First draft.

&xep0128; defines a way for an XMPP entity to include extended information in its responses to &xep0030; information requests. This document specifies a usage of XEP-0128 whereby an XMPP entity can provide detailed data about itself in such responses. This protocol is intended to replace &xep0092; for software information discovery (thus reducing or eliminating the need for distinct software version requests) and also provides a format that can be encapsulated into &xep0115; notifications.

To illustrate this usage, consider the following example of a disco#info request-response interaction that includes detailed client information:

]]> urn:xmpp:dataforms:softwareinfo Windows XP Exodus 0.9.1 ]]>

The fields have the following meaning:

os -- The operating system on which the XMPP software is running
os_version -- The operating system version
software -- The XMPP software running at the entity (if this field is provided, its value SHOULD override any software name provided as the value of the 'name' attribute in the service discovery <identity/> element)
software_version -- The XMPP software version

Service discovery information is typically world-readable. Therefore, care should be taken in exposing information that may make it easier for a potential attacker to target the publishing entity's system (e.g., the operating system on which the software is running).

This document requires no interaction with &IANA;.

The ®ISTRAR; shall include the following information in its registries.

&xep0068; defines a process for standardizing the fields used within Data Forms qualified by a particular namespace, and XEP-0128 describes how to use field standardization in the context of service discovery. This section registers fields for software information scoped by the "urn:xmpp:dataforms:softwareinfo" FORM_TYPE.
