Lars Borin developed and delivered the SAOLhist Plus (v1.0) lexicon resource for the spraakbanken/metadata repository, providing comprehensive historical and modern Swedish vocabulary data spanning 1874 to 2015. He curated lemmatized forms and linguistic analyses, embedding rich metadata such as language codes, download URLs, and contributor information. Using YAML for structured metadata management, Lars refined resource statistics, ensured precise date range formatting, and validated integration with downstream NLP workflows. His work emphasized documentation and lexicon curation, updating repository governance artifacts to support reproducibility and discoverability. The project demonstrated careful attention to metadata accuracy and sustainable resource delivery practices.
