LusTRE is characterised by three main components:
Vocabulariesnavigation tab, consists in a compilation of various environmental vocabularies and in the matching between the concepts addressed by them. In such way it is possible to navigate the vocabularies as one virtual integrated linked data source. The knowledge infrastructure includes vocabularies related to different INSPIRE data themes: multi-purpose environment thesauri as well as vocabularies for Biodiversity, Habitat, Biotopes, Species Distribution, Biogeographical Region, Protected Site, Geology, Air Quality etc. Moreover, their concepts are linked with the concepts of other vocabularies exposed in the LOD cloud.
Servicestab, a set of Thesaurus Framework Exploitation Services that allows to make optimum use of the knowledge contained in the knowledge infrastructure for improving existing metadata tools and geoportals. Different tools such as metadata editors, metadata validators, CSWs, information portals or specific application solutions, can use the services. Some use cases:
Explorationtab, which provides a human-accessible interface to search and browse the concepts of the knowledge infrastructure LusTRE-VOC exploiting the LusTRE-ES services. One specific subcomponent of LusTRE-WEBe is a tool for visual browsing LusTRE-WEBe-Vis, that allows the semantic explorative search among interlinked thesauri.
The database can also be explored using this AJAX-based SPARQL Explorer.
