Software End User Notes

There is a single XMPP chatroom that has a single user inside the room that is able to talk.  This bot user emits a <message> stanza that contains a special payload that has the raw text included.  Here is an example message stanza:

<message to='enduser@server/laptop' type='groupchat' from='nwws@nwws-oi.weather.gov/nwws-oi'>

<body>KARX issues RR8 valid 2013-05-25T02:20:34Z</body>

<html xmlns='http://jabber.org/protocol/xhtml-im'>

<body xmlns='http://www.w3.org/1999/xhtml'>KARX issues RR8 valid 2013-05-25T02:20:34Z</body>

</html>

<x xmlns='nwws-oi' cccc='KARX' ttaaii='SRUS83' issue='2013-05-25T02:20:34Z' awipsid='RR8ARX' id='10313.6'>

SRUS83 KARX 250220

RR8ARX

:

: AUTOMATED GAUGE DATA COLLECTED FROM IOWA FLOOD CENTER

:

.A CDGI4 20130524 C DH2100/HGIRP 2.63 : MORGAN CREEK NEAR CEDAR RAPIDS

</x>

</message>

So if you are in the chatroom with a client that does not process this special <x> payload, you won’t see all the raw text included in the stanza.  The attributes on the <x> stanza are as follows:

cccc Four character issuing center
ttaaii The six character WMO product ID
issue ISO_8601 datetime in UTC
awipsid The six character AWIPS ID, sometimes called AFOS PIL.
id This is an unique identifier, see below.

The id attribute on the <x> stanza is meant to help clients know if they are missing any products as they parse the stream.  The id contains two values loaded up into one and they are separated by a period. The first number is the UNIX process ID on the system running the ingest process.  The second number is a simple incremented sequence number for the product.

When users join the chatroom, they are given a 60 message history.   These messages may not contain the <x> payload in the situation where the server is restarted.
