Concept: Person

Purpose: To represent a single user or entity, even if they have multiple public keys and/or multiple authorships.

State: A person is a combination of one or more authors, semantically linked through cross-labeling with the "approve" label.

Actions:

- Get person: Retrieves the person associated with a public key or author.

- Get all persons: Retrieves all persons in the system.

Operational Principle:

- A person is a combination of one or more authors, semantically linked through cross-labeling with the "approve" label.

- A person is uniquely identified by the hash of its corresponding item in the system.

Example:

A user could create two public keys and use them to create two different pieces of content. The two authors of the content would be merged into a single person, since they are both associated with the same user.

Benefits of the person concept:

- The person concept provides a way to represent a single user or entity, even if they have multiple public keys and/or multiple authorships.

- The person concept can be used to implement a variety of features, such as user profiles, social networking, and access control.
