A collection of ~2500 geoscientific terms in English (keywords), with unique web addresses (URIs), delivered in RDF format, with translations in different languages, with links to standardized codelists (INSPIRE, GeoSciML, GEMET), thesaurus like modeled in accordance with the search use case and metadata tagging in MICKA. Hosted in an EGDI central repository, online available via web API (Sparql) to drive search systems. Deployed in versioned updates according to a governance workflow.
GeoERA-Keyword-Thesaurus_v1 includes a selection of evaluated and compiled vocabularies, mainly from resources like GEMET, INSPIRE or CGI - see our report

Release notes (20.3.2020):
download latest version of GeoERA Keyword Thesaurus v2.0 at this GitHub page or directly from European Geoscience Registry at https://data.geoscience.earth/ncl/geoera/keyword
1) new URIs according to new EGS domain name:
All keyword concepts have got new identifiers based on the new domain name "data.geoscience.earth" registered by EGS. URI patterns are adapted to the naming conventions of geoscience.earth host. E.g. for the keyword hazard the URI was changed from previous testing environment http://resource.geolba.ac.at/geoera_keyword/hazard to https://data.geoscience.earth/ncl/geoera/keyword/1358. The previous URIs remain in the Keyword Thesaurus to query with property "http://purl.org/dc/terms/replaces". As soon as the Keyword Thesaurus is in the registry all URIs will be resolvable at data.geoscience.earth. Meanwhile and for testing purposes we provide a Sparql endpoint to query the data base (triple store).
2) Fully translated into Slovenian, Spanish and German language:
Initially the Keyword Thesaurus is already available in 4 languages. In some cases, no translation was carried out. Especially for abbreviations in international context.
3) All previous changes included:
The Keyword Thesaurus now contains all modifications as described under v1.1 above.
4) All concepts under a single concept scheme:
Now all concepts are modelled under a single concepts scheme "keyword". Search categories are available as properties (dbPedia/category attributes) of almost each concept. Additionally Search categories have been changed from concept schemes in v1 to top concepts in v2.
5) How to query a list of all keywords: Here an example how to get a table of all GeoERA keywords with URIs and translations into a selected language. Available languages are en, cs, da, el, de, es, et, fi, fr, hr, hu, is, it, lt, nl, no, pl, pt, ro, sk, sl, sv, uk.
The European Geoscience Registry shows the GeoERA Keyword Thesaurus v2 at https://data.geoscience.earth/ncl/geoera/keyword. By clicking around you should be able to navigate to each single keyword. But there is also a link to download a list of all available keywords in different formats. On the upper right you find download links for ttl, rdf/xml or json-ld. If you open the Sparql query form at https://data.geoscience.earth/ncl/ui/sparql-form you can run a query script to show the results in table, txt, json or xml. This code example below would generate a list of all keywords with URI and translations in Finnish (as many as already translated). If you want to fill the column in another language lets say Portuguese just change the filter for “fi” to “pt”.
prefix skos: <http://www.w3.org/2004/02/skos/core#>
select distinct ?uri (str(?k) as ?keyword) (str(?t) as ?translation)
(group_concat(?c;separator="; ") as ?categories)
where {
?uri a skos:Concept; skos:prefLabel ?k
filter(regex(str(?uri), 'ncl/geoera/keyword'))
filter(lang(?k)="en")
optional{?uri skos:prefLabel ?t filter(lang(?t)="fi")}
optional{?uri <http://dbpedia.org/ontology/category> ?c}
}
group by ?uri ?k ?t
order by desc (?t)
Scripts like above also could be (url encoded) embedded into URLs in order to get a file download. This method provides some different useful formats like CSV.
Note: special characters are always coded to utf-8 standard. Do not mistake with ANSI.
