I/O schema loader + validator for analytics notebooks

Analytic Schema

Note: This project has been discontinued. Please use Contract schema.

Analytic Schema is a lightweight Python package for loading, validating, and building standardized I/O documents for analytics notebooks based on a single, versioned JSON contract that drives both input parsing and output construction.

Description

Analytic Schema centralizes your notebook or script I/O definitions into one authoritative JSON file. From that contract it automatically:

• Generates a complete command-line interface (via argparse) for every input field.
• Parses parameters provided as CLI flags, JSON dictionaries, or JSON files.
• Injects sensible defaults for all optional inputs.
• Performs deep schema validation (type checks, enums, date-time formats, oneOf branches, and no extra fields).
• Builds structured output documents with embedded metadata, SHA-256 hashes for auditability, and a built-in logging mechanism.

With zero dependencies beyond the standard library and pandas, Analytic Schema is ideal for air-gapped notebooks, CI pipelines, or any environment where you need a robust, self-contained I/O layer for cybersecurity analytics.

Dependencies

This project depends only on the Python standard library (>=3.8) and pandas (>=1.0).

Installation

pip install analytic-schema

In your code:

import analytic_schema

Usage

Check out example_usage.py for a guided walkthrough. That script demonstrates how Analytic Schema handles all the I/O boilerplate, to include CLI parsing, default injection, validation, metadata, logging, hashing, and final serialization so you can focus on the core analytic logic.

Background and Motivation

In cybersecurity analytics, consistency and auditability are paramount. Analysts and automation pipelines often spin up dozens of scripts and notebooks, each rolling its own argument parsing, validation, and output formatting. This fragmentation leads to subtle bugs, schema drift, and integration headaches.

Analytic Schema addresses these challenges by elevating your I/O contract to one single JSON schema. This contract drives:

• Uniformity: All analytics share the same field names, types, and defaults.
• Reliability: Fail-fast validation prevents runtime surprises from missing or mistyped parameters.
• Traceability: Inputs and findings are hashed, and logs are captured inline, enabling full audit trails.
• Simplicity: With only the standard library plus pandas, it works in air-gapped environments and keeps your dependencies minimal.

By abstracting away boilerplate, you can focus on detecting and investigating threats, while ensuring your pipelines remain robust, maintainable, and easily integrated.
