A tag is a key-value pair assigned to a piece of information or entity (such as devices, data points, alerts, or interventions). This is used as metadata to describe or categorize the item and allows one to find it more readily by filtering or searching. Tags can be used to filter and aggregate an organization’s data along multiple dimensions. They play a fundamental role in slicing and dicing one's data into clearly organized and accessible segments.
- Tags often represent a concept that can grow to take on additional possible values over the lifetime of your application, such as a software_version, customer_id, or robot_id.
- Tags often encode additional metadata about the source of one's measurement as well, as opposed to simply a description.
