Struct Actions

Struct actions are complex data actions designed to be used with XINA Structs. Unlike most API actions, they may involve complex multi-step operations, and are dependent on the structs configuration of groups and databases.

Data Actions

STRUCT BUFFER IMPORT

Imports a buffer source file into a model.

Property	Value	Req	Default
action	`"struct_buffer_import"`	✓
model	model group specifier	✓
origin	origin name	✓
object_id	object ID of data file	✓
format	`string`	✓
conf	`jsonobject`
strict_units	`boolean`		`false`

If the mn column is an integer it will be interpretted as a literal mnemonic ID. Otherwise the name will be parsed from this format:

<name>[(<unit>[;n0=v0|n1=v1|...])]

<name> will be used for the mnemonic name lookup. The comparison is case insensitive and any whitespace is treated as a single underscore. <unit> is optional. If provided, it must match the unit of an associated mnemonic definition, otherwise an error is thrown. The section after unit defines discrete value mapping.

When a data set is imported the XINA server will run the following steps:

For each row:
- validate time and value
- process mnemonic
  - If mnemonic ID
    - If found in definitions database:
      - If mnemonic is deprecated, throw error
      - Else, use mnemonic for row
    - Else, throw error due to unrecognized ID
  - Else, parse name and optional unit
    - If name match found:
      - If unit is provided and does not match, throw error
      - If mnemonic is deprecated, throw error
      - Else, use mnemonic for row
    - Else, mnemonic is new, create new temporary mnemonic definition based on provided information
If any rows contain same mnemonic and time, throw error
Check for time overlap in database
- If found
  - If on_overlap = fail, throw error
  - Else If on_overlap = delete, delete all data from database in time range of imported data
  - Else (on_overlap = ignore), do nothing
If new mnemonic definitions created, insert into mnemonic definition database
Insert data into mnemonic database

STRUCT MN ALIAS

Adds one or more aliases of name/unit pairs to a single existing mnemonic.

Property	Value
`action`	`"struct_mn_edit"`
`database`	mnemonic definition database specifier
`mn`	mnemonic ID
`aliases`	`string[]`, name/unit pair alias(es) for mnemonic

STRUCT MN EDIT

Edits one or more properties of a single existing mnemonic.

Property	Value	Required
`action`	`"struct_mn_edit"`	✓
`database`	mnemonic definition database specifier	✓
`mn`	mnemonic ID	✓
`name`	`string`, new name/unit pair for mnemonic
`state`	`string`

STRUCT MN MERGE

Merges one or more existing mnemonics into a single existing mnemonic.

STRUCT EVENT

Performs context-aware event operations.

In each of these operations, events may specify a text "name" property. This will be used to lookup a corresponding event ID from the event definitions associated with the database, and create a new definition if one is not found. If a "name" is present, an "e_id" may not also be present, or the action will fail. If the "name" property value is numeric or numeric text, it will interpretted as a direct event ID reference, and will fail if an event definition with the provided ID does not already exist.

STRUCT EVENT INSERT

Inserts one or more events into a single event database.

Property	Value	Req
action	`"struct_event"`	✓
op	`"insert"`	✓
database	event database	✓
object_id	object ID of data file	✓

Any events which specify a name will have the name resolved in the corresponding event definitions database to find the event ID. If none exists, one will be created.

If the event database is configured with an event stream database, the event stream database will be checked for any update or delete change records, and the changes will be applied to the incoming events before they are inserted (with deleted events not being inserted).

If any inserted UEIDs are already present in the database, the action will fail.

STRUCT EVENT OPEN

Creates an open interval event.

Property	Value	Req	Default
action	`"struct_event"`	✓
op	`"open"`	✓
database	event database	✓
archive	archive ID	✓
event	event record	✓
on_duplicate	`"fail"` or `"update"`		`"fail"`

This action is only compatible with event databases configured for event streams.

STRUCT EVENT CLOSE

Closes an open interval event.

Property	Value	Req
action	`"struct_event"`	✓
op	`"close"`	✓
database	event database	✓
object_id	object ID of data file	✓

STRUCT EVENT UPDATE

STRUCT EVENT DELETE

STRUCT EVENT CLEAR

Schema Actions

STRUCT CREATE

The STRUCT CREATE action is used to create a variety of XINA Structs compatible schema elements.

STRUCT CREATE PROJECT

Creates a structs project group.

Property	Value	Req	Default
action	`"struct_create"`	✓
create	`"project"`	✓
parent	group specifier
name	`string`	✓
label	`string`		name
desc	`string`		label

If a parent group is specified, it may not include a structs definition (since project groups must be at the top level of a struct heirarchy). The name (and label, if provided) must not be in use by any group siblings, or the action will fail.

STRUCT CREATE CATEGORY

Creates a structs category group.

Property	Value	Req	Default
action	`"struct_create"`	✓
create	`"category"`	✓
parent	group specifier	✓
name	`string`	✓
label	`string`		name
desc	`string`		label

The parent group must be either a project group or category group, or the action will fail. The name (and label, if provided) must not be in use by any group siblings, or the action will fail.

STRUCT CREATE MODEL

Creates a structs model group.

Property	Value	Req	Default

eventf	`boolean`		`false`
eventfs	`boolean`		`false`
group_teams	team group privilege map
database_teams	team database privilege map

The parent group must be either a project group or category group, or the action will fail. The name (and label, if provided) must not be in use by any group siblings, or the action will fail.

STRUCT CREATE DEF
