DRAFT NDT Architecture Principles

[dr.matt...@gmail.com]

Dear Colleagues,

A key part of the Information Management Framework is the Integration Architecture. The basic requirements for this were set out in the Pathway document. The attached draft document is a next level down document looking at the architectural principles that need to be considered.

 

We would welcome your comments on this document and discussion of any issues in this forum, or privately if you prefer.

 

Regards

Matthew

Thanks for Sharing Matthew, a good read, I will discuss with the Water Data Taskforce at the next meet

 

With regards

 

Max

Dear Matthew – what is your deadline on consultation for this document? I will aim to give some feedback from other participants of the WDTF in the next week or so, in the meantime some comments from me

 

• Requirements overview: the use cases around resilience are plentiful in water and Ofwat would be interested to see how a system could be interrogated to provide feedback on asset performance and maintenance activities in near real time
• Use cases (Page 8): do you want some potential use cases which could applied in the real world (I.e operational context in the water sector) if the answer is yes then some of those could be sent over, particularly with reference to “provide information to customers” or “support legal and regulatory requirements”
• Service catalogue: how far are you with defining the catalogue?

 

Happy to discuss… you have support from water.

Dear Max,

With minor updates this document will be going out for publication in the next few days. However, the publication will be for consultation anyway. Making it available on the NDT-FDM list is a pre-publication review to improve quality and give those closest to us an early look at what we are doing.

We have not decided on the consultation period, but it will be at least a month after publication, so that would be the timescale to make comments within (unless you want to tell me that longer is needed).

The plan for next financial year is to develop one or more technology demonstrators to test out possible technologies to implement the architecture.

I hope that helps.

Regards

Matthew West

Sorry for the late response to this very interesting document. 

The technical content seems reasonable, and the recommended architectural concept seems reasonable as a target.

What I wonder is whether NDT would realise more benefit by a more iterative approach. A series of 10 tasks is identified but they are mostly to define details before anything actually runs. There is one early proof of concept (good) which comes before certain functional developments. Perhaps it is simply not the purpose of this document, but I would like to see more definition of the iterative path towards the target architecture, where perhaps some benefit could be realised through operational subsets of the architecture allowing some lesser version of NDT to operate. That would help manage the considerable risk associated with the full NDT vision.

Dear Ian,

Thanks for the feedback, see responses below.

[MW] Good. That is what it was trying to do.

There is one early proof of concept (good) which comes before certain functional developments. Perhaps it is simply not the purpose of this document,

[MW] This should be (have been) set out in the Pathway document. The extent to which it is can be seen on Page 50 under Task 5. I can already see that things have moved on, but no plan survives first contact with the enemy.

but I would like to see more definition of the iterative path towards the target architecture, where perhaps some benefit could be realised through operational subsets of the architecture allowing some lesser version of NDT to operate. That would help manage the considerable risk associated with the full NDT vision.

[MW] Task 9 says: “An early proof of concept to validate the Integration Architecture components and their interactions. This will provide the basis to start producing open-source components to fulfil the Integration Architecture functions.”

So our approach will be to try to identify in the first place what already exists to meet our architecture specification with demonstrators/prototypes to evaluate what is available and establish what gaps there are that we need to fill. Our aim is that there should be open source software that can be deployed to meet the architecture requirements, though we plan to specify the architecture as a series of standards that developers can aim to produce software against.

 

I hope that helps clarify what we are proposing to do.

Regards
