nfdi4cat/voc4cat-tool: Release 0.9.1

A command-line tool written in Python for creating and maintaining SKOS-vocabularies with Excel and GitHub. The voc4cat tool can be run locally but is also well suited for integration in CI-pipelines. It is for example used to maintain the SKOS vocabulary for catalysis voc4cat on GitHub.

Several features are included.

• Conversion between SKOS/turtle representation and Excel/xlsx. The conversion is supported in both directions.
• Checking of vocabularies. This includes formal validation with SHACL-profiles but also additional checks useful for vocabulary maintenance.
• Transforming of vocabularies, which includes switching between different Excel representations or between different RDF representations.
• Documentation generation for publishing the vocabulary for example on GitHub pages.
