Es-Synchronizer contains a set modules able to synchronize resources between two framework. This kind of synchronization is used between [EasierGOV|easiergov:EasierGov - SOA Governance Tool], [EasyESB|easyesb:EASYESB - Open source Lightweight Services Bus]/[PEtALS DSB|petalsdsb:PetalsDSB Overview] and [EasierBSM|easierbsm:EasierBSM - Open source Business Service Monitoring and SLA enforcement].

Es-Synchronizer API provides some ways to synchronize frameworks/platforms together. The initial goal of this API is to be able to get existing resources (i.e. mainly endpoints) and to be notified when resources appears and disappears (with the help of WS Notification implementation). Implementation can be summarized as:

A sample of SOAP notification message emitted by the ESB when a new endpoint is created is:
{code:language=xml}
<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header xmlns:wsa="http://www.w3.org/2005/08/addressing">

<soapenv:Body>

</wsnt:ProducerReference>
<wsnt:Message>
<resourceIdentifier:resourceIdentifier xmlns:resourceIdentifier="http://www.petalslink.com/easyresources/execution-environment-connection-model" xmlns="http://www.petalslink.com/easyresources/execution-environment-connection-model">

</resourceIdentifier:resourceIdentifier>
</wsnt:Message>
</wsnt:NotificationMessage>
</wsnt:Notify>
</soapenv:Body>
</soapenv:Envelope>
{code}

In this snippet, the notification is sent to [http://localhost:9000/services/RawService] and the resource ID is
\{http://www.petalslink.org/endpoint/HelloWorld}HelloWorldServicePort of type _endpoint_.
