About
Apache Ossie is an open specification and converter toolkit for exchanging semantic metadata across analytics, business intelligence, and AI systems. Its YAML-based format describes semantic models, datasets, fields, metrics, dimensions, relationships, and SQL expressions in a portable structure. Data and analytics engineers can use compatible implementations to author, translate, and reuse these definitions across connected platforms, supporting consistent business context for reporting and AI-assisted analysis. The project is an open-source community effort under the Apache License 2.0, with available conversions depending on each platform’s implementation.

About
Colrows is an autonomous semantic layer engineered to make enterprise AI reliable at production scale. Enterprise AI initiatives stall when models hallucinate and answers lack auditability. Colrows fixes the context, not the model.
The platform continuously crawls databases, warehouses, catalogs, and documentation to build a dynamic business graph of entities, metrics, and logic. Sitting between enterprise data and AI surfaces, Colrows compiles natural language into governed, auditable SQL query plans. Every output traces directly to a verified single source of truth.
Key capabilities include:
AI Data Analyst: Conversational analytics with end-to-end SQL lineage.
Semantic API: Standardized semantic infrastructure for internal copilots and agents.
Auto-Crawl Engine: Continuous metadata synchronization without manual coding.
Colrows delivers the mathematical accuracy and regulatory defensibility that probabilistic RAG cannot match. It is suited for regulated industries.
