National Science Foundation Cyberinfrastructure Council's Cyberinfrastructure Vision for 21st Century Discovery document has been released. It is revised from the 2006 draft document but appears to have mostly the same content. I haven't read it yet, but it is beautifully designed with some amazing photographs and visualizations.
This is a very significant document, basically a blueprint for cybersinfrastructure for science over the next five years, with implications beyond this time. From the document, it is focusing on:
...a vision for cyberinfrastructure in four overlapping and complementary areas: 1) High Performance Computing, 2) Data, Data Analysis, and Visualization, 3) Cyber Services and Virtual Organizations, and 4) Learning and Workforce Development.
