Sugar Network/Resources

The following diagram shows the full list of objects implemented by the Sugar Network API.

Sugar Network objects

Resource.layer

This is an attempt to generalize the idea of user/resource levels with idea that objects should not be removed from the Network immediately (only hidden, and permanently removed by Network administrators). So, every resource is associated with a layer, i.e., it might be visible for observers only if they requested this layer and have permissions to see it.

For now, implemented only the following list of layers, but it might be reused for teachers related workflows later:

• general, the default layer for observers and Network objects; all users can see objects on this layer;
• deleted Network objects' layer will be changed to deleted after removing objects by users.

Context.type

Context types:

• application, software application;
• library, software library;
• activity, Sugar activity;
• article, arbitrary content in a form of article.

Implementation.license

Short license names. The licenses should conform with the Activity Library licensing policy.

Implementation.stability

Stability level of the Implementation. Values conform to 0install stability levels and could be:

• insecure,
• buggy,
• developer,
• testing,
• stable.

Implementation.requires

What Contexts the current one depends on. Value is a dictionary of:

  "<Context-GUID>": {
    "constraints": [{             # optional array of constrains
      "not-before": "<VERSION>",  # the lowest-numbered version that can be chosen
      "before": "<VERSION>",      # this version and all later versions are unsuitable
      }],
    "importance":
      "essential|recommended",    # dependency must be selected or no version is also an option
  }

Artifact.type

The type of the Artifact:

• screenshot, screenshot generated within the Context;
• jobject, Journal object generated by Sugar activity.

Notification.type

• create, object was created;
• update, object's properties were modified;
• delete, object was deleted (hidden);
• vote, object was voted/unvoted.
