Thesaurus project

» started in 2011 as LinkedOpenData project» a knowledge representation for geosciences» compensate the temporary discontinuation of

the Austrian Stratigraphic Commission» using semantic web capabilities (RDF/SKOS,

URI‘s) http://resource.geolba.ac.at

» provide codes for attributing data (e.g. for missing INSPIRE codelists)
