Tags are usually considered to be keywords or phrases which help identify the data. They can be anything from posts on social media to documents such as documents or images. These tags serve to identify and categorize items that are related or similar. In addition, particularly within file systems, it helps in the search for certain images, documents, videos, documents, or other media simpler.
The meta information about tags, which can be found in the majority of images, provides information on whether the photo has such tags or not. It does not contain tags by itself. However, it does provide it simply displays a "yes" or "no" to show that tags exist.
Because tags are typically selected by the author or the person who changed files, the tags may differ greatly.
The information in the tagged EXIF differs from the information called the PDF that has been tagged.
