the laws of the jungle

Weinberger's laws of the jungle
Everything is miscellaneous

The four new strategic principles:
Filter on the way out, not on the way in.
Put each leaf on as many branches as possible.
Everything is metadata and everything can be a label.
In the miscellaneous order, the only distinction between metadata and data is that metadata is what you already know and data is what you're trying to find out.
Give up control.

The "laws of the jungle" chapter (p. 84-106) includes an interesting analysis of the Art & Architecture Thesaurus.
