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 contains three standard parameters:

"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
"conf" - optional JSON object, format depends on type

Versioning is tied to the version number of the XINA server. Typically server updates will automatically apply needed changes to all structs schema elements, incrementing their "v" property to the latest version. In the event an upgrade cannot be performed the version will not be changed.

Groups

Note that group versioning is used to manage databases required within groups.

Project

Top level struct group. All struct groups and databases must be decendants of a project to be recognized. Name and label are customizable.

Created with the STRUCT CREATE PROJECT action.

Struct Parameters

Parameter	Value
type	`"project"`

Group Parameters

Parameter	Value
name	*
label	*

Parameter	Value
type	`"category"`

Model

Group for which all data is locally co-relevant. Must be a child of either a project or category group. Name and label are customizable.

Created with the STRUCT CREATE MODEL action.

Struct Parameters

Parameter	Value
type	`"model"`

Group Parameters

Parameter	Value
name	*
label	*

Pipe

Group for all data from a single pipe. Must be the child of a model group. Name and label are customizable.

Created with the STRUCT CREATE PIPE action.

Struct Parameters

Parameter	Value	Default
type	`"pipe"`

Conf Parameters

Parameter	Value	Default
discrete	boolean	`false`
buffer	boolean	`false`
variable	boolean	`false`
condense	boolean	`false`
duration	archive length in minutes	`60`
partition	`{"from": <y0>, "to": <y1>}`

Group Parameters

Parameter	Value
name	*
label	*

Notes

If discrete is true, mnemonic data is not considered persistent between archives, and open/close interval operations are not supported.

If buffer is true, the mn_buffer database will be generated, and the pipe will be included in automated archive tasks. Otherwise, the STRUCT BUFFER IMPORT action will not be supported.

If variable is true, mnemonic and event databases in the pipe will include the archive ID field (a_id). If buffer is true, variable must be false (since buffer-generated archives cannot be variable).

duration specifies the archive length in minutes, if variable is false. This cannot be changed. The default is 60 minutes (1 hour). A shorter window may be appropriate for very high data volumes. The maximum is 1440 (24 hours), and the value must be evenly divisible into 1440.

Databases

Structs databases typically specify a set of required fields, and may permit the inclusion of additional custom fields. Changes to the spec involving fields will usually be treated as minor version changes, though they may require manual user correction if an added field conflicts with a custom field already present in a particular database instance.

Note that fields marked as virtual are calculated from the values of other field(s) and cannot be populated or edited manually.

All definitions databases must be direct children of a definitions group, and all definitions groups must contain one of each definition database.

Mnemonics

Databases containing mnemonic data. Unless otherwise indicated, mnemonic databases can be configured with a partitioning system which subdivides the tables internally into UTC calendar months. This is beneficial for selective mnemonic data repopulation, since each month can be instantly erased before being regenerated, and doesn't require downtime of the entire dataset. At creation time a start and end year must be specified, and partitions will be created for each month in that range. Data with timestamps outside the range will be stored in either a pre-range or post-range partition as applicable.

Mn Buffer

Each record is a single mnemonic data point. Holds data imported through the buffer pipeline. Unlike other mnemonic databases, may contain duplicate data points.

This database does not hold data indefinitely. The automated archive pipeline will remove data as it is archived and mined into the primary mnemonic databases.

mn_id	`int(4)`	✓	unique mnemonic ID
v	`{conf.type}`		value

Mn Full

Each record is a single mnemonic data point. The data type for mnemonic values is configurable, and determines the database name. By default the mnemonic data group will contain a full float(8) database.

Struct Parameters

Parameter	Value

Spectra

The spectra definition is a property for event databases.

Property	Value	Req	Description
tabs	array of tab conf(s)		custom tabs for UI
presearch	array of presearch confs		custom pre-search components for UI
filters	array of filter confs
grouping	array of field name(s)
charts	charts conf	✓
tables	array of table conf
query	query conf
labels	labels conf

Spectra Tab Conf

Configuration for a spectra search tab. This may be a string, referencing the name of a custom tab implementation, or an object with a "type" property specifying a tab type and additional properties applicable for that type. Currently there are no custom tab types, but they may be added in the future.

Spectra Database Tab

Under Construction

The database tab employs a record search for a separate target database of any type, and a solution for converting a selection from the target database to the spectra database.

Property	Value	Req	Description
type	`"database"`	✓	tab type name
database	database specifier	✓	target database specifier
map	see below	✓	solution to map target selection to spectra selection

The "map" property may be a string, array of strings, or object.

If a string, the value must be the name of a custom selection function (none currently exist, they may be added in the future).

Spectra Presearch Conf

Specifies a set of components to display before the main spectra search component.

Spectra Field Presearch

Specifies a standalone component to search a particular field.

Property	Value	Req	Description
type	`"field"`	✓	presearch type name
field	field specifier	✓
options	see below		options for search dropdown

Spectra Filters Conf

Specifies filters / badges for spectra search.

Property	Value	Req	Description
name	`string`	✓	system name for filter
label	`string`		display label (uses name if absent)
badge	`string`		badge label (uses name if absent)
desc	`string`		description for badge / filter tooltip
color	`string`		color code or CSS class
e	`expression`	✓	expression to apply for filter

Spectra Charts Conf

Specifies options for each spectra chart.

Property	Value	Req	Description
summary	spectra chart conf	✓	summary chart conf
spectra	spectra chart conf	✓	spectra chart conf

Spectra Chart Conf

Specifies options for a single spectra chart.

Property	Value	Req	Description
x	`string[]`	✓	x axis options
y	`string[]`	✓	y axis options
tooltip	`string`		record format string

Spectra Tables Conf
