Concept: Label
Purpose: To provide a way to attach labels to items in a secure and verifiable manner.
State: A label is an item that contains a reference to one or more parent items, which are the subjects of the label, and one or more labels. Labels are enclosed in a PGP enveloped and signed to match the public key of the user who created the label.
Actions:
Create label: Creates a new label and assigns it a hash.
Get label: Retrieves a label by its hash.
Update label: Updates an existing label.
Delete label: Deletes a label.
Operational Principle:
Labels are identified by their hash.
Labels contain a reference to one or more parent items and one or more labels.
Labels are enclosed in a PGP enveloped and signed to match the public key of the user who created the label.
Example:
A user could create a label for a public key to indicate that the public key is owned by a trusted friend. The label would contain a reference to the public key and a label indicating that the public key is trusted.
A user could also create a label for a user post to indicate that the post is about a particular topic. The label would contain a reference to the user post and a label indicating the topic of the post.
Labels can be used to categorize and organize items in a system. They can also be used to provide additional information about items. For example, a label could be used to indicate that an item is sensitive or confidential.
The use of PGP enveloped and signed labels ensures that labels are secure and verifiable. Only the user who created a label can update or delete the label. Only users with the public key of the user who created a label can verify the label.
