Open Data Schema for Energy - validation and transformation library

ODS-E: Open Data Schema for Energy

ODS-E is an open specification for standardizing energy asset data from IoT devices, enabling interoperability across the renewable energy ecosystem.

Why ODS-E?

• No Vendor Lock-in: Your data works with any ODS-E compatible system
• Faster Integrations: Pre-built transforms for common OEMs (Huawei, Enphase, Solarman)
• Analytics-Ready: Standardized error taxonomy and semantic validation
• Future-Proof: CC-BY-SA licensed specification ensures extensions stay open

Quick Start

pip install odse

from ods_e import validate, transform

# Validate ODS-E data
result = validate("production_data.json")

# Transform from OEM format
ods_data = transform("huawei_export.csv", source="huawei")
