  • Packages affected: python-contacts-api, dbus-contacts-api, gtk-contacts-picker, erlang, couchdb, couchdb-bin, ubuntu-couchdb, couchdb-oauth, couchdb-history, ubutuone-sync-ui, evolution-couchdb, akonadi-couchdb, tomboy-couchdb, firefox-bookmarks-couchdb, python-couchdb, couchdb-glib, dbus-couchdb, python-couchdb-records-api, dbus-couchdb-records-api, icontool, ubuntuone-client, ubuntuone-storage-protocol, python-oauth, ubuntuone-screensharing, ejabberd, python-configglue, gwibber-couchdb, python-pyinotify


Ubuntu One provides capabilities for the Ubuntu desktop as well as extended capabilities via optional online services. Integrating Ubuntu One capabilities with the Ubuntu desktop will provide storage sharing & synchronization (across a LAN and (optionally) the Ubuntu One cloud), screen sharing, and data (contacts, notes, Firefox bookmarks) sharing & synchronization via CouchDB.

Release Note


User stories



File Sharing & Synchronization

File sharing and syncronization allows users to share and synchronize files across their local network. An optional capability will allow users to easily share and synchronize files across the Internet using the Ubuntu One online service.

The Ubuntu One client will no longer use a client applet (as is the case with the current beta). Instead, the client will use downloads, FUSA, and standard Ubuntu messaging indicators.


  • icontool
  • ubuntuone-client
  • ubuntuone-storage-protocol
  • python-configglue
  • python-pyinotify

Screen Sharing

Provides screen sharing between two desktops using Empathy, Telepathy. The "Share My Desktop" dialog will be unaffected. An optional Ubuntu One service will provide a proxy (utilizing ejabberd on the server) to allow users to more easily share their screens across the Internet.

  • ejabberd

Data Sharing & Synchronization


Overview: Apache CouchDB is a distributed, fault-tolerant and schema-free document-oriented database accessible via a RESTful HTTP/JSON API. CouchDB is the database for Ubuntu One data sharing and synchronization capabilities.

Each user will run their own instance of CouchDB, which is different than the standard install of the current CouchDB package. There is also a need to setup various CouchDB configuration files, design docs, and triggers. Additional capabilities will be added to CouchDB, including OAuth support and document history.

In order for developers to more easily use CouchDB in their applications, we will provide libraries for a variety of languages and environments, including Python, DBUS, and GTK (GLib).


  • erlang
  • couchdb
  • couchdb-bin
  • ubuntu-couchdb
  • couchdb-oauth
  • couchdb-history
  • ubuntuone-sync-ui
  • python-couchdb
  • couchdb-glib
  • dbus-couchdb
  • python-couchdb-records-api
  • dbus-couchdb-records-api


Providing a CouchDB contacts database that all Ubuntu applications can use is one of the key applications of the Ubuntu One data sharing and synchronization capability. Integration with Evolution, Akonadi, and Gwibber will store contacts in CouchDB. Developers of GTK applications will have a GTK widget which can provide their applications with a way to easily lookup/select contacts from the contacts CouchDB database. There will also be a contacts API for Python and DBUS, which will allow developers to use the CouchDB contacts database without worrying about the underlying details of CouchDB and the contacts schema.


  • evolution-couchdb
  • akonadi-couchdb
  • gwibber-couchdb
  • python-contacts-api
  • dbus-contacts-api
  • gtk-contacts-picker

Bookmarks (Firefox)

A Firefox bookmarks synchronization and sharing extension will store Firefox bookmarks in CouchDB, which will provide sharing and synchronization capabilities.


  • firefox-bookmarks-couchdb

Notes (Tomboy)

Tomboy will use CouchDB for storing its data which will provide sharing and synchronization capabilities.


  • tomboy-couchdb


The packages below will provide general Packages:

  • python-oauth
  • configglue


This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like:

UI Changes

Should cover changes required to the UI, or specific UI that is required to implement this

Code Changes

Code changes should include an overview of what needs to change, and in some cases even the specific details.



  • data migration, if any
  • redirects from old URLs to new ones, if any
  • how users will be pointed to the new way of doing things, if necessary.

Test/Demo Plan


Unresolved issues

This should highlight any issues that should be addressed in further specifications, and not problems with the specification itself; since any specification with problems cannot be approved.
