In the context of ISO datasets, the focus is on metadata standards designed to improve the sharing and accessibility of geospatial data. While the other fields mentioned — Topic Category, Language, and Abstract — are important and contribute to the completeness and usability of the metadata, Resolution is not a required field according to the ISO 19115 standard for geospatial metadata.

The Topic Category helps classify the data into an appropriate category making it easier to retrieve and interpret. The Language field specifies the language of the dataset's metadata, which is crucial for users who need to understand the information presented. The Abstract provides a concise summary of what the dataset entails, allowing users to quickly grasp its contents and relevance.

Resolution, while it might provide valuable information about the detail level of the data, is not mandated, hence its inclusion in the list of options as the field that is not required. This reflects the standard’s focus on ensuring essential information is available for dataset discovery and understanding without making the presence of specific data attributes obligatory.
