Thing Model Catalog CLI

Find, use and contribute device descriptions for industrial IoT devices!

⚠ This software is experimental and may not be fit for any purposes.

The Thing Model Catalog Command Line Client, or tmc for short, is a tool for browsing, consuming, contributing and serving Thing Models.

Thing Models are simple device descriptions specified in the W3C Thing Description standard. Thing Models are to Thing Descriptions what classes are to instances in programming languages.

Thing Models let you describe industrial devices using a simple standardized JSON-based format, which is independent of the communication protocol. This enables a uniform access layer to the fragmented industrial protocol landscape we encounter today.

Thing Descriptions are to Modbus, BACnet, MQTT, DNP3 ... what HTML is to HTTP.

Installation

1. Download the latest release for your operating system and architecture
2. Optionally rename to tmc to remove os/arch postfixes
3. Give it execution rights and move to a folder that is in your PATH

Quick Start

The tmc helps you to interact with a Thing Model catalog, which may be hosted on any git forge like github or create your own catalog in a git repository of your choosing.

To enable a culture of sharing, we provide a canonical repository at [], but feel free to create your own open or private catalog as well.

To integrate publicly available and your own private Thing Models into your product, the tmc can be run as a server, exposing a REST API that can be protected with JWT tokens.

Configure Autocompletion

1. Read the help of the completion command to find out which shells are supported

tmc completion -h

1. Follow the instructions of the shell specific help text

tmc completion <shell> -h

Browse the canoncial Catalog

1. Configure the canonical repository

tmc repo add --type http thingmodels 'https://raw.githubusercontent.com/wot-oss/thingmodels'

1. List the contents of the canonical catalog

tmc list

The listed names are formatted as follows

<author>/<manufacturer>/<model>

You can specify a part of that path after the list command to filter the list for only parts of the list tree (use tab to auto-complete path parts):

tmc list nexus-x/siemens

List Versions

Every model entry in the list may contain multiple versions, reflecting the evolution of the Thing Model (bugfixes, additions, changes in the device itself ...). List the available versions with the versions command:

tmc versions <name>

Fetch a Thing Model

Like what you see? Fetch and store locally using the fetch command. It will print the Thing Model to stdout to enable unix-like piping:

tmc fetch <NAME>

If you just specify the name, the cli will fetch the latest version automatically. If you want to fetch a specific version, append the version string to the name, separated by a colon:

tmc fetch <NAME>:<SEMVER>

To store the Thing Model locally instead of printing to stdout, specify the -o flag and point it to a directory:

tmc fetch <NAME> -o .
