I am currently looking at implementing the rules around storing messages described in xep-0160 in openfire.
The second rule states that messages of type 'chat' should be stored unless they only contain chat state notifications, which is fine. But I was wondering whether this could be generalised a bit more to perhaps suggest that any message of type 'chat' with an empty body should not be stored offline. xep-0334 could then be extended to allow a client to hint that a message should be stored offline The reason I suggest this is that there are newer xeps which also contain messages which you wouldn't want stored offline (e.g. xep-0301) and also unknown future ones, but which you also maybe wouldn't want to burden with a <no-storage/> hint. So essentially it makes the rule: 'chat' message stanzas without a <body/> should not be stored offline unless they contain a hint suggesting they should be. Can anyone think of any existing xeps which may be affected by this sort of change (e.g. ones which use a bodiless 'chat' message which would be expected to be stored offline?) -- Ash
