Hi Ian,
There is certainly a lot to think about here. Thanks for sharing your ontology, it’s great to see how much thought you’ve put into it.
At Northumbrian Water we’re not quite as advanced in our thinking in this area. We’ve focused on ensuring that we have clear mastering of key data items in our corporate systems and have clear classification and relationships within and betweeen these systems (typically oracle relational databases). For semi-structured data we’ve typically used XML or JSON filed in our Data Lake which have a pretty simple ontology and a limited number of links with our more structured databases.
Tools such as the examples above may well have assisted me in my role as Data & Information Architect, but I doubt many of our end users or other IT teams would be as interested (they just want it to work).
I’d be keen to know who you would expect to use an ontology system, and how you’d be able to keep it in sync with any changes to the data models/classifications of the corporate systems where the data is mastered.
Thanks
Andrew
