README

This package contains the metadata client written in the Go programming language. The metadata client is used by Go services or other Go code to communicate with the EdgeX core-metadata microservice (regardless of underlying implemenation type) by sending REST requests to the service's API endpoints.

How To Use

To use the core-metadata client package you first need to import the library into your project:

import "github.com/Circutor/edgex/pkg/clients/metadata"

As an example of use, to find a device using the Metadata client, first create a new device client (see core-data init.go)

mdc = metadata.NewDeviceClient(params, types.Endpoint{})

And then use the device client to located a device by Device struct (see core-data event.go)

_, err := mdc.CheckForDevice(device)
