In fact, this feature is an end users oriented(technically we not invent super format for various types of content, just unified sugar wrapper). Users all time know that there is only one type of sugar objects, they see it as a Journal item, one file with suffix ''.xo'' in non-sugar environments etc. So they need only upload this file to Journal and click to activate it.

At present we have several file types that user can encounter out of sugar:
At present, we have several file types that user can encounter out of sugar:
* activity bundles(.xo)
* activity bundles(.xo)
* content bundles(.xol)
* content bundles(.xol)
* journal bundles(.xoj)
* journal bundles(.xoj)
All these files have different suffixes and after uploading to Journal have different behaviour.
All these files have different suffixes and after uploading to Journal have different behaviour.
Sugar Bundles are intended to unify object related workflow:
* one type of objects out of sugar - files with ''.xo'' suffix
* one type of behaviour after uploading such files to the Journal - you need to click on object in Journal to activate it
So, Sugar Bundles not only changes import/export part of sugar but also change lauch workflow, uploaded objects from ''.xo'' files could be:
* ''activity_id'' less Journal entries, launch some activity to open this object
** just various files that were created out of sugar
** former Library bundles will be opened in Browse
* Journal entries with ''activity_id'', launch poper activity to open this object
* activities, launch it with newly created object
=== Specification ===
Sugar bundle should have METADATA file in the top directory(or in <some_name>/ directory) of .xo bundle. This file is in [http://docs.python.org/library/configparser.html INI] format which describes how to setup bundle.
METADATA file can have one or several sections(depends on content) that describe metadata fields of final entry(ies) in Journal and other data that could be useful for sugar(depends on content).
{| border=1 cellpadding=3 style="border: 1px solid white; border-collapse: collapse; background: #e3e4e5;"
|-style="background:#787878; color: white;"
! Field
! Flags
! Notes
|-
| ''entry''
| optional<br>(depends on content)
| defines access point within the bundle(e.g. index.html for library bundles)
|-
| ''mime_type''
| mandatory
| define MIME type for final Journal entry
|-
| ''uid''
| ignored
|-
| ''*''
| optional
| any [[Features/Plain_Query_Format#System_terms|system]], [[Features/Plain_Query_Format#Users_predefined_terms|users predefined]] and arbitrary Datastore field
|-
| ''*''
| optional
| any tag, depends on content(inherited from activity bundles etc.)
|-
|}
Any field in ''METADATA'' file can have ''_file'' suffix, in that case content of this field(substring w/o ''_file'' suffix) will be fetched from file inside of the bundle.

So if one user uploaded Journal object(any type - activity, activity object, content library etc.) to the web, another user can download/transfer-through-many-non-sugar-environments it and open in his sugar environment with keeping all metadata(he will get the same Journal entry).

We can also collect users object on public server like ASLO to have server like sharing feature.
