Most of the time, the data itself is not enough and additional information about the data is needed. This "data about the data" is known as metadata and even though the Greek prefix means "after", it usually comes at the very beginning of the file. Most file types require metadata and have a strict set of rules of where it is located and how long it needs to be. Some of this metadata could include title, author, keywords, date created, location it was created, file size, height, width, and many more. Examples of what this metadata might look like will be discussed later in this chapter.
