UPDATED: XEP-0353 (Jingle Message Initiation)

by Daniel Gultsch

Version 0.8.0 of XEP-0353 (Jingle Message Initiation) has been released. Abstract: This specification provides a way for the initiator of a Jingle session to propose sending an invitation in an XMPP message stanza, thus taking advantage of message delivery semantics instead of sending IQ stanzas to all of the responder's online resources or choosing a particular online resource. Changelog: Adapt usage of JID types to real-world usage: * Send JMI responses to full JID of initiator instead of bare JID * Send JMI <finish/> element to full JID of both parties (melvo) URL: https://xmpp.org/extensions/xep-0353.html Note: The information in the XEP list at https://xmpp.org/extensions/ is updated by a separate automated process and may be stale at the time this email is sent.

Occupant colours

by Dave Cridland

I quite like XEP-0392. I didn't honestly think I would when it first proposed and published, but it's really handy. But, XEP-0392 doesn't - anywhere - specify what the "input" should be. I can see some options: 1) Pick the relevant jid. I'm currently using the bare jid for 1:1 conversations, and the XEP-0045 occupant jid (including nickname) for MUCs. That seems the most obvious, but means nickname changes also change colour. 2) Pick the display name. I could use the name for 1:1 (the one I display, from Roster etc) and the nickname from a MUC. That has the advantage that where those are the same, the colour will be consistent - "Zash" will be coloured the same on all MUCs, for example. 3) Pick the most stable identifier I can. So occupant_id in MUC, though still bare Jid for 1:1. This would mean the bright pink occupant would remain bright pink no matter what nickname change they tried. No escape! Any suggestions? Or doesn't it matter? Dave.

Write-only PubSub node (XEP-0060)

by Schimon Jehudah

Greetings. I am interested to know, whether there is a possibility to create a write-only node. For instance, a node which be written by anyone, and read by selected people, be useful to moderation of contents. Pending urn:xmpp:microblog-await:0 Moderators: read and write Public: write Denied urn:xmpp:microblog-denied:0 Moderators: read and write Public: none Approved urn:xmpp:microblog:0 Moderators: read and write Public: read P.S. The node names are not standard node names. These are node names for the purpose of realization. Kind regards, Schimon

Atom Over XMPP and element atom:link

by Schimon Jehudah

Greetings. I would want to discuss of Atom Over XMPP; that is XEP-0277 and XEP-0472, and subsequently XEP-0501; and the implementation thereof by several publishing platforms. Some publishing platforms utilize RFC 4287 in an invalid fashion, and I would want to advise of a better practice. I do not discuss this over the documentation repository, because I do not think that it is necessary, as this is an issue which concerns to RFC 4287 itself The Atom Syndication Format. atom:content ------------ Section 4.1.2 to RFC 4287 titled by The "atom:entry" Element has this statement. > o atom:entry elements MUST NOT contain more than one atom:content > element. However, there are at least two publishing platforms that violate that principle, and provide two elements of "atom:content"; One "atom:content" element of type="xhtml" and an additional one of type="text" which is not really Plain Text as intended by RFC 4287, but is Markdown Text. I suppose that, the purpose of the extra element is to store the source code of the actual content, to facilitate human interaction with these platforms. It is important to not that the valid values of attribute "type" of element "atom:content" are "text, "html", and "xhtml". atom:link --------- Nevertheless, the element "atom:link" offers two relevant attributes to that would fit perfectly. Attribute "href" (location) to specify the URI to the document. That could also be over FTP, Gemini, HTTP, XMPP, over a PubSub URI for public or private access; and it is particularly helpful, to both developers and people, to access or download the source of a document, instead of extracting it from an XML element; Attribute "rel" (relation) which has various of uses over Atom, HTML, and XML, including paging with rel="next" and rel="previous" (RFC 5005), could be utilized to classify the content of the linked document as a source of a post (i.e. rel="source"); and Attribute "type" (MIME-Type) to set the file type of the content (i.e. type="text/markdown"). Attributes "hreflang" and "title", of element "atom:link", might also be useful, yet these two attributes are not crucial to this discussion. Importance ---------- There are three crucial reasons for that advisory. * Compliance with RFC 4287, as intended; * Better classification of data, as proposed; and * Most importantly, to not confuse developers who want to explore publishing over XMPP; for example, developers of publishing platforms such as Bonfire, Pleroma who are meticulous when they implement standards. Of note ------- I was confused, and almost discouraged, when I first attempted to create a publishing platform, because I tested against platforms that utilize more than a single element of "atom:content", and which one was classified as "text" even though it was not plain text. Respectfully, Schimon
