<p>This JEP defines methods for exchanging instant messages that contain lightweight text markup. In the context of this JEP, "lightweight text markup" is to be understood as a combination of minimal structural elements and presentational styles that can easily be rendered on a wide variety of devices without requiring a full rich-text rendering engine such as a web browser. Examples of lightweight text markup include basic text blocks (e.g., paragraphs), lists, hyperlinks, image references, and font styles (e.g., sizes and colors).</p>

|

<p>In the past, there have existed several incompatible methods within the Jabber community for exchanging instant messages that contain lightweight text markup. The most notable such methods have included derivatives of &w3xhtml; as well as of &rtf;.</p>
|
||||
<p>Although it is sometimes easier for client developers to implement RTF support (this is especially true on certain Microsoft Windows operating systems), there are several reasons (consistent with the &jep0134;) for the &JSF; to avoid the use of RTF in developing a protocol for lightweight text markup.

Specifically:</p>

<ol type='1' start='1'>
|

<li>RTF is not a structured vocabulary derived from SGML (as is &w3html;) or, more relevantly, from XML (as is XHTML 1.0).</li>
|
||||
<li>RTF is under the control of the Microsoft Corporation and thus is not an open standard maintained by a recognized standards development organization; therefore the JSF is unable to contribute to or influence its development if necessary, and any protocol the JSF developed using RTF would introduce unwanted dependencies.</li>

<li>XHTML is a structured format that is defined as an application of &w3xml;, making it especially appropriate for sending over Jabber/XMPP, which is at root a technology for streaming XML (see &xmppcore;).</li>

<section1 topic='Requirements' anchor='reqs'>
|

<p>HTML was originally designed for authoring and presenting stuctured documents on the World Wide Web, and was subsequently extended to handle more advanced functionality such as image maps and interactive forms. However, the requirements for publishing documents (or developing transactional websites) for presentation by dedicated XHTML clients on traditional computers or small-screen devices are fundamentally different from the requirements for lightweight text markup of instant messages; for this reason, only a reduced set of XHTML features is needed for XHTML-IM. In particular:</p>

|

<li><p>IM clients are not XHTML clients: their primary purpose is not to read pre-existing XHTML documents, but to read <em>and generate</em> relatively large numbers of fairly small instant messages.</p></li>
|
||||
<li><p>The underlying context for XHTML content in Jabber/XMPP instant messaging is provided not by a full XHTML document, but by an XML stream, and specifically by a message stanza within that stream. Thus the <head/> element and all its children are unnecessary. Only the <body/> element and some of its children are appropriate for use in instant messaging.</p></li>
|
||||
<li><p>The XHTML content that is read by one's IM client is normally generated on the fly by one's conversation partner (or, to be precise, by his or her IM client). Thus there is an inherent limit to the sophistication of the XHTML markup involved. Even in normal XHTML documents, fairly basic structural and rendering elements such as definition lists, abbreviations, addresses, and computer input handling (e.g., <kbd/> and <var/>) are relatively rare. There is little or no foreseeable need for such elements within the context of instant messaging.</p></li>
|
||||
<li><p>The foregoing is doubly true of more advanced markup such as tables, frames, and forms (however, there exists an XMPP extension that provides an instant messaging equivalent of the latter, as defined in &jep0004;).</p></li>

<section1 topic="Architectural Assumptions" anchor='arch'>
|
||||
<p>The usual architecture of XMPP is described in Section 2 of <cite>RFC 3920</cite>. In essence, XMPP is most commonly deployed using a client-server (or logical peer-to-peer) architecture quite similar to that of the email system, except that XMPP does not have multiple hops between servers, enforces domain names to prevent address spoofing, and enables channel encryption (via TLS) and authentication (via SASL) between client and server as well as among servers.</p>
|
||||
<p>The binding of SOAP to XMPP assumes that most SOAP-enabled XMPP entities will be implemented as XMPP clients that communicate with other entities as logical peers. However, in order to deploy more scalable services, such entities could also be implemented as server-side components (see &jep0114;) or even as special-purpose XMPP servers.</p>
|
||||
<p>The SOAP specification defines the concepts of "SOAP intermediary" and "ultimate SOAP receiver" (see Section 1.5.3 of <cite>SOAP Version 1.2 Part 1</cite>). In general, this specification assumes that XMPP entities that support the SOAP XMPP Binding will be ultimate SOAP receivers, since SOAP intermediaries tend to be artifacts of the existing SOAP bindings (HTTP and SMTP) rather than applicable to all possible bindings. SOAP intermediaries are usually deployed in order to (1) cross trust boundaries in protocols that do not enforce domain names or authenticate end-points, (2) ensure scalability, (3) secure messages sent over unencrypted channels, and (4) provide message tracing. However, these issues are addressed natively in XMPP (e.g., channel encryption is defined in <cite>RFC 3920</cite>), in XMPP extensions (e.g., message tracing is defined in &jep0079;), or in deployment decisions such as business level agreements between XMPP domains. One final justification for SOAP intermediaries is to act as gateways between different transport mechanisms (e.g., between HTTP and SMTP), and XMPP entities may well be SOAP intermediaries for that reason. For further details about gateways between XMPP and other SOAP bindings, refer to the <link url='#impl'>Implementation Notes</link> section of this document.</p>

