CAMSAI Standards

The CAMSAI Standards repository defines and maintains a set of consistent schemas, validation tools, and data standards for materials science data and AI-driven research workflows. These standards ensure the interoperability, reproducibility, and scalability of materials-related datasets and applications across the CAMSAI ecosystem.

---

Purpose

This repository provides:

• Data Models: Pydantic-based schemas for defining and validating data structures.
• Validation Utilities: Tools to ensure data compliance with established standards.
• Interoperability Support: Standards that facilitate seamless collaboration between different systems, tools, and workflows.

---

Key Features

1. Schema Definitions

   • Comprehensive data models for common materials science objects.
   • Designed for compatibility with CAMSAI workflows and third-party applications.

2. Validation Tools

   • Python utilities to validate data against the defined standards.
   • Example workflows for integrating validation into your projects.

3. Interoperability

   • Supports data exchange and integration across various CAMSAI and external platforms.

---

Repository Structure

• src/py/camsai/standards
  Contains Python files defining the Pydantic schemas for various data models by source/provider (e.g., Mat3ra.com).

---

Installation

Using pip:

You can install the repository using pip (requires Python 3.8+):

pip install camsai-standards

or from GitHub:

pip install git+https://github.com/camsai/standards.git

In JupyterLite:

Install the package in a Pyodide-based JupyterLite environment:

await micropip.install("camsai-standards")

Usage

Example: Validating a Material Schema

from camsai.standards.mat3ra import Mat3raMaterialSchema
from camsai.standards import is_valid

# Example material data
material_data = {...}

# Validate data
if is_valid(Mat3raMaterialSchema, material_data):
    print("Valid material data")
else:
    print("Invalid material data")

Example: Using Predefined Examples

from mat3ra.esse.data.examples import EXAMPLES

example_material = next((e for e in EXAMPLES if e["path"] == "material"), None)["data"]
print(example_material)
