ACTION-18 Review requirements for use case 34 (hierarchical regions)

Hi all


I had an action to check the requirements table (https://docs.google.com/spreadsheets/d/1PSnpJYQDgsdgZgPJEfUU0EhVfgFFYGc1WL4xUX9Dunk/edit?usp=sharing) for the use case that I suggested 


(https://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Select_hierarchical_geographical_regions_for_use_in_data_analysis_or_visualisation_.28Best_practices.2C_Time.2C_Coverage.29
)

In summary: yes relevant high level requirements have been captured and associated with this use case.


https://www.w3.org/2015/spatial/wiki/BP_Requirements#Relationships_between_locations_can_be_hierarchic



This obviously needs some detail (as do all of the requirements) - I'll add comments to the wiki.


I agree with the Barcelona workshop's removal of this use case from the 'Coverage' category.


My intention in attaching the 'Time' tag to it, was to note that hierarchical relationships between regions (for example administrative regions) frequently change over time.  This is something we can add to the detailed requirements about representing hierarchies.  It may well be covered by the 'Versioning' column of the Time worksheet.


Best regards


Bill
