Provide instances in the selected format. Paste text directly or upload files, or both.
CSV and other data files used by bOTTR mappings to generate instances. Only available when using bOTTR format.
Define namespace prefixes to use in your instances and templates. These apply only to the text fields, not to uploaded files which use the prefixes define in each file.
Define custom OTTR templates in addition to the standard core library (see tpl.ottr.xyz). These let you use your own templates in the instances above.
