Module contents

Activity Metadata

Your activity/activity.info file must have these metadata keys after an [Activity] header on the first line:

• name - the name of the activity, shown by Sugar in the list of installed activities, e.g. Browse,

• activity_version - the version of the activity, e.g. 1, 1.2, 1.2.3, 1.2.3-country, or 1.2.3~developer,

• bundle_id - the activity bundle identifier, using [Java package naming conventions] (http://en.wikipedia.org/wiki/Java_package#Package_naming_conventions), should conform to the [D-Bus specification for message protocol names] (http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names) (hyphens are not allowed), usually an organisation or individual domain name in reverse order, e.g. org.sugarlabs.Name,

• license - an identifier for the software license of the bundle, either a Fedora License Short Name, (e.g. GPLv3+) or an SPDX License Identifier, with an optional or later version suffix, e.g. GPL-3.0+, and multiple licenses are to be separated with semicolons,

• icon - the icon file for the activity, shown by Sugar in the list of installed activities,

• exec - how to execute the activity, e.g. sugar-activity3 module.Class (For activities written for Python 3), sugar-activity module.Class (For activities written for Python 2)

Optional metadata keys are;

• summary - a short summary of the activity that may be displayed in the List or Home Views,

• mime_types - list of MIME types supported by the activity, separated by semicolons. Your read_file method must be able to read files of these MIME types. Used to offer your activity when opening a downloaded file or a journal object.

• url - link to a home page or user documentation on https://help.sugarlabs.org/,

• repository - link to repository for activity code, for use by git clone,

• single_instance - if yes, only a single instance of an activity should be started at any one time, and if another instance is requested the existing instance shown,

• max_participants - maximum participants for sharing an activity,

• tags - a semicolon or whitespace delimited list of keywords that

  describe the activity. Suggested keywords are Programming, Robotics, Internet, Science, Maths, Language, Geography, Game, Documents, Music, Media, Art, Teacher, or System,

• show_launcher - if set to “no”, the activity is not shown in list view,

Deprecated metadata keys are;

• category or categories - aliases for tags,

• website - alias for url,

• update_url - the updater no longer uses this.

AppStream Metadata

AppStream is a standard, distribution independent package metadata. For Sugar activities, the AppStream metadata is automatically exported from the activity.info file by the bundlebuilder during the install step.

In order to be compliant with AppStream, activities must have the following metadata fields under the [Activity] header (of the activity.info file):

• metadata_license - license for screenshots and description. AppStream requests only using one of the following: CC0-1.0, CC-BY-3.0, CC-BY-SA-3.0 or GFDL-1.3

• description - a long (multi paragraph) description of your application. This must be written in a subset of HTML. Only the p, ol, ul and li tags are supported.

Optional metadata key:

• screenshots - a space separated list of screenshot URLs. PNG or JPEG files are supported.
