Definition of Meta Data and its Usage
Â
Simply we can say that data related to data is Meta data. Specifically, data those carry information about one or more aspects of data can be called Meta data.
Â
For example, time or date created, basic information about a sound file (music) like creator, author, when created, who is the lyricist etc.
Â
For an image, the Meta data (or Meta content) can be of size of picture, depth of color, resolution etc.
