Basics

The data type of a property is defined when it is created. The data type defines the permitted content of a property. Most data types are used for system properties and certain functions. You can restrict the value set of metadata, e.g. character string, list value, number, etc. or make a property a class or a relationship. For attributes, the data type can also be used to specify whether it is a numerical value (e.g. for priorities) or a free text field (e.g. for complex identities).

Assigning the data type when creating a property.

List of data types

Data type	Feature	Use case	Predefining values necessary?	Example
Relation	Connection between two properties	Assign metadata to an object, map dependencies, assign objects to projects	Yes	e.g. “System role”
Class	determines the classification in the hierarchy and controls the function and assignment of the subordinate values	Mapping the hierarchy levels of product variants	Yes	e.g. list value “T3-B” belongs to the “Product variant” class
List value	Values of a class, configurable as a hierarchy or taxonomy	All metadata that belong to a predefined value lists	Yes	e.g. list value “T3-B” belongs to the “Product variant” class
Array	List of values that are not stored as properties in plusmeta	Particularly suitable for metadata that is often multi-valued, e.g. lists or imported metadata values	No	e.g. “Tools”, “List of materials”, etc.
Object relation	Relation between a property and an object	Yes	e.g. “uses configuration”, “has assigned AI model”
Project relation	Assigns objects to projects	Yes	e.g. “created by project”
Text (lang)	Maximum length configurable	Continuous text (comment fields, etc.)	No	e.g. “Comment”
Boolean value	True / False	Binary metadata or attributes	Yes	e.g. metadata attribute “Mandatory”
Number	Maximum length configurable, only numeric values	Particularly suitable for pure numerical values that are single-valued	No	e.g. “serial number”, “order number”, etc.
String value	Free text, maximum length configurable	Particularly suitable for metadata that is single-value	No	e.g. “Serial numbers”, “ID”, etc.
Timestamp	Date and time information	all dates	No	e.g. “Creation date”, “Order date”, etc.
