1. Feature
ISO TC211 definition: abstraction of real world phenomena.
ISO 19101 and OGC OpenGIS® Abstract Specification Topic 5:
Abstraction of a real world phenomenon. 

The main difference is that ISOTC211 has plural 'phenomena' and ISO19101 only one phenomenon. As we can define one phenomenon as the occurrence of multiple phenomena, there is not really a problem. I propose using the ISO 19101/OGC Abstract Spec definition with examples, as conceptually the simplest, and people wanting to abstract complex phenomena are free to do so.



"Feature: Abstraction of a real world phenomenon. 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]]"
