Navigation instructions for Atom Over XMPP (XEP-0277 and XEP-0472)
by Schimon Jehudah 09 Nov '25

09 Nov '25

Good day. About ===== I have recently suggested at project Movim to add navigational instructions to Atom entries (i.e. posts). I am still experimenting it, and it currently seems useful. Technicality ============ The idea is realized in a similar fashion to the classification of comments node with rel='replies' and title='comments'. https://xmpp.org/extensions/xep-0277.xml#comments Navigation ========== I advise to enable navigational instructions with rel='navigation' and title='previous' and title='proceed', and perhaps also title='index'. At the bottom of this page there are proceed or previous links to navigate and are generated from the instructions proposed above. https://journal.woodpeckersnest.eu/posts/2024-11-05-xmpp-as-the-internet/ Advantages ========== Navigational instructions would conveniently facilitate the creation of a CMS even over a single PEP node, without a compulsory need of having a PubSub service with multiple nodes to do so, by relating from post to post from within each posts. Navigational instructions would also incentivise the creation of articles that are segmented into parts of a series of posts, and portability thereof. Kind regards, Schimon
