We’re quite sure you have heard this one before – Metadata!
Metadata is data about the data or additional information about the information.
I remember when I heard Metadata first time, it sounded gibberish. Data about the data! Let us take an example to clarify it more. When you create a word file on your pc or desktop and if you hit the ‘Save As’ option, on that moment some data is created with the document automatically. File name, size of the file, and the author’s name is created that time and you don’t have to do a bit to create this information. If we take another example of a book, attributes of a book like – the title, author name, date of publication, subject, and ISBN number are used for searching.
