What is Semantic?
Semantic — The meaning layer of an agentic system, where an agent represents and resolves what things mean rather than how they are spelled.
Semantic is the primitive that answers what does this actually mean? for an autonomous system. Agents act on intent and relationships, so they need a representation of meaning that holds even when the surface wording changes.
It sits beneath retrieval and reasoning. Where syntax matches strings, semantics matches concepts, and every higher reasoning step depends on getting that mapping right.
Where semantic sits in the stack
In the four-layer architecture of the agentic web, semantic is a Cross-cutting concept — it applies across every layer of the stack. See the thesis for how the layers compound.
