Struct SemanticTag 

pub struct SemanticTag {
    pub tag: String,
    pub description: String,
    pub canonical_type: DataType,
    pub entity: EntityType,
    pub related_tags: Vec<String>,
}

A semantic tag represents a universal concept that may appear under different field names in different providers.

Example: The concept “session creation time” is stored as:

• creationDate in Copilot Chat
• dateCreated in Continue.dev
• timestamp (of first message) in Claude Code

The semantic tag created_at unifies all of these.

Fields

tag: String

Canonical tag name (e.g., “created_at”, “session_id”, “message_text”)

description: String

Human-readable description

canonical_type: DataType

The universal data type for this concept

entity: EntityType

Entity type this tag belongs to

related_tags: Vec<String>

Related tags (e.g., “created_at” is related to “updated_at”)
