Hoi James,
The biggest bottleneck to innovation is our own community process. It is also an impossibility to get Wikimedia to consider how it performs for specific groups of students. Never mind.
When you want to increase the value of "Our World in Data", it helps when their identifiers are linked to Wikidata identifiers. The OWID identifiers are welcome on Wikidata when need be. The value is that as a consequence labels in all our supported languages become available. When information is to be shown in another language, only the missing labels are needed for best results.
When Wikimedia Foundation is interested in improving its functionality, I am quite happy to point to the lowest hanging fruits for the biggest number of people we could provide a service for.
Thanks,
GerardM
