architects Irene Cheng and Brett Snyder “have created a virtual map to guide users around Manhattan to sites where projects they describe as ‘visionary’ were planned but never built. The map is available as an interactive iPhone application…that uses GPS technology to detect when a user is near any of the roughly 50 notable sites, triggering a feature that allows the user to learn about the proposal through the architect’s foiled designs and words.

answer Right. And it results in a type of error that doesn't teach you anything. You have chaotic errors where all you can say is, "Boy, this was really screwed up, and I guess I need to go in and go through the whole thing and fix it." You don't have errors that are proportionate to the source of the error. And that means you can never have any sense of gradual evolution or approximate systems. So, the real difference between the current idea of software, which is protocol adherence, and the idea I'm discussing, pattern recognition, has to do with the kinds of errors we're creating. We need a system in which errors are more often proportional to the source of the error.

The International Virtual Observatory Alliance (IVOA) was formed in June 2002 with a mission to "facilitate the international coordination and collaboration necessary for the development and deployment of the tools, systems and organizational structures necessary to enable the international utilization of astronomical archives as an integrated and interoperating virtual observatory." The IVOA now comprises 17 VO projects from Armenia, Australia, Brazil, Canada, China, Europe, France, Germany, Hungary, India, Italy, Japan, Korea, Russia, Spain, the United Kingdom, and the United States. Membership is open to other national and international projects according to the IVOA Guidelines for Participation.

The International Virtual Observatory Alliance (IVOA) organises two Interoperability meeting per year. The second meeting of 2009 is being hosted by the European Organisation for Astronomical Research in the Southern Hemisphere (ESO), and will be held in the main building of the the ESO Headquarters, on November 9-12 in Garching bei München, Germany.

Je vous propose donc une première typologie des «clouds», en quatre familles :
