Detailed Description
This feature is a first approach to unified format for all types of bundles(in 0.86 it will support only Journal entries and new library bundles).
Bundle files hierarchy
- MANIFEST EOL-terminalted list of files inside bundle
- METADATA file in INI format which describes bundle
METADATA file
METADATA files could consists of several predefined sections:
- [Metadata*]
- [Activity]
- [Library]
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.
[Metadata] section
This section is mandatory. It describes Datastore metadata fields of final entry in Journal.
| Field | Flags | Notes |
|---|---|---|
| journal_file | optional | if exists, this file will be unpacked while uploading bundle to Journal and current section defines its metadata otherwise defines metadata for bundle itself and bundle will be stored as is in Journal |
| mime_type | mandatory | define metadata for a file which which will be stored in Journal(according to journal_file) |
| * | optional | any Datastore field, predefined or user defined |
METADATA file could have several [Manifest] sections, in that case they would be parted by different suffixes e.g. [Manifest2], [Manifest.additional] etc.
MANIFEST file
File which contains a new-line-terminated list of file names inside bundle.
Benefit to Sugar
Let users export/import Journal objects.
Scope
- deprecate .xol bundles
- deprecate .xoj bundles
- provide unified format for metadata file in .xo bundles which should support
- activities, former .xo bundles (0.88)
- libraries, former .xol bundles (0.86)
- journal entries, former .xoj bundles (0.86)
- make Browse upload object bundles when the server says so
- InfoSlicer generates object bundles in 0.86 environment
How To Test
- Create a new TurtleArt activity
- Upload the new entry to the SL wiki using Browse
- Use Browse to download the entry back to Journal
- Resume it from Journal

Documentation
Release Notes
The Sugar Release Notes inform end-users about what is new in the release. An Example is 0.84/Notes. The release notes also help users know how to deal with platform changes such as ABIs/APIs, configuration or data file formats, or upgrade concerns. If there are any such changes involved in this feature, indicate them here. You can also link to upstream documentation if it satisfies this need. This information forms the basis of the release notes edited by the release team and shipped with the release.
