The Linked Data Helper plugin facilitates the creation of data files for use with the Linked Data Vocabularies plugin in Obsidian. It supports the generation of datasets, such as LCSH, and includes a step-by-step guide in the settings for each implemented dataset. The generated files are stored by default in the attachments folder under a subfolder named linked-data-vocabularies. Users can specify an alternative output path if needed. Once the required data files are generated and converted, the plugin can be disabled until an update or additional dataset integration is required.
