pyGAEB: The Python Library That Unlocks GAEB Construction Data

pyGAEB is an MIT-licensed Python library that parses, validates, classifies, and writes GAEB DA XML files across all versions (2.0–3.3) and exchange phases used in German-speaking construction procurement. It provides a unified Pydantic domain model with Decimal-based arithmetic, tolerant parsing for malformed files, and optional LLM-powered item classification via LiteLLM for enriching line items with semantic types like Door or Wall.
