RFC 6121 section 8.5 "active resource" and "Connected Resource"

by Guus der Kinderen

Hi, Section 8.5.4 provides a summary of earlier sections. It uses the term "active resource" twice. This term is not used in any of the earlier sections. Conversely, the earlier sections use the term "Connected Resource" a couple of times. A "Connected Resource" is defined by RFC6121/6120 as "[has] bound a resource to the stream" Although the term "Connected Resource" is used in section 8.5, none of the specifications therein seem to apply to Connected Resources. The usage of the term "active resource" in section 8.5.4 could be an artifact of RFC3921/3920, which defines an "active resource" as: "Upon establishing a session, a connected resource (in the terminology of [XMPP-CORE]) is said to be an "active resource." Although section 8.5 advertises that it will define how stanzas related to connected resources are to be processed ("If there is at least one available resource or connected resource, how the stanza is processed depends on the stanza type.") it does not seem to do that. All definitions seem to depend on having at least one available resource (which is defined as a connected resource that has sent initial presence), leaving scenarios in which only connected resources are present, undefined. Am I misinterpreting this? If not, is this something that should be cleared up (or explicitly be left undefined)? As a practical example of a question that I believe is left unanswered: How should a server process a message stanza of type 'normal', addressed to a bare JID that represents a local user (the scenario of section 8.5.2.1.1 of RFC 6121) if the corresponding user only has one or more Connected Resources (but not any Available Resources)? I believe that there are many possible variations on this question, I'm limiting it to one to illustrate the larger issue that I described in this email. For additional context: this was discussed in the XSF's Discussion MUC earlier. Logs of that conversation can be found at https://logs.xmpp.org/xsf/2025-05-28#2025-05-28-a5d887bd6428222c Kind regards, Guus

Situation of DOAP

by Schimon Jehudah

Good evening. I am working on a Python script which generates an Atom Syndication Format XML feed from XMPP DOAP files. I will further add to it an XSLT stylesheet to transform it to XHTML. I have attached that script, for those who are inqusitive about it. Problems -------- However, I did notice, that some DOAP files are not updated, and some are missing information. Proposal -------- I would suggest to add attributes for types of links (i.e. Gemini, HTTP, PubSub, etc.), because in near future, resources such as homepage, bug-database, developer-forum, developer-support, etc. will be hosted on PubSub services over XMPP, instead of HTTP. Question -------- Is there an automated DOAP generator software or service? Conclusion ---------- If there is no automated service yet, then I would create an XHTML software with forms that would do so. Afterwards, I would also create an XMPP service with Data Forms for that purpose. Please advise. Kindly, Schimon

We need more mailing-lists

by Schimon Jehudah

Good day. Please create "development" (or "jdev") and "general" (or "talk") mailing-lists. I sense that these are required. DEVELOPMENT ----------- I have many questions about XMPP development and concerns that are indirectly related to XMPP. I urgently need to have a mailing-list for development, as most of my questions aer not directly related to standard. GENERAL ------- A general mailing-list be useful to converse of any other concern, including welcoming people who have interest in XMPP, of any sort. Kind regards, Schimon

Advise for HTTP framework

by Schimon Jehudah

Good evening. I intend to create a ptivate publishing system (i.e. journal) which is based upon Atom Over XMPP (XEP-0277 and XEP-0472), and which would interact with Libervia and Movim. I usually utilize FastAPI, yet I would want to know of other possible frameworks which you think that might be more preferable for that task. Reference: https://git.xmpp-it.net/sch/Rivista Kind regards, Schimon.
