Hi All,
I am looking at the integration points for my server now (specifically into the product that my employer develops). It is a workflow solution (www.k2.net <http://www.k2.net>), and I am trying to figure out the best way to notify users that they have work in such as way that:
1. IM clients apart from our own still tell the user that they have work. A Sharepoint web address or such would be given in the body of the message.
2. Our IM client detects that an agent (mobile agent <http://en.wikipedia.org/wiki/Mobile_agent>) is present in the stanza and fires it up instead of giving the user the message.
My thoughts are to simply do the following:
<message from="worklist.k2workflow.com" to="[EMAIL PROTECTED]" type="message">
<body>You have work. Visit http://www.denallix.com/workitem.aspx?uid=12345abc</body>
 <agent xmlns="urn:com:k2:agent"></agent>

</message>
I need to know if any clients would possibly have problems with a stanza in that form, or maybe if someone has a better idea :). Thanks in advance.


That should be just fine.

AND… I also gave some more thought to SOAP and a nice clean <pun> way to implement discovery within a jabber context alone. I thought of using UDDI over XMPP (as it is itself a SOAP standard), this is merely a suggestion, but how about the following:
<iq type='result'

    from='shakespeare.lit'

    to='[EMAIL PROTECTED]/orchard'

    id='info1'>

  <query xmlns='http://jabber.org/protocol/disco#items'>

    <item jid='uddi.shakespeare.lit'

          node='uddi'

          name='SOAP discovery service'/>

    <item jid='[EMAIL PROTECTED]'

                node='urn:myservices:foo'

                name='Some service'/>

  </query>

</iq>
My syntax may all be wrong, but I am sure you get the idea. The client could the start doing UDDI calls against the uddi.shakespeare.lit node. Also (as demonstrated) the server can broadcast any SOAP services it supports upfront.

UDDI? Ick. But if you must, it seems fine to advertise the existence of UDDI services over XMPP -- we could define a new disco identity for that and register it here:


http://www.xmpp.org/registrar/disco-categories.html

I suggest the "directory/uddi" identity.

Once you discover such a service, how would you interact with it? Is that just straight SOAP as in XEP-0072?
