Better describe the partial inheretence of "realization" #277

Per https://docs.ogc.org/per/22-040.html#_realization_and_inheritance we should consider the definition of hydrologic realization.

https://docs.ogc.org/is/14-111r6/14-111r6.html#_hydrologic_realization

Currently:

A hydrologic feature type that reflects a distinct hydrology-specific perspective of the catchment or hydro nexus feature types. Shares identity and catchment-nexus relationships with the catchment or nexus it realizes but has hydrologically determined topological properties that express unique ways of perceiving catchments and hydrologic nexuses. Distinct from representation in that it is a refinement of the holistic catchment, allowing for multiple geometric representations of each hydrologic realization.

We may consider adding a clause that describes how the realization relationship is a partial inheritance relationship. "Shares identity and catchment-nexus relationships" is basically already saying it, but it should be more explicit.


Discussion of "realization" in 6.1 should be tightened up to better convey that a feature that is a "realization" is a partial representation of a holistic feature and that the "realization" association implies partial conceptual inheritance. The text currently blurs the line between a feature being a realization and there being a realization association between two features. There are feature types with realization in their name - so it's no surprise that the text blurs this point, but we need to do a better job of describing this dichotomy.


A table could be added describing the partial inheritance of each catchment realization in: https://docs.ogc.org/is/14-111r6/14-111r6.html#_catchment_realization

Similarly, a summary of what hydrolocation inherits from hydronexus could be added to: https://docs.ogc.org/is/14-111r6/14-111r6.html#_hydro_location
