## Usage of the term "IoTDB" in projects and product names:

Apache IoTDB, Apache, the Apache feather logo, and the Apache IoTDB project logo are trademarks of The Apache Software Foundation.

Organizations developing products and projects with Apache IoTDB and creating associated marketing materials should adhere to the trademark guidelines for "Apache IoTDB" and its logo. For comprehensive and authoritative guidance on correct trademark usage, please refer to the [ASF Trademarks Guidance](https://www.apache.org/foundation/marks/) and associated [FAQ](https://www.apache.org/foundation/marks/faq/).
It is recommended not to include “IoTDB” in any name to prevent potential trademark issues with the IoTDB project.

To avoid potential trademark issues, it is advised not to include "IoTDB" directly in any product names. For instance, "IoTDB BigDataProduct" is inappropriate because it contains "IoTDB." However, exceptions such as "BigDataProduct, powered by Apache IoTDB" or "BigDataProduct for Apache IoTDB" are acceptable, as they incorporate the full "Apache IoTDB" name. For software identifiers like Maven coordinates or module names, using formats like "iotdb-tool" is permissible. Nominative use of trademarks in descriptions is also allowed, e.g., "BigDataProduct is a submodule for Apache IoTDB".

- School of Software (Tsinghua University), and National Engineering Laboratory for Big Data Software originally launched IoTDB

  - Their team, comprising both graduate students and professional software engineers, actively develops IoTDB.
  - They utilize Apache IoTDB in the metro systems in 3 Chinese cities (e.g. Shanghai Metro), replacing KairosDB.
  - Apache IoTDB stores decade-long data from over 100,000 stations for the China Meteorological Administration (CMA).

- Lenovo developed the TsFile Go version, and uses it in YOFC (Yangtze Optical Fiber and Cable Company). The system collects data from more than 90 thousand data points, stores them to the TsFile (with Go) as the edge storage and then reads them later to send to the cloud.

- Goldwind Science & Technology manages wind turbine data with Apache IoTDB, processing SCADA data from Kafka, storing it in IoTDB, and supporting various queries.

- DaTangXianYi Technology has deployed IoTDB across numerous power stations in China.

- China Tower Corporation Limited uses IoTDB to store the battery data of about 2 million signal towers.

- Beijing Qingzhi IoT Technology uses IoTDB for electric generator's monitoring. Currently they look forward to the cluster mode of IoTDB.

- JianLong Steel is testing IoTDB for using it in their applications.
