I think we need to start a sub-group, and define a process for filter extensions. Filters are a complex subject, and JMS isn't the only use case they need to support. Even then, a JMS selector needs to have a defined mapping to AMQP concepts. In particular, there's a need for more than one 'dialect', particularly so we can interoperate with OpenMAMA, MQTT, SMTP and, preferably, a native AMQP encoding which allows to access the full fidelity of information present in AMQP structured messages.

The current code 0x0000412B is the IANA code for IIT. But it's important that we have a code assigned from AMQP to ensure that all brokers capable of using NoLocal and JMS filters understand the very same filters. I suggest we use a range from 200 to 255 for filters so the above no-local-filter would have code 0x00000000:0x000000C8 and the jms-selector-filter code 0x00000000:0x000000C9. What do I need to do to get this done? -- Andreas Mueller IIT Software GmbH, Bremen/Germany
