twined is a library to help create and connect Digital Twins and data services.
“Twined” [t-why-nd] ~ encircled, twisted together, interwoven
A digital twin is a virtual representation of a real life being - a physical asset like a wind turbine or car - or even a human. Like real things, digital twins need to interact, so can be connected together, but need a common communication framework to do so.
twined helps you to define a single file, a “twine”, that defines a digital twin / data service. It specifies specifying its data interfaces, connections to other twins, and other requirements.
Any person, or any computer, can read a twine and understand what-goes-in and what-comes-out. That makes it easy to collaborate with other teams, since everybody is crystal clear about what’s needed.
twined provides a toolkit to help create and validate “twines” - descriptions of a digital twin, what data it requires, what it does and how it works.
- The goals of this twined library are as follows:
Provide a clear framework for what a twine can and/or must contain
Provide functions to validate incoming data against a known twine
Provide functions to check that a twine itself is valid
Provide (or direct you to) tools to create twines describing what you require
In Anatomy Of The Twine File, we describe the different parts of a twine (examining how digital twins connect and interact… building them together in hierarchies and networks). But you may prefer to dive straight in with the Quick Start guide.
The scope of twined is not large. Many other libraries will deal with hosting and deploying digital twins, still more will deal with the actual analyses done within them. twined purely deals with parsing and checking the information exchanged.
Octue believes that a lynchpin of solving climate change is the ability for all engineering, manufacturing, supply chain and infrastructure plant to be connected together, enabling strong optimisation and efficient use of these systems.
To enable engineers and scientists to build, connect and run digital twins in large networks (or even in small teams!) it is necessary for everyone to be on the same page - the Gemini Principles are a great way to start with that, which is why we’ve released this part of our technology stack as open source, to support those principles and help develop a wider ecosystem.
The main goal is to help engineers and scientists focus on doing engineering and science - instead of apis, data cleaning/management, and all this cloud-pipeline-devops-test-ci-ml BS that takes up 90% of a scientist’s time, when they should be spending their valuable time researching migratory patterns of birds, or cell structures, or wind turbine performance, or whatever excites them.
At Octue, twined is used as a core part of our application creation process:
As a format to communicate requirements to our partners in research projects
As a tool to validate incoming data to digital twins
As a framework to help establish schema when designing digital twins
As a source of information on digital twins in our network, to help map and connect twins together
We’d like to hear about your use case. Please get in touch!
We use the GitHub Issue Tracker to manage bug reports and feature requests. Please note, this is not a “general help” forum; we recommend Stack Overflow for such questions. For really gnarly issues or for help designing digital twin schema, Octue is able to provide application support services for those building digital twins using twined.
