Metadata is a set of standardized information about a file, such as author name, resolution, color space, copyright, and keywords applied to it.
File information found in the Document Info panel provides general file information and object characteristics, as well as the number and names of graphic styles, custom colors, gradients, fonts, and placed art.

Working with metadata in Adobe Bridge and Adobe Creative Suite components
You use the Document Info panel to see listings of general file information and object characteristics, as well as the number and names of graphic styles, custom colors, patterns, gradients, fonts, and placed art. To display the panel, choose Window > Document Info.
To view a different type of information, select an option from the panel menu: Document, Objects, Graphic Styles, Brushes, Spot Color Objects, Pattern Objects, Gradient Objects, Fonts, Linked Images, Embedded Images, and Font Details.
To view information on only the selected object, choose Selection Only from the panel menu. Leaving this option deselected lists information about the entire document.
To save a copy of the file information as a text file, choose Save from the panel menu. Specify a name and location, and then click Save.
To view artboard dimensions, click the Artboard tool, choose Document from the panel menu, and then click to select the artboard you want to view.
