<p>The process for submitting a proposal for consideration as a XEP is straightforward:</p>
|
||||
<ol>
|
||||
<li>Contact the &EDITOR; so that he knows to expect your submission.</li>
|
||||
<li>Write your proposal following the guidelines described in this document.</li>
|
||||
<li>Make sure that you read, understand, and agree to the &XSFIPR; before you submit your proposal.</li>
|
||||
<li>Send your XML file (or a URL pointing to the file) to the XMPP Extensions Editor.</li>
|
||||
<li>Send your XML file (or a URL pointing to the file) to the &EDITOR; team via email to editor@xmpp.org (make sure that the email subject includes the string "XEP" somewhere in it!)..</li>

|
||||
<p>The XMPP Extensions Editor team prefers that you work as follows:</p>
|
||||
<ol>
|
||||
<li>Check out a copy of the XSF's git repository by following the instructions at &SOURCECONTROL;</li>
|
||||
<li>Make your desired changes to the document, including an updated <revision/> element as described below.</li>
|
||||
<li>Generate a patch using the command <strong>git format-patch HEAD^</strong></li>
|
||||
<li>Send the patch using the command <strong>git send-email --to=editor@xmpp.org NAMEOF.patch</strong></li>
|
||||
<li>Create your own fork of the XSF's git repository (the address of the GitHub mirror can be found at &SOURCECONTROL;).</li>
|
||||
<li>Create a dedicated branch for these changes in your forked repository.</li>
|

<li>Make your desired changes to the document or documents, including an updated <revision/> element as described below.</li>
|

<li>Commit and push the changes to your branch.</li>
|

<li>Create a pull request from your fork to the master branch at the GitHub mirror.</li>
|

</ol>
|

<p>The XMPP Extensions Editor will then apply your patch and publish an updated version of your XEP.</p>
|
||||
<p>The XMPP Extensions Editor team will then process your pull request, seek Council approval if necessary, and publish an updated version of your XEP.</p>
|
||||
<p>NOTE: As explained in <cite>XEP-0001</cite>, updated versions of XEPs in the Experimental state are published without the need for approval by the XMPP Council. However, updated versions of XEPs in the Active, Draft, or Final state must be approved by the XMPP Council to ensure proper change control regarding approved protocols.</p>

<section2 topic='Working with XEP Files' anchor='format-work'>
|
||||
<p>The best way to start working on your proposal is to retrieve all of the existing XEP files and associated stylesheets from source control. These files are stored using the git system as described at &SOURCECONTROL;. The document structure is formally defined by both a DTD and an XML schema, but you do not need to understand the formal descriptions in order to author a XEP. In addition, a handy template file is included as the 'xep-template.xml' file in the 'extensions' directory, providing a quick starting point for XEP authoring.</p>
|
||||
<p>To create your proposal, do a git clone of the 'xeps' repository, go to the 'xeps/' directory you just cloned (e.g., 'cd xeps'), copy the template file (e.g., 'cp xep-template.xml xep-foo.xml'), and start editing the file using either a basic text editor or a specialized XML editing application such as XML Spy or XMLmind.</p>
|
||||
<p>Even if you use a basic text editor, you should be able to view your document in most modern web browsers as an XML file as long as you have xep.xsl and xep.dtd in the 'xeps' directory. Because of inconsistencies in browser XSLT implementations, certain formatting (e.g., table layouts and the numbering of tables, examples, and footnotes) might not be perfect. Don't panic; it will look fine in the HTML output produced by the XMPP Extensions Editor. If your XML file doesn't render at all (i.e., it's just one big text blob), you are using a bad browser. If you see only the bare outline generated by xep.xsl but none of your text, you have an error in your XML. You can check your XML syntax at xml.com <note><<link url="http://www.xml.com/pub/a/tools/ruwf/check.html">http://www.xml.com/pub/a/tools/ruwf/check.html</link>></note>.</p>
|
||||
<p>To programatically convert your XML file into HTML, we recommend using Daniel Veillard's <link url='http://xmlsoft.org/XSLT/'>xsltproc</link> program, which will give you helpful error messages regarding XML syntax problems. However, the XMPP Extensions Editor will complete the final rendering of XML into HTML as well as posting of your HTML file to www.xmpp.org, so you do not need to generate HTML files for submission to the XMPP Extensions Editor (in fact, the XMPP Extensions Editor requires that you submit your proposal in the XEP XML format, not HTML).</p>
|
||||
<p>Finally, the xep.ent file contains convenient "external entities" that provide shortcuts for including references to XMPP Extension Protocols, RFCs, and other common strings. Unfortunately, most browsers do not correctly process external entities, so you cannot include entities from xep.ent if you need to view your XML source file in a browser. However, the XMPP Extensions Editor reserves the right to convert your markup to external entities, since it makes his life easier. Also, please do not add items to the xep.ent file; instead, add them as inline entities within your document and then ask the XMPP Extensions Editor to add them to the xep.ent file.</p>

