What's a RDF triple?

Question

In layman\'s terms, what\'s a RDF triple?

Answer 1

Regarding the answer by Adam N. I believe the O.P. asked a previous question regarding data for a social network, so although the answer is excellent, I will just clarify in relation to the "original original" question. (As I feel responsible).

    John | Is a Friend of | James
    James | Is a friend of | Jill
    Jill | Likes | Snowboarding
    Snowboarding | Is a | Sport

Using triples like this you can have a really flexible data structure.

Look at the Friend of a friend (FOAF) perhaps for a better example.
