Frans, "data" would be ok for me, too. Regarding your second aspect, I would agree, if it is the real-world phenomenon itself, but the feature is an abstraction of it. In my view, features are information resources. I guess this is a discussion item for the best practice work, so another reason for using "data" instead of "feature" for now.

For instance, a city can be regarded as a feature while its name, start date or geometry are attributes, not features. So this change would mean a drastic change in the meaning of the requirement. > The definition of 'feature' in the glossary now is 'abstraction of real-world phenomena'. To me that sounds suspiciously like 'non-information resource', which means that one could understand this requirement to exclude information resources. > In this requirement, 'facts' should be read as a synonym of 'data'.