<section2 topic='File Metadata' anchor='format-metadata'>
|

<p>This section describes the metadata elements contained in the <header/> element of a XEP file (see below for the file contents).</p>
|
||||
<p>The XML character data of the <title/> element is the title of your XEP. Choose a descriptive title that is less than ten words long. The XMPP Extensions Editor may change this in consultation with the author.</p>
|
||||
<p>The XML character data of the <abstract/> element SHOULD be one or two sentences that capture the essence of your proposal (usually beginning "This specification defines an XMPP protocol extension that..."). The XMPP Extensions Editor has been known to modify the abstract so that it accurately describes the proposal.</p>

|

<p>The XML character data of the <legal/> element MUST be as defined in the XSF IPR Policy and reflected in both the xep.ent file and the XEP template.</p>

<p>The XML character data of the <number/> element SHOULD be "xxxx"; this will be changed to the next sequential XEP number by the XMPP Extensions Editor if the XMPP Council accepts the proposal as an XMPP Extension Protocol.</p>

|
||||
<p>The XML character data of the <type/> element SHOULD be either "Standards Track" or "Informational" (there are also Historical, Humorous, and Procedural XEPs, but these are uncommon and usually written by the XMPP Extensions Editor). A Standards Track XEP defines an XMPP extension intended to be used as a common part of XMPP technologies. An Informational XEP defines best practices or a usage profile related to XMPP or an XMPP Extension Protocol (e.g., &xep0175;).</p>

<p>The XML character data of the <approver/> element SHOULD be "Council".</p>

<p>Include one <revision/> element for each revision of your document. The XML character data of the <version/> element SHOULD be "0.0.1" for your initial submission to the XMPP Extensions Editor, and the <remark/> SHOULD be "First draft."; for each revision, you will include another <revision/> element (place it <em>before</em> the existing <revision/> elements) and iterate the <version/> element (e.g., "0.0.2" after "0.0.1" or "0.10" after "0.9").

<section2 topic='File Contents' anchor='format-contents'>
|

<p>Aside from the metadata in the <header/> element (see above), a XEP file is a series of sections, arranged in a hierarchy (<section1/> is a top-level section, within which you can nest <section2/> sections, and so on down to <section4/>). The title of a section is captured in the 'topic' attribute. You should also include an 'anchor' attribute so that you can link to page fragments from within your document. The allowable elements within a section element probably look familiar from XHTML: <p/> for paragraphs, <ol/> and <ul/> for ordered and unordered lists, and so on.</p>
|

@ -141,12 +147,12 @@
|
||||
<p>The <p/> and <li/> elements can also contain more markup that is familiar from XHTML, such as the <img/> element. Note that hyperlinks are of the form <link url='foo'>bar</link> rather than <a href='foo'>bar</a> (the reasons for this are lost in the mists of time and it is too late to change it now, so you'll just have to adjust). If needed, you can also use inline structural and presentational markup such as <em/>, <strong/>, <tt/>, <cite/>, and <span/> within the <p/> and <li/> elements. </p>
|
||||
<p>You may also include tables (these are helpful for listing error codes and such). The <table/> element SHOULD possess a 'caption' attribute that describes the table's contents. Standard XHTML table structure applies (<tr/> defines a row, which contains <th/> elements for header rows and <td/> elements for data rows), and the 'colspan' and 'rowspan' attributes are also available if you need them. Table presentation (such as cellpadding and cellspacing) is handled by the XSLT and CSS stylesheets. However keep in mind that tables weren't meant to display a huge amount of text.</p>
|
||||
<p>The xep.xsl file performs all sorts of magic in converting your XML file into HTML, including creation of the front matter, table of contents, section numbering, notes, and revision history. Feel free to submit patches for this file, but do not commit your modified version to source control.</p>
|
||||
<p>Although HTML is the primary publishing format for XEPs, since 2009 the XMPP Extensions Editor has also published XEPs in the form of PDF file. Keeping that in mind, try to avoid tables with too many columns, which might require wider paper than is normal.</p>
