Metadata is data about data. More specifically, metadata is a vocabulary that consists of elements or tags that are used to describe a variety of materials including: books, web pages, journal articles, data sets, images, digital exhibitions, and physical objects.

There are multiple types of metadata, including:
1. Descriptive metadata: Used for discovery and identification. This is the most common form of metadata. Almost all metadata you will create will fall into this category.
2. Structural: Describes the physical and/or logical structure of digital resources.*
3. Administrative: Provides information about file type, creation date, and technical information. Most administrative metadata is already imbedded in the file. It is not recommended that you add administrative metadata by hand, unless you have to.
4. Rights: Provides information about who owns the rights (intellectual property) to the resource.
5. Preservation: The information needed to preserve a resource.
Examples of everyday metadata:
- tagging photos in Facebook or Flickr
- naming MS Word files
- giving a title to a Youtube video
- library catalog records
