What is the primary purpose of metadata in GIS?

The primary purpose of metadata in GIS is to make an item searchable with a detailed description and relevant tags. Metadata provides critical information about data sets, including their origin, purpose, and content, which enhances discoverability and usability. By including descriptions, keywords, and other details, metadata helps users understand the context, quality, and limitations of the data they are working with. This transparency facilitates data sharing and makes it easier for users to find and utilize the appropriate datasets for their specific needs.

The other options do touch upon aspects of data management within GIS but do not capture the comprehensive role of metadata. For example, while automatically populating fields or ensuring descriptive names can enhance user experience within ArcCatalog, they do not embody the full and essential function of metadata. Similarly, while populating Data Properties with additional information is beneficial, it is not the primary purpose of metadata itself.
