What are Metadata?

Metadata are data about data

for example lets say we have a hello.txt file which have 1 line of text “Hello World”

In this case “Hello World” are data

Metadata if this data would be:

  • file size
  • file format
  • file created at
  • filename
  • file location
  • created by

Other good example that i heard once:

Telephone connection

Data is the conversation itself, meaning the phone call content

Metadata:

  • when was the connection
  • how long was the connection
  • between which numbers
  • in which country or between which countries
