This module contains the contract models used to describe data as it is passed via Request/Response between various EdgeX Foundry services. It also contains service clients for each service within the edgex-go repository. The definition of the various models and clients can be found in their respective top-level directories.

The default encoding for the models is JSON, although in at least one case -- DeviceProfile -- YAML encoding is also supported since a device profile is defined as a YAML document.

• Make sure you're using at least Go 1.11.1 (EdgeX currently uses Go 1.15.x) and have modules enabled, i.e. have an initialized go.mod file
• If your code is in your GOPATH then make sure GO111MODULE=on is set
• Run go get github.com/edgexfoundry/go-mod-core-contracts
  • This will add the go-mod-core-contracts to the go.mod file and download it into the module cache
