===Online collaborative sensor data management platforms===
Online collaborative sensor data management platforms are on-line database services that allow sensor owners to register and connect their devices to feed data into an online database for storage and also allow developers to connect to the database and build their own applications based on that data. Examples include [[Xively]] and the [http://wikisensing.org Wikisensing platform] {{Webarchive|url=https://web.archive.org/web/20210609165209/http://wikisensing.org/ |date=2021-06-09 }}. Such platforms simplify online collaboration between users over diverse data sets ranging from energy and environment data to that collected from transport services. Other services include allowing developers to embed real-time graphs & widgets in websites; analyse and process historical data pulled from the data feeds; send real-time alerts from any datastream to control scripts, devices and environments.
