This document defines an extensible bookmark element pointing to a Pubsub node, compatible with the extensions defined in PEP Native Bookmarks (XEP-0402) [1].
This bookmarks elements are always listed as Pubsub items allowing an entity to discover and explore a list of bookmarks listed by another entity. For example in Server-side spaces (XEP-0503) [2] it allows a Space to list Pubsub nodes besides MUCs in a Space and in Pubsub Subscription (XEP-0330) [3] it allows an entity to share Pubsub nodes it subscribed to.
Information about a Pubsub Node Bookmark is provided by the entity. The bookmark container is defined as a classic <pubsub-node/> element, qualified by with theses specific constraints:
| Name | Type | Description | Support |
| jid | attribute | The node jid address | REQUIRED |
| node | attribute | The node node | REQUIRED |
| <extensions/> element | XML Elements | A set of child elements (of potentially any namespace). Clients MUST preserve these (particularly preserving unknown elements) when editing items. | OPTIONAL |
The aim of this XEP is to allow an entity to handle a list of subscriptions. To simplify the managment of this list the ID of the Publish-Subscribe (XEP-0060) [4] items MUST be the Pubsub URI of the node as defined in Publish-Subscribe (XEP-0060) [4]#impl-uri without the 'xmpp:' part.
