Consolidating Concepts: Workshop Results
Firstly, thank you to everyone who joined the concepts and principles standards workshop on the 11th of February. With 70+ attendees and a wealth of engagement, I feel that we managed to make some real progress in establishing the DT Hub community’s views on the future BSI Flex standard. As mentioned during the workshop, the slide deck presented will be given to the technical author and advisory group for consideration, acting as a seed for further standardisation development. A copy of the slide deck used with the comments and changes incorporate is available here.
In this article, I wanted to highlight some of the key insights that came from the workshop as well as provide you with the ability to keep track of this work as it progresses.
Scope:
Generally, the community appeared to be content with the draft scope, which had used the scope of ISO/DIS 23247-1 (Digital Twins for Manufacturing) as its basis. The comments received focused on types of assets, systems and processes which should be highlighted. Of particular note was the desire to include information assets, natural assets, and safety and control systems which have all now been included. There was also a strong desire to highlight the relationship to information and information management. A comment has been included to ask that this is done within the introduction as opposed to the scope.
Concepts:
After I had introduced a series of different conceptual diagrams, I was surprised to see a preference for the figure within ISO/DIS 23247-1. However while this figure appeared to be preferred, several attendees pointed out the need to articulate the scalability of the built environment; with mention made of effective visuals previously used by @Mark Enzer to explain the relationship between components, systems, and systems of systems. In addition, previous comments around the need to highlight the natural environment as a distinct facet were echoed. This led to the introduction of another figure from Flourishing Systems which highlights the built environment as economic infrastructure, social infrastructure and the natural environment.
Principles:
Having discussed the overall concept, we moved to the principles that should govern digital twins for the built environment. Using the original Gemini Principles as a basis, the community did not challenge the existing principles but did suggest a potential 10th, Provenance. Distinct from Quality, provenance would focus on the origin of information to enable someone to assess its potential accuracy or trustworthiness.
Terminology:
After discussing observable elements and references we concluded with Terminology. Using the existing terms on the DTHub Glossary as a basis, the community suggested several additional terms such as: interoperability, asset, system, process, system of systems, semantics and syntax. In addition @Ramy, a Northumbrian University PhD student, shared a figure and thoughts around Digital Twin uses and a “DT uses taxonomy” which he has also published on the DT Hub, here.
It is this sort of engagement that makes the DT Hub a community, thank you. As I mentioned, the outcomes of this workshop will be fed into the development of BSI’s Flex standard around digital twins for the built environment.
And there we have it. Please feel free to keep the conversation going by commenting below or directly on the slide deck. Stay tuned on the DT Hub for more news, updates and ways to get involved in the development of BSI’s Flex standard.
