<section1 topic='Query Actions' anchor='actions'>
<p>The range of actions that might be triggered by interaction with an XMPP entity by means of an XMPP IRI/URI is potentially as wide as the range of extensions to XMPP. This document does not seek to exhaustively define all such potential actions. However, the following actions might be of general interest:</p>

<p>For each such action, the XMPP Registrar maintains a RECOMMENDED "querytype" (this can be thought of as an action name or "verb"; see <cite>RFC 4622</cite> for syntax and semantics) as well as an OPTIONAL list of keys to be used in key-value pairs if appropriate.</p>

<p>The querytypes and key-value pairs related to <cite>RFC 3920</cite> and <cite>RFC 3921</cite> are defined herein; the querytypes and key-value pairs related to protocols defined in the XMPP Standards Foundation's XEP series are defined in the relevant XMPP Extension Protocol specifications.</p>
<section2 topic='Message Action' anchor='actions-message'>
<p>It may desirable for an XMPP IRI/URI to trigger a specialized interface for sending an XMPP message stanza. The RECOMMENDED querytype for this action is "message". If no key-value pair is provided, interacting with an XMPP IRI/URI that contains a querytype of "message" SHOULD trigger an interface that enables the user to input the text of an XMPP message and other relevant parameters (e.g., a message subject or &xep0071; markup).</p>

<p>Completion of some of the actions defined herein will cause changes to an entity's account, subscriptions to information, registration with services, communication with other entities, completion of ad-hoc commands, and the like. Naturally, such changes, information, services, and communications are potentially undesirable (e.g., joining a chatroom whose discussion topic is not of interest to, or even patently offensive to, the joining user). The invoked application SHOULD appropriately warn a human user regarding the potential consequences of the action about to be completed.</p>
