A metadata key-value pair to send along with the usage analytics event.
Notes:
- A metadata key must contain only alphanumeric characters and underscores (the Coveo Usage Analytics REST service automatically converts white spaces to underscores and uppercase characters to lowercase characters in key names).
- A metadata value must be a simple string (no other type is allowed).
The
IChangeableAnalyticsMetaObject
interface describes the metadata which can be sent along with any usage analytics event.
