Taxi - Describe How Your APIs and Data Relate

Taxi is an open-source language (Apache 2.0) for describing APIs, data models, and how data relates across an entire ecosystem. TaxiQL is a declarative query language that lets consumers define the data they want while Taxi handles orchestration across REST APIs, databases, Kafka topics, gRPC services, and S3 buckets. Taxi eliminates manual integration code by using semantic type annotations to automatically discover data paths and adapt to evolving API schemas.
