How should the text value of a new row be formatted when adding metadata items?

When adding metadata items, the text value of a new row must not be empty or include blank spaces because this ensures that the metadata is clear, concise, and properly formatted for processing. An empty value or one filled with blank spaces does not provide any meaningful information and could lead to errors or misinterpretations during data handling.

Moreover, having a non-empty and properly formatted text value is crucial in maintaining data integrity and ensuring that metadata can be easily searched, sorted, and utilized by systems that might rely on that data. This specific requirement helps uphold the standards of data management and enhances the reliability of metadata usage.

In contrast, options suggesting that the value must be empty or could simply contain blank spaces would result in ineffective data handling. Formatting options like requiring all caps do not address the core need for clarity and consistent readability required in metadata items.
