===Declaration Management Services===
The purpose of Declaration Management services, described in chapter 5 of the HLA Interface Specification,<ref name="IFSPEC" /> is to enable federates to declare what information they wish to publish (send) and subscribe to (receive) based on object and interaction classes in the FOM. The RTI uses this information to route updates and interactions to subscribing federates. For an object class, publishing and subscribing are performed for a specific set of attributes. For interaction classes, the entire interaction, including all parameters, is published and subscribed. Key services are:

* PublishObjectClassAttributes that is used to publish a set of attributes for a given object class.
* SubscribeObjectClassAttributes that is used to subscribe to a set of attributes for a given object class.
* PublishInteractionClass that is used to publish an interaction class including all parameters
* SubscribeInteractionClass that is used to subscribe to an interaction class including all parameters
