Introduction
Finto is a Finnish thesaurus and ontology service that provides a centralized platform for managing and utilizing controlled vocabularies in various applications, including libraries, archives, and research institutions. It enables seamless integration with linked data and supports automated subject indexing through tools like Annif. Maintained by the National Library of Finland, Finto enhances interoperability and accessibility of structured metadata across different domains.
To make a simple search Search Concepts by Query Term we use the following.
library(finto)
concepts <- search_concepts("sibelius")
head(concepts)## # A tibble: 2 × 7
## uri type prefLabel altLabel hiddenLabel lang vocab
## <chr> <chr> <chr> <chr> <lgl> <chr> <chr>
