Sugar Network/Resources

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

Sugar Network objects

Resource.authority

A dictionary of User guids and integers with roles information. Role value is a bit-wise ORed value of the following constants:

• 1
  corresponding user is the original author of the object; if it is not set, user is only a maintainer, e.g., an uploader of a book which has its original authors; if it is set, user name (not guid) will be automatically added to the author property in addition to directly set authors.

Resource.layers

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:

• public, object is visible for everyone;
• deleted Network objects' layer will be changed to deleted after removing objects by users.

Context.type

Context types:

• activity, Sugar activity;
• project, general purpose context;
• package, GNU/Linux package metadata;
• content, content like PDF files.

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.

Notification.type

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

Feedback.type

• question
• idea
• problem

Artifact.type
