The above links, however, describe some exceptions, like for names such as “BigDataProduct, powered by Apache IoTDB” or “BigDataProduct for Apache IoTDB”. In summary, any names contain &quot;Apache IoTDB&quot; as a whole are acceptable.<br> A common practice you can take is to create software identifiers (Maven coordinates, module names, etc.) like “iotdb-tool”. These are permitted. Nominative use of trademarks in descriptions is also allowed, as in “BigDataProduct is a subproduct for Apache IoTDB”.</p><h3 id="companies-and-organizations" tabindex="-1"><a class="header-anchor" href="#companies-and-organizations"><span>Companies and Organizations</span></a></h3><p>To add yourself to the list, please email <a href="mailto:dev@iotdb.apache.org">dev@iotdb.apache.org</a> with your organization name, URL, a list of IoTDB components you are using, and a short description of your use case.</p><p>You can also leave the info on <a href="https://github.com/apache/iotdb/discussions/4040" target="_blank" rel="noopener noreferrer">Github<span><svg class="external-link-icon" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" focusable="false" x="0px" y="0px" viewBox="0 0 100 100" width="15" height="15"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path><polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg><span class="external-link-icon-sr-only">open in new window</span></span></a>.</p><ul><li><p>School of Software (Tsinghua University), and National Engineering Laboratery for Big Data Software that initially launched IoTDB</p><ul><li>We have both graduate students and a team of professional software engineers working on the stack</li><li>We use Apache IoTDB in Shanghai Metro and two other cities in China to replace KairosDB.</li><li>We use Apache IoTDB in CMA (China Meteorological Administration) for storing 10-years station data.
