HTML rendering of IOHN activity 6 ontology
This wiki page provides a human readable rendering of the nomenclature used and defined in the Sand and Erosion management pilot in the IOHN project. The nomenclature is being developed as an OWL ontology, with the namespace http://www.iohn.org/ontology/IOHN-6.
You may download an early snapshot of the nomenclature, in OWL/RDF format, here.
