Client applications can publish data as well as subscribing to it.
Your application can send data to Liberator for onward transmission. Typically, the Liberator would pass the data on to a suitable Transformer or Integration Adapter to be handled in a custom way. The published data could ultimately be sent to other client applications that have subscribed to it, or it could be sent to other external systems via Integration Adapters.
This technique is used in client trading applications (such as Caplin Trader applications) to send trade messages from the client to a trading system, via Liberator and a Trading Adapter.
