Relation Types

The Relation Types API is responsible for defining types of relation types (that link entities) that are recognized in a tenant configuration. Examples of relation types are:

Parent
Sister
Subsidiary
Division
Affiliated
Contractor

Structure

A configuration might have a collection of relation types. Each relation type has the following properties:


Property Name	Required	Description	Type
`URI`	Yes	Path that is used to reach this relationship type configuration. It has format:`configuration/relationTypes/{TypeName}`	String, URI
`id`	Yes-for response JSON	Internal, system-generated id. Is used internally to get difference between two versions of configurations when configuration is updated.	String
`label`	Yes	Readable name of the relationship type	String
`description`		Details, description for the relation type.	String
`extendsTypeURI`		URI of relation type is extended by this relation type type	String, URI
`sameAsTypeURIs`		Collection URI of relation type that have the same semantics as this type. In all graphs configuration these relation types will be used as synonyms and there will be no need to list all possible types in graph configuration. Example: "attorney" and "lawyer" relation types.
`reverseOfTypeURIs`		Collection of URIs that define the semantic reverse relation type as this type. Example: "parent" relation type-reverse is "child" relation type.
`implicit`		If `TRUE`, relationship is marked as an Implicit relationship Implicit Relationships that do not appear for example in a Network graph because they are deemed to not be of significant business value in a graphical display. Implicit relationships are used only in Business Objects for reference attributes such as Address, where again its not considered important to render that relationship. Explicit Relationships such as that between an Individual and an Employer are displayed in a graph. Default is `false`- i.e. explicit.	Boolean
`direction`		Identifies directional semantics of relationship object of the type. Supported directions: `directed`- Used when the two nodes that the relationship connects have different business meaning relative to each other. Example: When "parent" relationship type is used, it us understood that one node is a parent the other node is the child. `undirected`- Used when connecting node A to node B, and there is no reverse relationship implied. Example: "professional" might be used to connect a cardiologist to a neurosurgeon). A reverse relationship is neither required nor implied. `bidirectional`- both objects in the relationship are equal and active in a system. Start and end entity types should play the same role. Example: "friendship" relationship in FB (when both sides confirmed that they are friends). Default is directed.	Enum:`directed`, `undirected`, `bidirectional`
`entityEndDateStrategy`		Defines how to handle the relation when the start/end entity is end dated. `END_DATE_RELATION`: End date the whole relation and related crosswalks; `END_DATE_RELATION_CROSSWALKS`: End date related relation crosswalks. Defaults to `END_DATE_RELATION_CROSSWALKS`	Enum: `END_DATE_RELATION`, `END_DATE_RELATION_CROSSWALKS`
`typeColor`		Color that will be used to visualize this relationship objects of that type (for example in graph view-color of lines between nodes)	String, hex color
`labelPattern`		Pattern that is used to build entity object label. Can include static text as well as patterns-attributes in brackets. Note: if the pattern is not specified, then the type's label is used.	String
`attributes`		Attributes that are defined as standard for this entity type. Attributes for relationships can be of simple, atomic type (please find more details in Attributes Configuration page). NOTE: not every relation object will have all attributes defined in its relation type. Also relation object can have some attributes that are not defined in configuration-custom attributes.	JSON object of Attributes Configuration
`startObject`	Yes-when inheritance is applied	Defines properties of start object like it's type, directional context.
`endObject`	Yes-when inheritance is applied	Defines properties of start object like it's type, directional context.

Note: Currently "id" parameters are not supported by Configuration API.

Operations

Get Relation Types Collection

This operation returns an array of Relation Types in configuration for a tenant.
