How does metadata enhance the usability of datasets?

Metadata enhances the usability of datasets by providing essential details about other data. This context can include information such as the source of the data, its structure, relevant dates, and how it was collected or generated. With this information, users can understand the dataset better, leading to more effective analysis and decision-making.

Metadata acts as a guide, allowing users to evaluate the quality and relevance of the data, determine its applicability for their specific needs, and facilitate easier integration with other datasets. Without sufficient metadata, users may struggle to interpret the information correctly, leading to potential errors or misapplications.

The other options do not align with the primary function of metadata. For instance, obscuring the context of the data would hinder usability rather than enhance it. Similarly, limiting access to specific user groups does not support the general usability of the dataset for a broader audience. Preventing changes to the data also relates to data integrity and security rather than enhancing usability, as it does not contribute additional context or understanding of the data itself.
