The Fourth Network Layer: Data • “We need an end-to-end, layer-by-layer, designed information technology … that are composed of no more than a stack of protocols” • “We need open standards… and above all, we need to teach scientists to work in this new layer of data” 2 From the essay: “I have seen the Paradigm Shift, and It Is Us”, byJohn Wilbanks, in the book “The Fourth Paradigm” Data Web TCP/IP Ethernet

Building the CMG Model and Data Portal • Sparked by Sandy funding (Warner & Ganju) • Goal: A single portal for discovering and viewing distributed data across CMG • Our model output was already available via standard services supported by IOOS • Leverage IOOS-funded portal-building infrastructure • Collaborative between CIDA and IOOS developers (Axiom Data Science) 14
