Hey Steven, good to hear from you! This is a good point from the EDTF, the section under your quote says:

1. Organisations label data with keywords and the authoritative source of their definition e.g. Term [Glossary Reference]

This is exactly what our Glossary is…

I totally agree that a dynamic online approach is right!

From discussions with DT Hub members, we’ve also seen lots of interest in geospatial data (and related terminology and approaches to facilitate greater interoperability with other data sets). In addition, organisations coming in…

@holgerkessler – this is a great question! We will use the meta data of the shared satus of a term to learn the connectivity to existing standards. 

Hi @holgerkessler and @Neil

A further thought is that this is a benefit of making this Glossary online/dynamic – it is eas…

Hey @Miranda, good question! Yes, if we look at things like Github and Stackoverflow in the software world we can see how effective it is to connect technical people in this way. interestingly it creates a vital learning environment!

We’re also seeing demand for this kind of…

Thanks @Simon for this excellent overview of digital twins. I particularly liked the context – how this builds on other 4th industrial revolution tech “waves” including IoT and AI.  A lot of the people I’ve talked to who have been interested in digital twins over the last few years have seen this as building on things that they are al…

Many thanks to Tanguy and everybody on this chat for all of your comments and questions.

 We are now coming to the end of our live discussion but we will keep this space open and available until the end of the day in case you have further thoughts or questions. We will continue to monitor the discussion during that time, but on a less…

Another question – for @Tanguy and all.

What are the most valuable/attractive use cases for digital twins in cities? 

(Maybe some of these might add more examples to help with the right time vs real time debate too)

Many thanks,

Nick

Hi Tanguy, 
Thank you for the video, very interesting.  You mentioned the need to manage the latency between the changes to the physical asset and its representation digitally.  What I wanted to ask if there are two distinct latencies:

1. The time from an intervention to when it is re…

Hi Michael,

Thank you for your insights!

As I mention in the video, we try to keep up-to-date with current international efforts on smart cities, so we would be very interested to engage in conversation on the topics you mention.

If there are any references to texts…

To get the ball rolling…a first question from me please to @Tanguy

In your view, what is an Urban Digital Twin?

Thanks, Nick

 

 

Welcome to the start of today’s Digital Twin Talk on Urban Digital Twins and a big thank you to @Tanguy from imec for joining us. We’re looking forward to your thoughts and questions related to Tanguy’s video – and maybe posing one or two of our own.

Please do start adding your thoughts by replying to the conversation thread.

HI Andrew,

This is a question we constantly ask ourselves – we provide computing for research of all sorts and its always a balance.  But we feel that there is continuing value of a specialist common hub with dedicated skills and resources for that community which can be shared.   We can us…

@Brian thank-you for your presentation and the interesting discussion. You mentioned DAFNI as a ‘cornerstone’ of achieving the National Digital Twin vision. I would be really interested in your perspective on what you feel some of the other cornerstones may be.

Hi @Brian and @Marion

It would great to hear what DAFNI is doing at a city level please and what data you have that might address city challenges. This is one of the areas where there is a lot of interest (and need) to combine data sets and models.

Many thanks

Hi Steven,

We will allow public/open data sets to be available through DAFNI – but we are also very aware of the licencing conditions and sensitivities of data.  So we would respect the data owners and allow them to release data as they want.  We would want to promote the FAIR p…

HI Simon,

An interesting question.   These would be like predictive twins – but the feedback into the physical system is less direct.  Certainly you nwould want to run twin models over historic data for learning and assurance – and also to validate your mo…

Please let us know what you think are the most valuable use cases for digital twins, either by replying to this post or by “Starting a new topic” in the Pathway to value forum.

 

We ran a webinar on third theme for the DT Hub, “Pathway to value” on 30th April 2020. During the session, we discussed where and how digital twins can deliver economic, social and environmental benefits, as well as considering some of the blockers to overcome. We also began to look at proposed activities for the theme and related priorities for…

Hi @olivierthereaux

Another question that I think people might be interested in.

You make a really interesting comparison with the world wide web. What can we learn from the work being done by the World Wide Web Consortium on the Web of Things related to data and interoperability for IoT please?

Agree with this also. One of the things we’ve been doing within BIM4Water is using Uniclass as a common classification for data items at an equipment level (pump, valve) – but one of our groups run by a colleague David Bell, has started to look at how we can apply this common classification at…

Hi @olivierthereaux

What is the relationship between a network of twins and a National Digital Twin for the built environment please?

3 minutes ago, Chris Jones (NWG) said:

Agree.

I noted the emphasis on ‘purpose’ in the GE definition – we also explored this with partners at Innovate East. It is clear that the need for common understanding (if not actually a standard) starts with defining the purpose and value.

Thanks Chris and Andrew. I think…

The first theme that we are addressing in the Hub is “Testing digital twin concepts”. This was identified as a key foundational element by the DT Hub members – to help increase understanding and inform the development of strategies and projects.

It will build on the Gemini Principles and generate recommendations to feed into the Natio…
