Hi Clemens,

Thanks. I looked at the OGC Abstract Spec - so looks like OGC Topic 5 is out of date or has a small typo. As they are all meant to be the same, and the ISO TC211 spreadsheet also has 'phenomena', I guess the plural wins out, unless further comments later. And we point to the later standard as 19101:2002 is withdrawn.

Proposed entry now:

"Feature: Abstraction of real world phenomena. A digital representation of a real world entity or an abstraction of the real world. Examples of features include almost anything that can be placed in time and space, including desks, buildings, cities, trees, forest stands, ecosystems, delivery vehicles, snow removal routes, oil wells,
oil pipelines, oil spill, and so on. The terms feature and object are often used synonymously. [[ISO 19101-1:2014]]"

Chris
