Given that Final Cut Pro X is so heavily built on metadata, I thought this article was relevant. Although Godin is talking about the metadata we leave behind as we work or play across the Internet (and our purchase history), it helps with the understanding of what metadata is, in a broader sense.
In any case the conclusion is very relevant:
Data about data is more important than ever, and being on the side of the person creating that data is a smart place to be.
