An index term (Q12) is a keyword that we use to describe e.g. the topic of a document or the focus area of a project (using main subject (P15)).
Within the scope of Metabase, the label is enough to tag documents; we do not concern ourselves with e.g. expressing the relationships between index terms. Those live in Wikidata, and if necessary, can be queried using federated queries.
That's why the only the only data we provide is:
For example: museum collection (Q18), public art (Q39), authority control (Q17).
SPARQL
Query to find all index terms with their labels and descriptions in Swedish and English:
PREFIX wb: <https://metabase.wikibase.cloud/entity/>
PREFIX wbt: <https://metabase.wikibase.cloud/prop/direct/>
SELECT ?item ?itemLabelEN ?itemLabelSV ?wikidata_iri
WHERE
{
?item wbt:P5 wb:Q12 .
OPTIONAL {?item wbt:P1 ?wikidataQ}
OPTIONAL {?item rdfs:label ?itemLabelEN filter (lang(?itemLabelEN) = "en")}.
OPTIONAL {?item rdfs:label ?itemLabelSV filter (lang(?itemLabelSV) = "sv")}.
BIND(URI(concat("http://www.wikidata.org/entity/", ?wikidataQ)) AS ?wikidata_iri)
}
