Abstract
The basic concepts underlying our analysis of W-algebras as extended symmetries of integrable systems are summarized. The construction starts from the second hamiltonian structure of ``Generalized Drinfel'd-Sokolov'' hierarchies, and its correspondence with the A1-embeddings is established, providing a rather simple and general scheme.
