In total, the HIKE project has created three different vocabularies, that are interlinked via SKOS principles (https://www.w3.org/TR/skos-reference).

The first scheme contains the national/regional inventory of actual fault objects that form the European FDB, defined by their geographic extent and name the European FDB and delivered by each GSO partner. The description provides additional information to the structured fault data of the FDB and have -in certain instances- been related to similar tectonic boundary objects in adjacent countries. In total, over 2500 fault descriptions from all partner GSOs have been included, making it the largest vocabulary of named fault objects worldwide. Polyhierarchy is possible, i.e., a fault can belong to several broader concepts, and vice versa, a fault system can consists of several narrower concepts. Under the “read more” arrow, technical information in form of all used triples is provided. For detailed explanation, please refer to GeoERA GIP-IP D4.3 and GeoERA GIP-IP D4.4. The paperclip provides links to other online resources, e.g. the same fault represented in other European fault databases, or additional references. A detailed description of the interface elements is available in GeoERA_HIKE_D2.1b, chapter 5.3.

The second vocabulary defines the general terms used in the HIKE project for fault classification and ranking. The different ranking concepts are interchangeable, e.g. a fault domain can be subdivided either into fault sets, fault systems or fault subdomains, depending on the regional/local circumstances. They are also listed in GeoERA_HIKE_D2.1b, chapter 5.2. The third vocabulary part delivers a detailed list of all attribute parameters used in the FDB with all options. Where possible, the parameter lists are semantically related to already existing vocabularies and codelists (e.g, CGI and INSPIRE). For a detailed description and background information, see GeoERA_HIKE_D2.1b, chapter 4.
