Struct Ontology 

pub struct Ontology {
    pub version: String,
    pub semantic_tags: Vec<SemanticTag>,
    pub relationships: Vec<EntityRelationship>,
    pub mappings: Vec<CrossProviderMapping>,
    pub migration_paths: Vec<MigrationPath>,
    pub capabilities: HashMap<String, Vec<String>>,
}

The complete ontology over all provider schemas.

AI agents can query this to:

1. Discover what data is available across providers
2. Understand field semantics and relationships
3. Find equivalent fields across providers
4. Plan data migrations and merges

Fields

version: String

Version of the ontology specification

semantic_tags: Vec<SemanticTag>

All known semantic tags (universal field concepts)

relationships: Vec<EntityRelationship>

Entity type relationships

mappings: Vec<CrossProviderMapping>

Cross-provider field mappings

migration_paths: Vec<MigrationPath>

Known migration paths between schema versions

capabilities: HashMap<String, Vec<String>>

Provider capability matrix (provider → set of capabilities)
