OData NDC

A Native Data Connector (NDC) for OData APIs, specifically for those adhering to OData v4.01.

See the example/ directory for sample metadata corresponding to the OData reference service: TripPin.

Getting started

• just config-server will run the configuration server.
• just update will use the running configuration server to update a given metadata file (or, by default, example/metadata.json).
• just start will run the NDC with the given metadata file (or, by default, example/metadata.json).

A Docker setup is also provided: docker compose up will run the NDC with the example configuration, or whatever file METADATA_PATH points to.
