1. Introduction

This document defines a module for Packet Filtering (XEP-0062) [1] that provides some basic conditions and actions to perform common packet filtering tasks.

This module operates in the "http://jabber.org/protocol/filter/basic" namespace.

2. Conditions

This module defines the fullowing conditions:

Example 1. Matches all presence packets
<presence xmlns='http://jabber.org/protocol/filter/basic'/>
Example 2. Matches all jabber:iq:version IQ packets
<iq xmlns='http://jabber.org/protocol/filter/basic'>jabber:iq:version</iq>
Example 3. Matches all packets from user@company.com
<from xmlns='http://jabber.org/protocol/filter/basic'>user@company.com</from>

3. Actions

This module defines the fullowing actions:

Example 4. Pretend that we don't exist
<bounce xmlns='http://jabber.org/protocol/filter/basic' code='404'/>
Example 5. Send a copy to our home account
<copy xmlns='http://jabber.org/protocol/filter/basic'>me@home.com</copy>

4. Security Considerations

There are no security features or concerns related to this proposal.

5. IANA Considerations

This document requires no interaction with the IANA.

6. JANA Considerations

No namespaces or parameters need to be registered with JANA as a result of this document.
