href="https://web.archive.org/web/20210129000050/http://www.data2dome.org/" target="_blank">www.data2dome.org</a></strong></p> <p><strong>Astronomy is a dynamic discipline, with new press releases, images, videos and data being published every day. Today, however, this flow of exciting new content is typically not integrated in planetariums. Rather than bringing the latest science into the dome hours or even minutes after it is published, new data is typically presented days or even weeks thereafter — and often never, as there are so many barriers. In this way, the planetarium — usually expected to be the local hub of astronomy education — lags behind blogs, newspapers, TV and other media. The Data2Dome (D2D) project aims to streamline content flow from research institutions to planetariums, offering the audience a unique opportunity to access the latest data from space in near real time.</strong></p> <h3 dir="ltr">Vision</h3> <p dir="ltr">The D2D system seamlessly integrates astronomy data into today’s real-time fulldome planetarium systems. Content, and metadata describing this content, is fed via a reasonably fast internet connection (10-20 Mbit/s and up) into the planetarium system in an automated way, significantly reducing the workload for the planetarium operator.</p> <p>Every morning, planetarium presenters around the world will be able to access a menu to select interesting news and fresh datasets — news, sky event data, historical event data and more (see the use cases below) — and mark the full datasets and metadata up for download for possible inclusion in show segments during the day. Some of these items may be under embargo and will only be shown when they are public. In some sense, the presenter becomes an “Astronomical Weatherman”, able to report on fresh events as they take place.<span style="font-size: 14.666666666666666px; font-family: Arial; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline;"><br/></span></p> <p><span><span><img src="https://web.archive.org/web/20210129000050im_/https://docs.google.com/drawings/d/scnwgob84VvImT28HZJRk6Q/image?w=602&h=629&rev=816&ac=1" border="0" width="602" height="629"/></span></span></p> <p>Read the paper here: <a href="https://web.archive.org/web/20210129000050/https://docs.google.com/document/d/1zRw5OjvqPByHac2auNtXIh4zYIW0rFU1vKhsnvTfTDI/edit" target="_blank">https://docs.google.com/document/d/1zRw5OjvqPByHac2auNtXIh4zYIW0rFU1vKhsnvTfTDI/edit#</a></p> <h3>Use Cases under implementation and corresponding JSON feeds</h3> <p>Only a small subset of data types are implemented to start with:</p> <ol> <li>Images (or stills, if you prefer)</li> <li>Videos</li> <li>Events</li> <li>News</li> <li>Audio</li> <li>3D models</li> </ol> <p><span style="color: #000000; font-family: Arial;"><span style="background-color: transparent; vertical-align: baseline; font-size: 14.6667px;"> </span></span></p> <p>(Later, more complicated data types can come.)</p> <p dir="ltr">The following are use cases which are currently being implemented by Content Providers.
