I am currently reading through spring integration topics. Came across a notation/prefix --> "int" used in the XML configurations in spring-integration. 

<int:channel id="errorChannel">
<int:queue capacity="500"/>

Can anyone help me in understanding it ? Also somewhere I have seen 'si' being used. What exactly these prefixes specify & are they spring integration specific ? Thanks in advance!

See the top of the file:

xmlns:int="http://www.springframework.org/schema/integration"

The prefix is mapped to an xml namespace (xmlns). Further down...

xsi:schemaLocation="
   http://www.springframework.org/schema/integration  
   http://www.springframework.org/schema/integration/spring-integration.xsd"

The namespace maps to the schema location, which Spring finds in the jar via /META-INF/spring.schemas. The schema defines the elements and what properties they have.

The prefix can be whatever you want, int, si, integration, foo.

It's just a mapping.
