What does metadata refer to?

Metadata refers to the information that provides context about other data. It serves as data about data, describing various attributes such as the source, creation date, format, and the content of the actual data. This contextual information is crucial for understanding how to interpret and utilize the data effectively. For example, in a dataset, metadata can explain what each column represents, the units of measurement used, or the methodology for data collection. Without metadata, raw data may be challenging to understand or could lead to misinterpretation, as users would lack insights into what the data signifies. This foundational aspect of metadata allows for better data management, sharing, and analysis, reinforcing its critical role in data operations and practices.
