Hi @Steven. (I remember meeting you at an ODI workshop some time ago, in the days when people gathered together in the same room!)
To take your questions one by one:
1. There are many different data models implemented by the different asset owners, and very little common ground between them. The challenge has been to map these many heterogeneous representations into the MUDDI conceptual model, and the future challenge is how to scale that. During the pilots we have worked intensively with individual asset owners to understand these mappings, and we have also tried to take a “step up” and identify common ground across different organisations in the same sector. As we move forward we’ll be looking to consolidate that common ground within sectors to come up with a standard set of mappings that we will have to make minor adjustments to as new asset owners come on board.
2. For the pilot, the data model has been implemented as a relational database, but early sandbox work did include some work with graph databases.
3. The NUAR data is at this stage is generally deemed to be at the “Group-based Access” point on the ODI data spectrum, i.e. accessible to authorised users only, with some locations and assets deemed to by highly sensitive and subject to greater access control.
