Meaning of Metamodel

1. Metamodel and cognition

1.1. Cognitive systems may be self-explanatory

Putting the metamodel into the cognitive system, the following viewpoints can be seen.

Cognition can be realized through algorithms. The basic operations of cognition are distinction and labeling (naming).
Cognitive systems are self-explanatory. Self-explanatory means that in a cognitive system, any knowledge in the system can be explained by the knowledge within the system, without the need for knowledge outside the system.

The above viewpoints are seen through the properties of the metamodel. The properties of the metamodel are as follows, which can be verified in the model editor.

Any model can be edited directly or indirectly through the metamodel.
Any model can be explained directly or indirectly using the metamodel.
The metamodel can be edited by itself, and it can also explain itself.

1.2. Why can we see it?

If it is feasible to put the metamodel in the cognitive system to explain the cognitive system, then the metamodel is the first knowledge in the system. Since it is the first knowledge, there is no knowledge earlier than it, so the metamodel cannot be proved by knowledge other than the metamodel.

1.3. Missing parts and the purpose of the metamodel

Metamodels and dynamic models alone cannot build a cognitive system because the following key parts are missing.

Specific methods of distinction and labeling. How to distinguish things, how to name a thing, etc.
Validity test of knowledge. Simply put, in dreams and fantasies, you can make various explanations for a thing, but whether these explanations are valid generally needs to be verified in reality.

Above, artificial intelligence based on large models can distinguish and name things, and validity testing can be understood as writing practical programs. Therefore, dynamic models are suitable for combining with artificial intelligence and are suitable for writing various artificial intelligence application scenarios.

1.4. Is it applicable to human cognition?

It may be applicable because the properties of the metamodel coincide with the properties of "Tao" and "God".

2. Coincidence of metamodel

2.1. Virtual world

As a programming method, dynamic models can be used to write complex systems. When the system is complex enough, it can be imagined as a virtual world.

2.2. Metamodel and Laozi’s coincidence

Laozi said: "The beginning of the nameless world is the mother of all things with names."

In a virtual world written using a dynamic model, any object can theoretically be edited directly or indirectly through a metamodel, and the metamodel is the first model in the virtual world. The basic function of the metamodel is naming, so there is a coincidence between the metamodel and Laozi's words.

Laozi said: "Tao gave birth to one, one gave birth to two, two gave birth to three, and three gave birth to all things."

In the dynamic model, the role of the metamodel is to edit the class model, and then the object model can be edited through the class model. All kinds of things in the system can be edited in this way. Since the metamodel can be the first model in the system, because the metamodel can be regarded as one, the class model can be regarded as two, and the object model can be regarded as three, everything is a system composed of various objects.

2.3. The coincidence of metamodel and "God"

In the virtual world written using the dynamic model:

The metamodel is the creator of the world
Because any object in the virtual world can be edited directly or indirectly through the metamodel.
The metamodel is its own parent and child
The metamodel can be edited by itself, so it is its own parent and child.

The properties of the above metamodel coincide with the properties of "God".

3. Demonstration

The properties of the metamodel are the key to this article. This property is reflected in the model editor. The properties of the metamodel are demonstrated through a video.

3.1. Any model can be edited directly or indirectly through the metamodel

The process of editing the model is to first use the metamodel to edit the class model, and then edit the object model through the class model. For example, use the metamodel to edit people (classes), and then edit Zhang San (objects) through people.

Because the class model can be created and modified at any time through the metamodel, so through this method, theoretically any model can be edited directly or indirectly through the metamodel.

In the video above, MetaDescriptor3 is a metamodel.

3.2. Metamodels can edit themselves

It should be noted that there can be multiple metamodels, and their basic properties are the same, that is, they can directly or indirectly edit any model, and they can also edit themselves.

In the following demonstration, we edited a simple metamodel MetaThing1 using the MetaDescriptor3 metamodel, and then used this simple metamodel to edit a metamodel MetaThing2 that is basically the same as it.

3.3. Name

Through the above video, we can find that the basic function of MetaThing1 and MetaThing2 is to name attributes and nodes. This corresponds exactly to Lao Tzu's "Name is the mother of all things".
