UNIC Templates for uploading corpus metadata v1.11

The UNIC platform (https://unic.dipintra.it) accepts a JSON file for uploading corpus metadata based on the template here. Alternatively, use the spreadsheet template to input the corpus metadata and convert the resulting .xlsm file to JSON using this application at https://huggingface.co/spaces/nannanliu/UNIC_metadata_conversion. When opening the Excel spreadsheet template, please enable Macros, which will automatically validate your input in the columns. Please do not change the order of the columns because they are embedded with code. To add elements and components not included by the UNIC schema, create new columns after the existing ones.