<section1 topic='Requirements and Approach' anchor='reqs'>
|
||||
<p>Defining a protocol suite provides a high-level "bucket" into which we can place specific functionality areas for development and compliance testing. A baseline is provided by RFCs 3920 and 3921, which define XML streams, JID processing, channel encryption, authentication, the three primary XML stanza types (&MESSAGE;, &PRESENCE;, and &IQ;), namespace handling, presence subscriptions, roster management, and privacy lists (whitelisting/blacklisting). However, basic Jabber instant messaging and presence applications should support several additional protocols that were not included in the XMPP specifications for either of the following reasons:</p>

<section1 topic='Definition' anchor='def'>
|
||||
<p>The software developed in the Jabber community is built on the foundation of XML streams, a consistent addressing scheme (JIDs), channel encryption, authentication of an entity (client or server) with a server, three core data elements (&MESSAGE;, &PRESENCE;, and &IQ;), and proper handling of XML namespaces. These foundational building blocks have been formalized within RFC 3920, support for which is REQUIRED by this protocol suite. However, XMPP Core is not fully congruent with the core of what has traditionally been known as "Jabber", and this divergence needs to be captured in the Basic IM Protocol Suite. In particular, the following are REQUIRED herein in order to ensure compatibility with the large deployed base of older Jabber software:
|
||||
<note>Older software also used port 5223 for SSL-enabled communications between a client and a server, rather than upgrading port 5222 as is done during TLS negotiation (the equivalent for server-to-server communications was never implemented); while support for this behavior is OPTIONAL, it may be quite desirable in order to interoperate with older software and deployments.</note>
|
||||
</p>
|
||||
<ul>

||||
<li>Support for &jep0078; as a fallback method for authentication.</li>
|
||||
<li>Support for the error 'code' attribute specified in &jep0086;.</li>
|
||||
<li>Support for &xep0078; as a fallback method for authentication.</li>
|
||||
<li>Support for the error 'code' attribute specified in &xep0086;.</li>
|
||||
</ul>
|
||||
<p>RFC 3920 does not define everything that is normally expected of even a minimal instant messaging and presence application (in effect, it defines the transport layer rather than the IM and presence application layer). Much of this IM and presence functionality is defined in RFC 3921 in order to meet the requirements of RFC 2779. In particular, RFC 3921 defines roster management, presence subscriptions, privacy lists (whitelisting/blacklisting), and routing and delivery guidelines for clients and servers.</p>
|
||||
<p>However, Jabber instant messaging and presence applications have traditionally also included the ability to discover information about other entities on the network, and to reply to queries for information. This behavior is extremely helpful because it ensures that entities on the network can determine each other's capabilities and thus understand how to communicate together. (The original such protocol was &jep0094;, but that protocol has been superseded by &jep0030;.) Support for Service Discovery is therefore REQUIRED by this protocol suite, as well.</p>

<p>Traditionally, Jabber servers (and some services) have also offered the ability for clients to register accounts "in-band" (i.e., over Jabber/XMPP) in order to bootstrap participation on the network; this protocol is defined in &jep0077; and support for it is REQUIRED for servers but RECOMMENDED for clients (however, any given server deployment MAY disable in-band registration as a matter of service provisioning).</p>
|
||||
<p>However, Jabber instant messaging and presence applications have traditionally also included the ability to discover information about other entities on the network, and to reply to queries for information. This behavior is extremely helpful because it ensures that entities on the network can determine each other's capabilities and thus understand how to communicate together. (The original such protocol was &xep0094;, but that protocol has been superseded by &xep0030;.) Support for Service Discovery is therefore REQUIRED by this protocol suite, as well.</p>

<p>The oper attribute is application-specific and refers to the operation for which a permission check is required (e.g., read/write operations).

<p>The 'jabber:iq:auth' method specified herein has been deprecated. However, because it will take some time for existing implementations and deployments to be upgraded to SASL, client and server software implementations still need to include support for 'jabber:iq:auth' in order to interoperate, and this document provides canonical documentation of the 'jabber:iq:auth' method. Nevertheless, implementation and deployment of SASL authentication is strongly recommended, since the 'jabber:iq:auth' method will eventually be obsoleted entirely.</p>
