.. _dds_layers_publication:

Publication
===========

A publication is defined by the association of a :ref:`dds_layers_publication_datawriter` to a :ref:`dds_layers_publication_publisher`.
To start publishing the values of a data instance, the application creates a new DataWriter in a Publisher.
This DataWriter will be bound to the :ref:`dds_layers_topic` that describes the data type that is being transmitted.
Remote subscriptions that match with this Topic will be able to receive the data value updates from the DataWriter.
