Collections allow you to group together related items that have been uploaded into Audio-Video. Audio files, videos, photographs, texts, and visualizations (such as charts or maps) can be included together in a collection. Collections can also contain member groups with different permissions.
If you have large topics within a collection, you can create sub collections. For example, you have an "Architecture of Ukraine" collection, you can create subcollections devoted to Churches, public buildings, etc.
