ODCS Native Data Structures

This module provides native Rust types that model the ODCS (Open Data Contract Standard) v3.1.0 specification accurately. These types preserve the three-level hierarchy:

1. Contract Level (ODCSContract) - Root document with metadata
2. Schema Level (SchemaObject) - Tables/views/topics within a contract
3. Property Level (Property) - Columns/fields within a schema

Design Goals

• Zero data loss: Full round-trip import/export without losing metadata
• Multi-table support: Native support for contracts with multiple schema objects
• Nested properties: Proper hierarchical representation for OBJECT and ARRAY types
• Format mapping: Clean mapping from Avro, Protobuf, JSON Schema, OpenAPI via custom properties
• Backwards compatibility: Converters to/from existing Table/Column types

Example

use data_modelling_core::models::odcs::{ODCSContract, SchemaObject, Property};

// Create a contract with two tables
let contract = ODCSContract::new("ecommerce", "1.0.0")
    .with_domain("retail")
    .with_status("active")
    .with_schema(
        SchemaObject::new("orders")
            .with_physical_type("table")
            .with_properties(vec![
                Property::new("id", "integer").with_primary_key(true),
                Property::new("customer_id", "integer").with_required(true),
                Property::new("total", "number"),
            ])
    )
    .with_schema(
        SchemaObject::new("order_items")
            .with_physical_type("table")
            .with_properties(vec![
                Property::new("id", "integer").with_primary_key(true),
                Property::new("order_id", "integer").with_required(true),
                Property::new("product_name", "string"),
            ])
    );

assert_eq!(contract.schema_count(), 2);
