Struct Definitions Reference

This page provides a reference for the purpose and structure of all structs standard groups and databases.

Structs groups and databases are marked with a JSON object using the key xs_struct. This will always contain at least two members:

"type" - the name of the type of struct element as a string

"v" - the current version this instance of the specified type as a string

The version allows structs elements to be upgraded as the structs definitions evolve. It uses a basic semantic versioning format, specifically MAJOR.MINOR.PATCH, where:

MAJOR changes indicate breaking structural changes

MINOR changes add functionality in a backward compatible manner

PATCH changes make backward compatible bug fixes

Minor and patch changes will automatically be applied to structs elements in server upgrades, whereas major changes will typically require user interaction. Major changes will be avoided as much as possible to maintain stable workflows.

Events

Event databases come in three forms, simple events, single file per event, and multiple files per event.

Event

Each record is a single event. May be a direct child of either a model or origin:

...<model>.event or ...<origin>.event

type	event
version	1.0.1

Fields

Note that virtual fields are calculated from other fields and cannot be populated manually.

uuid	`uuid`	✓	event UUID
e_id	`int(8)`	✓	event ID (default to `0` if not provided)
t_start	`instant(us)`	✓	start time
t_end	`instant(us)`		end time (if `null`, event is an open interval)
dur	`duration(us)`	✓	virtual duration in microseconds (`null` if open)
interval	`boolean`	✓	virtual `t_start` != `t_end`
open	`boolean`	✓	virtual `t_end` is `null`
type	`struct_event_type`	✓	event type (default to `message` if not provided)
level	`struct_event_level`	✓	event level (default to `none` if not provided)
