Configuring Relationship Types

Configuring the Relationship type involves configuring all the concepts and properties the object can contain, which drive the behavior of the object.

In the Relationship type, the following concepts are available for configuration:

Attributes
Start Object (entity type)
End Object (entity type)

Examples of relation types are:

Parent
Sister
Subsidiary
Division
Affiliated
Contractor

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

Table 1. Relation Type Properties
Property Name	Required	Description	Type
`URI`	Yes	Path that is used to reach this relationship type configuration. The format is:`configuration/relationTypes/{TypeName}`	String, URI
`id`	Yes, for response JSON	Internal, system-generated id that is used internally to get the difference between two versions of configurations when the configuration is updated.	String
`label`	Yes	Readable name of the relationship type.	String
`description`	No	Details, description for the relation type.	String
`extendsTypeURI`	No	URI of relation type is extended by this relation type.	String, URI
`sameAsTypeURIs`	No	Collection URI of the relation type that has the same semantics as this type. In all graphs the configuration of these relation types is used as synonyms; therefore, there is no need to list all possible types in the graph configuration. Example: `"attorney"` and `"lawyer"` relation types.
`reverseOfTypeURIs`	No	Collection of URIs that define the semantic reverse relation type as this type. Example: `"parent"` relation type; reverse is `"child"` relation type. (/To be supported/)
`implicit`	No	If `TRUE`, the relationship is marked as an Implicit relationship. Implicit Relationships that do not appear, for example, in a Network graph because they are deemed not to 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 this between an Individual and an Employer are displayed in a graph. Default is `false`; that is, explicit.	Boolean
`direction`	No	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 the `"parent"` relationship type is used, it is understood that one node is a parent, and 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 must 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`	No	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`	No	Color that is used to visualize this relationship objects of that type (for example, in graph view-color of lines between nodes).	String, hex color
`dataTooltipPattern`	No	Pattern that is used to build entity object tooltip. 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`	No	Attributes that are defined as standard for this entity type. Attributes for relationships can be of simple, atomic type (refer to Attributes configurationfor more details). Note: Not every relation object will have all attributes defined in its relation type. Also, the 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 its type (directional context).
`endObject`	Yes, when inheritance is applied	Defines properties of end object like its type( directional context).
