System and method to create bi-directional event subscriptions

A system to create bi-directional event subscriptions, comprising:

• a first receiver configured to receive a discovery request from a web browser for a URI of a subscription factory of a first topic, and to receive a request from the web browser to create a bidirectional subscription;
• a first transmitter configured to provide a URI of the subscription factory of the first topic;
• a creation module configured to create a first subscription resource to represent an outbound event flow from a first topic to a second topic;
• a second transmitter configured to send a discovery request to a remote host for a URI of a subscription factory of the second topic, and to send a request to the remote host that the remote host create a second subscription resource, to represent an inbound event flow from the second topic to the first topic, wherein the request further comprises a request to entangle the second subscription with the first subscription;
• a second receiver configured to receive from the remote host the URI of the subscription factory of the second topic, and to receive from the remote host a URI of the second subscription resource;
• an entanglement module configured to entangle the first subscription with the second subscription to form the bi-directional event subscription, wherein entangled subscriptions are created in one transaction and deleted in one transaction, such that one subscription of the entangled subscriptions does not exist without the other subscription of the entangled subscriptions,
• wherein the first transmitter is further configured to provide to the web browser a URI of the first subscription.
