What is the purpose of document properties in a digital document?

The purpose of document properties in a digital document is primarily to provide metadata for identification. These properties serve as essential informational elements that can include the title, author, subject, keywords, creation date, and modification date, among other details. This metadata helps users understand the context of the document, makes it easier to search for and organize files, and supports accessibility features. By including this information, document properties enable efficient management and retrieval of documents.

While enhancing graphical design is important for visual appeal, it does not relate to the core function of document properties. Compliance with security protocols and facilitating direct editing may be relevant to certain aspects of document handling, but they do not encompass the primary purpose of document properties. The key function of these properties is to ensure that documents are easily identifiable and described accurately through the metadata they contain.
