Detailed explanation-1: -Metadata means “data about data". Metadata is defined as the data providing information about one or more aspects of the data; it is used to summarize basic information about data that can make tracking and working with specific data easier. Some examples include: Means of creation of the data.
Detailed explanation-2: -Metadata is often stored within the digital file itself, or in an accompanying file. For larger volumes of data, a metadata storage system, such as a database, is required. File formats like XML, MPEG4, JPEG2000 are commonly used for metadata storage.
Detailed explanation-3: -What is file metadata? A great way to think of file metadata is as extra information about a file, carried along with that file, that makes it easier to use and find. So it’s not the actual document or photo itself, it’s information about it-like the file’s name, thumbnail image, or creation date.
Detailed explanation-4: -Often used in the context of ongoing research, administrative metadata includes such details as date created, file size and type, and archiving requirements. Descriptive metadata identifies specific characteristics of a piece of data, such as bibliographic data, keywords, song titles, volume numbers, etc.
Detailed explanation-5: -Most media file types can store metadata directly in the file itself. This is typically done in the file header, which is a block of storage that is separate from the actual media payload.
