===Object Management Services===
The purpose of Object Management services, described in chapter 6 of the HLA Interface Specification,<ref name="IFSPEC" /> is to enable federates to share information about object instances and to exchange interactions.

Object instance names can be reserved or be automatically generated. Federates can register object instances of specified object classes, that are then discovered by subscribing federates. Attributes of these object instances can be updated. These updates will be reflected to subscribing federates. Interactions can be sent. These interactions will be delivered to subscribing federates. Key services are:

Objects:
* ReserveObjectInstanceName that is used to reserve a name to be used for an object instance
* RegisterObjectInstance that is used to register an object instance of a particular object class, either with a reserved name or an automatically generated name.
* DiscoverObjectInstance that is used by the RTI to notify federates subscribing to particular object class that a new object instance has been registered.
* DeleteObjectInstance that is used to delete an object instance
* RemoveObjectInstances that is used by the RTI to notify federates that an object instance has been removed

Attributes:
* UpdateAttributeValues that is used to provide updated attribute values for an object instance
* ReflectAttributeValues that is used by the RTI to notify federates subscribing to particular attributes of updated values.

Interactions:
* SendInteraction that is used to send an interaction of a particular interaction class, including parameter values.
* ReceiveInteraction that is used by the RTI to deliver an interaction, including parameter values, to federates subscribing to a particular interaction class
