that some familiarity with SPARQL (SPARQL Protocol and RDF Query Language), LOD (Linked Open Data) and OWL (the Web Ontology Language) is strongly recommended for users who want to create their own queries in the GUI.
