Use a manifest file to upload large batches of files along with their metadata in the Cavatica Uploader. This is similar to the functionality already present in the Command Line Uploader.
Custom metadata fields are visible via the visual interface. You can set the values for these fields from the Files tab of your project or from that individual file's page. Use these custom metadata fields for filtering alongside of preset fields. Note that you cannot create new metadata fields on the visual interface. However, you can create custom metadata fields using the API.
