Introduction

Sensor Metadata API allows you manage metadata associated with sensors. You can add, update or delete custom metadata to sensors. In addition, you can also search for sensors using metadata.

Datatypes

• metadata: A collection of namespaced key-value pairs.
• • namespace: A URL safe string (a-zA-Z0-9_-~)
• • key/value: Any string

e.g: Below is a metadata collection with two namespaces: messages and urls, each with a few key-value pairs.

{
  "messages" : {
    "welcome_title" : "Hello!",
    "welcome_line" : "Welcome to the store!",
    "exit_title" : "Goodbye!",
    "exit_line" : "Please visit us again."
  },
  "urls" : {
    "faq" : "http://www.example.com/faq.html",
    "store" : "http://www.example.com/store.html",
    "support" : "http://www.example.com/support.html",
  }
}
