AWS IoT TwinMaker exposes the Entity-component model as a REST API :
- ListEntities : Allows you to query the entities and filter by Id, external Id or parent Id
- GetEntity : Retrieves the details of an entity and property values
But I agree, a query interface would be useful in a lot of use cases.
We just launched TwinMaker Knowledge Graph https://aws.amazon.com/about-aws/whats-new/2022/11/twinmaker-knowledge-graph-generally-available-aws-iot-twinmaker/. We are using partiQL as the query language. Visit our documentation https://docs.aws.amazon.com/iot-twinmaker/latest/guide/tm-knowledge-graph.html for more details.
