Coordination Layer Algebra ​

admission, permission, access, right, and claim against the network must be distinguished not only by name, but by what does not follow from each of them.

Five different layers ​

1. Admission ​

Answers the question: is the subject admissible for participation in an environmental regime, role, or procedure.

2. Permission ​

Answers the question: is a specific action over a specific target admissible.

3. Access ​

Answers the question: can the subject in fact obtain visibility, reading, or technical reachability of the required surface.

4. Right ​

Answers the question: on what basis does the subject claim the object, the content, or a substantial action.

5. Claim against the network ​

Answers the question: what may the subject demand from the network or operator as a service surface.

What does not follow from what ​

Architecturally, the following negative rules must be retained.

• Admission does not automatically entail permission, access, right, or claim against the network.
• Permission does not automatically entail admission, access, right, or claim against the network.
• Access does not automatically entail admission, permission, right, or claim against the network.
• Right does not automatically entail admission, permission, access, or claim against the network.
• Claim against the network does not automatically entail admission, access, right, permission, or what is substantively true of the object.

What may be conditionally connected ​

These layers may be connected through contour rules, structure, an explicitly declared service profile, or an external basis, but the connection must be explicit.

That is, conditions of the following kind are admissible:

• when a certain admission is present, the subject may obtain a certain access;
• when a certain right is present, the subject may obtain a certain permission;
• when an explicitly declared service profile is present, the subject may obtain a certain claim against the network.

But such links must be declared explicitly. They are not architectural identities.

If this algebra is not named directly, Realith begins to read as a simplified permission system in which:

• participation equals authority;
• visibility equals right;
• right equals a service demand against the network.

That destroys the project's architectural task itself.
