Entity DataObject

Entity DataObject represents a virtual member manager entity.

All other entity types, like PersonAccount, Group, OrgContainer, are extended from this Entity DataObject. The following shows the inheritance relationship among entity data objects:

• Entity
  • Geographic Location
    • Locality
    • Country

  • RolePlayer
    • Party
      • Person
      • Group
      • OrgContainer
      • LoginAccount
        • PersonAccount

The RolePlayer and Party data objects are for the future expansion of virtual member manager and are part of the schema for this release to provide forward compatibility.

The data graph structure of an entity data object consists of:

identifier

contains a single IdentifierType DataObject.

parent

is a containment property which is used to link to the parent of the entity in the virtual member manager hierarchy. It only contains a single Entity data object because an entity can only have one parent. Also, because any entity can be parent of any other entity, the data object in the property is an Entity data object.

children

is a containment property used to link to the children of the entity in the virtual member manager hierarchy. It contains multiple Entity DataObjects because an entity can have multiple children. Also, because any entity can be a child of another entity, the data object in the property is an Entity data object.

groups

is a containment property which is used to link to the groups this entity belongs to. It contains multiple Group DataObjects because an entity can belong to multiple groups.

XML schema definition

The following is the XML schema definition for Entity DataObject:

<xsd:complexType name="Entity">
<xsd:sequence>
<xsd:element name="identifier" type="IdentifierType" minOccurs="1" maxOccurs="1"/>
<xsd:element maxOccurs="1" minOccurs="0" ref="parent"/>
<xsd:element maxOccurs="unbounded" minOccurs="0" ref="children"/>
<xsd:element maxOccurs="unbounded" minOccurs="0" ref="groups"/>
<xsd:element maxOccurs="1" minOccurs="0" ref="createTimestamp"/>
<xsd:element maxOccurs="1" minOccurs="0" ref="modifyTimestamp"/>
</xsd:sequence>
</xsd:complexType> 

Sample data object

The following is a sample Entity data object that contains one entity as its parent and two Group entities as its groups.

<wim:Root>
<wim:entities xsi:type="wim:PersonAccount">
<wim:identifier uniqueName="uid=persone,ou=OrgUnitA,o=OrgA,cn=users,dc=yourco,dc=com"/>
<wim:groups>  
<wim:identifier uniqueName="cn=Group A,cn=groups,dc=yourco,dc=com"/>
</wim:groups>
<wim:groups>  
<wim:identifier uniqueName="cn=Group B,cn=groups,dc=yourco,dc=com"/>
</wim:groups>
</wim:entities>
</wim:Root>
