+<h2>Summary</h2>
+<p>
+ This processor consumes messages from AMQP messaging queue and converts them to a FlowFile to be routed to the next component in the flow.
+ At the time of writing this document the supported AMQP protocol version is v0.9.1.
+</p>
+<p>
+ The component is based on <a href="https://www.rabbitmq.com/api-guide.html">RabbitMQ Client API</a>
+ <a href="https://www.rabbitmq.com/getstarted.html">The following guide and tutorial</a> may also help you to brush up on some of the AMQP basics.
+</p>
+<p>
+ This processor does two things. It constructs FlwFile by extracting information from the consumed AMQP message (both body and attributes).
+ Once message is consumed a FlowFile is constructed. The message body is written to a FlowFile and its <i>com.rabbitmq.client.AMQP.BasicProperties</i>
+ are transfered into the FlowFile as attributes. AMQP attribute names are prefixed with <i>amqp$</i> prefix.
+</p>
+<h2>AMQP Properties</h2>
+<p>
+ The following is the list of available standard AMQP properties which may come with the message: <i>("amqp$contentType", "amqp$contentEncoding",
+ "amqp$headers", "amqp$deliveryMode", "amqp$priority", "amqp$correlationId", "amqp$replyTo",
+ "amqp$expiration", "amqp$messageId", "amqp$timestamp", "amqp$type", "amqp$userId", "amqp$appId",
+ "amqp$clusterId")</i>
+</p>
+<h2>Configuration Details</h2>
+<p>
+ At the time of writing this document it only defines the essential configuration properties which are suitable for most cases.
+ Other properties will be defined later as this component progresses.
+ Configuring PublishAMQP:
+</p>
+<ol>
+ <li><b>Queue</b> - [REQUIRED] the name of AMQP queue the messages will retrieved from. Usually provided by administrator (e.g., 'amq.direct')
+ </li>
+ <li><b>Host Name</b> - [REQUIRED] the name of the host where AMQP broker is running.
+ Usually provided by administrator (e.g., 'myhost.com'). Defaults to 'localhost'.
+ </li>
+ <li><b>Port</b> - [REQUIRED] the port number where AMQP broker is running.
+ Usually provided by the administrator (e.g., '2453'). Defaults to '5672'.
+ </li>
+ <li><b>User Name</b> - [REQUIRED] user name to connect to AMQP broker.
+ Usually provided by the administrator (e.g., 'me'). Defaults to 'guest'.
+ </li>
+ <li><b>Password</b> - [REQUIRED] password to use with user name to connect to AMQP broker.
+ Usually provided by the administrator. Defaults to 'guest'.
+ </li>
+ <li><b>Use Certificate Authentication</b> - [OPTIONAL] whether or not to use the SSL certificate common name for authentication rather than user name/password.
+ This can only be used in conjunction with SSL. Defaults to 'false'.
+ </li>
+ <li><b>Virtual Host</b> - [OPTIONAL] Virtual Host name which segregates AMQP system for enhanced security.
+ Please refer to <a href="http://blog.dtzq.com/2012/06/rabbitmq-users-and-virtual-hosts.html">this blog</a> for more details on Virtual Host.

+<h2>Summary</h2>
+<p>
+ This processor publishes the contents of the incoming FlowFile to an AMQP-based messaging system.
+ At the time of writing this document the supported AMQP protocol version is v0.9.1.
+</p>
+<p>
+ The component is based on <a href="https://www.rabbitmq.com/api-guide.html">RabbitMQ Client API</a>
+ <a href="https://www.rabbitmq.com/getstarted.html">The following guide and tutorial</a> may also help you to brush up on some of the AMQP basics.
+</p>
+<p>
+ This processor does two things. It constructs AMQP Message by extracting FlowFile contents (both body and attributes).
+ Once message is constructed it is sent to an AMQP Exchange.
+ AMQP Properties will be extracted from the FlowFile and converted to <i>com.rabbitmq.client.AMQP.BasicProperties</i> to be sent
+ along with the message. Upon success the incoming FlowFile is transfered to <i>success</i> Relationship and upon failure FlowFile is
+ penalized and transfered to the <i>failure</i> Relationship.
+</p>
+<h2>Where did my message go?</h2>
+<p>
+ In a typical AMQP exchange model, the message that is sent to an AMQP Exchange will be routed based on the <i>Routing Key</i>
+ to its final destination in the <i>Queue</i>. It's called <b>Binding</b>. If due to some misconfiguration the binding between the <i>Exchange, Routing Key
+ and the Queue</i> is not set up, the message will have no final destination and will return (i.e., the data will not make it to the queue).
+ If that happens you will see a log in both app-log and bulletin stating to that effect. Fixing the binding (normally done by AMQP administrator)
+ will resolve the issue.
+</p>
+<h2>AMQP Properties</h2>
+<p>
+ Attributes extracted from the FlowFile are considered candidates for AMQP
+ properties if their names are prefixed with <i>amqp$</i> (e.g., amqp$contentType=text/xml). To enrich message with additional AMQP properties
+ you may use <b>UpdateAttribute</b> processor between the source processor and PublishAMQP processor.
+ The following is the list of available standard AMQP properties: <i>("amqp$contentType", "amqp$contentEncoding",
+ "amqp$headers", "amqp$deliveryMode", "amqp$priority", "amqp$correlationId", "amqp$replyTo",
+ "amqp$expiration", "amqp$messageId", "amqp$timestamp", "amqp$type", "amqp$userId", "amqp$appId",
+ "amqp$clusterId")</i>
+</p>
+<h2>Configuration Details</h2>
+<p>
+ At the time of writing this document it only defines the essential configuration properties which are suitable for most cases.
+ Other properties will be defined later as this component progresses.
+ Configuring PublishAMQP:
+</p>
+<ol>
+ <li><b>Exchange Name</b> - [OPTIONAL] the name of AMQP exchange the messages will be sent to. Usually provided by the administrator (e.g., 'amq.direct')
+ It is an optional property. If kept empty the messages will be sent to a default AMQP exchange. More on AMQP Exchanges could be found
+ <a href="https://www.rabbitmq.com/tutorials/amqp-concepts.html">here</a>.
+ </li>
+ <li><b>Routing Key</b> - [REQUIRED] the name of the routing key that will be used by AMQP to route messages from the exchange to destination queue(s).
+ Usually provided by administrator (e.g., 'myKey')
+ In the event when messages are sent to a default exchange this property corresponds to a destination queue name, otherwise a binding from the Exchange to a Queue via
+ Routing Key must be set (usually by the AMQP administrator). More on AMQP Exchanges and Bindings could be found
+ <a href="https://www.rabbitmq.com/tutorials/amqp-concepts.html">here</a>.
+ </li>
+ <li><b>Host Name</b> - [REQUIRED] the name of the host where AMQP broker is running.

+ </li>
+ <li><b>Port</b> - [REQUIRED] the port number where AMQP broker is running.
