Concept: Item

Purpose: To provide a base data type for most other things in the system.

State: An item is a piece of data that is identified by its hash. It can store any type of data, such as text, images, or videos.

Actions:

- Create item: Creates a new item and assigns it a hash.

- Index item: Adds item’s properties to the index database and web pages.

- Remove item: Removes the item’s data and properites, but retains notarization reference.

Operational Principle:

- Items are identified by their hash.

- Items can store any type of data.

- Items can be created, retrieved, updated, and deleted.

Example:

A public key could be represented as an item. The item would store the public key data and the hash of the public key would be used to identify the item.

A user post could also be represented as an item. The item would store the post data and the hash of the post would be used to identify the item.

Labels could also be represented as items. The item would store the label data and the hash of the label would be used to identify the item.

The item concept is a powerful way to represent and manage different types of data in a system. It is flexible and scalable, and it can be used to implement a variety of features.

Here are some additional benefits of the item concept:

- It provides a common way to represent different types of data in a system.

- It makes it easy to add new types of data to the system without having to make major changes to the existing codebase.

Overall, the item concept is a valuable tool for designing and developing software systems.
