Hullo!
Sorry for very slow response to your comment 
We are pretty excited by Wikidata (if it is embraced) as a collaboratively maintained dataset, it might remove the need for everyone to be separately updating their datasets (so less work), and it overcomes the issues of licensing which is an issue with the scrapers.
The data could be maintained via prompts and there are increasingly advanced tools to spot changes/ vandalism on Wikidata (Wikipedia is a great example of how the community manages vandalism and keeping data up to date). The main issue is the high entry barrier to use and extract data from Wikidata, we are working to create tools /platforms to make this easier.
Our current thinking is to try out developing a structure in the UK working with multiple organisations, friends and the Wikidata community to see if we can make it work.
