Currently this API is the extract structured box metadata which uses a template to extract data. There is also https://developer.box.com/reference/post-ai-extract/ which uses a list of fields to extract metadata. An additional processor can be created if needed and the name of the processor can be turned into something like `ExtractStructuredBoxFileMetadata` and `ExtractFreeformBoxFileMetadata` -- This is an automated message from the Apache Git Service.
