WARNING: This Standards-Track document is Experimental. Publication as an XMPP Extension Protocol does not imply approval of this proposal by the XMPP Standards Foundation. Implementation of the protocol described herein is encouraged in exploratory implementations, but production systems are advised to carefully consider whether it is appropriate to deploy implementations of this protocol before it advances to a status of Draft.

1. Introduction

The PEP Native Bookmarks (XEP-0402) [1] defines a way to store Bookmarks using user PEP nodes and brings a support for extensions

Some users might be interested to pin some important Bookmarks when managing them.

2. Requirements

This extensions allow clients to pin important bookmarks.

3. Protocol

When saving a PEP Native Bookmarks (XEP-0402) [1] pinned item the client MUST add a new 'pinned' element within the 'extensions' element having the 'urn:xmpp:bookmarks-pinning:0' namespace.

Example 1. Client adds a new bookmark
<iq from='juliet@capulet.lit/balcony' type='set' id='pip1'>
  <pubsub xmlns='http://jabber.org/protocol/pubsub'>
    <publish node='urn:xmpp:bookmarks:1'>
      <item id='theplay@conference.shakespeare.lit'>
        <conference xmlns='urn:xmpp:bookmarks:1'
                    name='The Play&apos;s the Thing'
                    autojoin='true'>
          <nick>JC</nick>
          <extensions>
            <pinned xmlns='urn:xmpp:bookmarks-pinning:0'/>
          </extensions>
        </conference>
      </item>
    </publish>
    ...
  </pubsub>
</iq>

4. Business Rules

When handling a pinned item, a client SHOULD prioritize it and treat it as important. A client MAY display it using visual specificities (e.g., ordering, icon, color) to differenciate it from non-pinned items.

5. Security Considerations

See considerations in PEP Native Bookmarks (XEP-0402) [1].

6. IANA Considerations

This document requires no interaction with the Internet Assigned Numbers Authority (IANA) [2].

7. XMPP Registrar Considerations

7.1 Protocol Namespaces

This specification defines the following XML namespace:

The XMPP Registrar [3] includes this namespace in the registry located at <https://xmpp.org/registrar/namespaces.html>, as described in Section 4 of XMPP Registrar Function (XEP-0053) [4].

7.2 Protocol Versioning

If the protocol defined in this specification undergoes a revision that is not fully backwards-compatible with an older version, the XMPP Registrar shall increment the protocol version number found at the end of the XML namespaces defined herein, as described in Section 4 of XEP-0053.

8. XML Schema

<?xml version='1.0' encoding='UTF-8'?>

<xs:schema
    xmlns:xs='http://www.w3.org/2001/XMLSchema'
    targetNamespace='urn:xmpp:bookmarks-pinning:0'
    xmlns='urn:xmpp:bookmarks-pinning:0'
    elementFormDefault='qualified'>

  <xs:annotation>
    <xs:documentation>
      The protocol documented by this schema is defined in
      XEP-0402: http://www.xmpp.org/extensions/xep-0402.html
