The Voyager Space Programme
In 1977 NASA launched 2 Voyager spacecraft
Their mission – to send back scientific information about deep space
Voyager 1 is now farther away from earth than any man-made object has ever been

But…
How would an alien even know what a record was?
How would they even know how to play it?
The answer is METADATA

Why should you create metadata for your work?
Your work will be more readily available because:- It’s easier to find- It’s clear who created it- It’s easy for others to cite in their publications- If everybody creates metadata, you save time and
money too!
It also meets the requirements of some funding bodies to make your work readily available for others.
