@cpms/data

Data Protocol v1.1.1 packaged for npm. It validates dataset manifests, runs pluggable validators, diffs schema revisions, and synthesizes migration plans while remaining zero-dependency.

Install

pnpm add @cpms/data
# or
npm install @cpms/data

Usage

import { createDataProtocol } from '@cpms/data';

const protocol = createDataProtocol({
  dataset: { name: 'users' },
  schema: {
    fields: {
      user_id: { type: 'string', required: true },
      email: { type: 'string', pii: true }
    },
    primary_key: 'user_id'
  }
});

const result = protocol.validate(['core.shape', 'governance.pii_policy']);

Features

• Immutable factory via createDataProtocol.
• Built-in validators for schema shape, keys, governance, operations, and catalog metadata.

• Catalog analysis hooks for URN alignment.
• Deterministic hashing and circular-safe cloning.

Scripts
