Systems

The /systems endpoint provides methods for discovering, creating and interacting with systems. For more on the role that systems play, see:

Systems

All systems provide a base set of metadata that helps to describe their role and capabilities, as well as provide references to the modules they contain, and the zones they exist in.

zones	array	Zone IDs that this system is a member of.
modules	array	Module ID's that this system contains.
description	string	Markdown formatted text that describes the system.
email	string	Calendar email that represents this system. Typically used for room scheduling / bookings.

Operator	Action
+	Matches both terms.
`	`	Matches either terms.
-	Negates a single token.
"	Wraps tokens to form a phrase.
( and )	Provide precedence.
~N	Specifies edit distance (fuzziness) after a word.
~N	Specifies slop amount (deviation) after a phrase.
