OpenMetadata vs iot-dc3

OpenMetadata: OpenMetadata is a unified metadata platform for data discovery, observability, and governance, powered by a central repository and column-level lineage. It's a fast-growing open-source project that enables end-to-end metadata management across diverse data services.; iot-dc3: IoT DC3 is an open-source industrial IoT runtime that connects field devices through 36 protocol drivers (Modbus, OPC UA, Siemens S7, MQTT, LoRaWAN and more) and delivers normalized point data to applications through one API. An Agentic Center built on Spring AI and an MCP tool gateway let AI agents query and act on devices with governance.
