OASIS AMQP was approved for release as an ISO and IEC International

The AMQP specification is defined in several layers: (i) a type system, (ii) a symmetric, asynchronous protocol for the transfer of messages from one process to another, (iii) a standard, extensible message format and (iv) a set of standardised but extensible 'messaging capabilities.'

The type-system is used to define a message format allowing standard and extended meta-data to be expressed and understood by processing entities. It is also used to define the communication primitives through which messages are exchanged between such entities, i.e. the AMQP

December 2006, 0-10 published in February 2008 and 0-9-1, published in November 2008. These earlier releases are significantly different from the 1.0 specification.

Properties are specified in the AMQP type system, as are annotations. The application data can be of any form, and in any encoding the application chooses. One option is to use the AMQP type system to send structured, self-describing data.
